I’ve been ready to leave Vallejo for a couple of weeks. But the winds off the northern California coast are proving to be more persistent than the northerly winds off the Mexican coast last year. There is a blocking high pressure area in the eastern Pacific that just won’t leave. It’s certainly been there almost all spring. Doesn’t it realize summer is almost here?
One of the other manifestations of this weather pattern is the north east has been cooler than normal. Let New York have the brutal hot and humid conditions they are used to and let me have gentle breezes.
This is all stainless except for that compartment of brass screws on the right. I’m holding a 1 Kroner Norwegian coin. It has a hole in it and is not magnetic, so it goes with the washers.
So, in the meantime, I am organizing.
I had wanted to put off this tool and parts re-organization until this summer when Ti and Thien are with me. I had thought that it would be a good way for them to understand what things are, where they go and how we use them.
Oh well, the best laid plans of mice and men, sometimes go astray.
During the last two months as I have worked on various projects on Dauntless, countless jobs have taken longer than they should because I can’t find the right tool or part. Admittedly, it doesn’t help that I have spent 20 minutes looking for a flashlight that I could not find because it was ON and my brain was not looking for something that was lite, no matter how obvious.
I have also spent 15 minutes looking all over the boat, for a part I had just found only to have placed it someplace. 15 minutes! I knew I had put it someplace I wouldn’t lose it. Where was it? In my left hand!!
Talk about the right hand not knowing what the left hand is doing!
Crescent wrenches and sockets
So, a re-organization is necessary. I mentioned before that I had mixed stainless-steel bolts and screws with non-stainless. But I discovered I did not just have one tray organizer like that, but three or four. I also found fasteners that I thought I had but couldn’t find.
Now, everything is in its right place.
I also had the problem of finding four 13 mm wrenches, but not the one 14 mm I was looking for. Now, I have a full set hanging in the engine room (before I just had the 13, 14, 19, and large adjustable that I needed for the fuel filters).
Tomorrow, I’ll tackle my electric parts. I know I have a lot, 220 v, 110 v, 12 v, but the 5 or 6 containers I thought I had has grown to more than a dozen.
I had hoped to leave Vallejo for my trip north as early as a week ago. It wasn’t to be and with the eastern Pacific high showing signs that it doesn’t know that summer is here, I doubt I will leave before mid-month!
Dauntless’ Fly Bridge
Talking with a boating friend Friday who is very attuned to the weather in Northern California, he told me that normally, this eastern Pacific high is strongest in April, when it produces the strongest Northerly winds. But it’s now June and the April high is still here.
As a weather forecaster, the shoulder of the seasons, spring becoming summer, etc. is the hardest thing to predict. Each season has its own peculiarities, as well as the type and strength of the weather produced.
One crosses the North Atlantic in July because that’s definitely summer. Low pressure areas in the North Atlantic in July are the fewest and weakest of the year. Winds are almost never above 50 knots. When I was planning my first Atlantic Crossing, that’s why our planned departure was in July. June and August are the shoulder months, August weather can quickly transition to fall. Two sailboats were abandoned off the coast of France in a May storm, a few years ago. That I found myself in the North Atlantic in late August is a story I have related a number of times. Needless to say, the weather was worse than the month before and the successive three lows that rolled over me during my last 72 hours were definitely a sign of fall type weather; summer was over.
Dauntless’ Fly Bridge
Now, I’m waiting for spring to end. In the meantime, having gotten almost all my projects done, I am now cleaning up the small things.
My fly bridge has never looked so good. All my mild steel items, cotter pins, bolts, nuts, have been replaced with stainless steel. In the past, I used what was handy. During the last couple of months, I have spent days removing rusted fasteners or clevis pins that are ruined because they have a rusted cotter pin inside.
Lesson Learned.
I also added a line of lights for the galley and added a lighted led switch that purposely stays on all the time. I figured people new to the boat, Ti and Thien in particular, would appreciate some help in finding lights and things.
Blue Led switch is middle right just below the cabinetsDauntless’ solar panels
Over the next days, I am reorganizing my tools once again, as well as much used electrical parts.
Here is the latest snapshot of the weather patterns and winds over the North Pacific. First picture is today, the second picture is June 11th. No point in looking at anything else.
In the meantime, here is an interesting link to the video Ti made, Ti Cooks Pig Ears. with English subtitles. Yes, another Vietnamese delicacy. Who knew they did more than Bahn Mi sandwiches and Pho !!
North Pacific Weather Patterns Valid 02 JuneNorth Pacific Weather pattern valid 11 June
To refresh your memory, here is the screenshot I made on May 20th and posted in my Weather Planning post yesterday. It was pretty optimistic and in fact, if it would come to pass, it would be very good weather to get underway.
26th 0800 CM w narrow High
Here is the map for the same period, valid 0800 on 26 May, made today, the 23rd.
You can still see that little blue area of light winds, but now it’s over northern California about 50 miles inland.
Dauntless can’t go that I-5 route.
I want to point out that the other factor I take into consideration, in continuity. In weather forecasts, a critical component of any forecast, whether produced my machine (numerical forecast models) or a weather forecaster.
During my forecasting days, when I was actually getting paid to make weather forecasts of some type or another, there were times, I’d look at the current weather and forecasts that were put out by the person I relieved and not believe a word.
But the first thing a good forecaster takes to heart is continuity. My initial read may end up being correct, but it’s not helpful to the customer if the forecast changes significantly every shift change. This was particularly important during my days with the Alaska Fire Service. We were making 24 hour and 5 and 10-day forecasts.
They used the 10-day forecast to reposition aircraft and equipment and at a certain point in the summer, to send that equipment to the Lower 48 to support wildfire suppression in the west, once it looked like Alaska was done for the season.
The forecast for the 26th, from the 23 May forecast
It was critical that we (the two of us forecasters) stayed to the same tune and as forecasts changed, changed them in a gradual way to make sure the change was real and not an anomaly that existed in the numbers of the computer and nowhere else.
So, again, when I see a favorable pattern like I saw on the 20th for the 26th, I won’t spend much time on it, yet, because I want to see that it stays put over the next coming forecast runs. In this case you can see it pretty much disappears.
The last year of moving up the west coast of North America has been difficult enough. I’m not leaving Vallejo until I see that the big Pacific High moves off or a large low manages to displace it.
So, even though I will make a plan based on the forecast, to prepare myself and the boat to be ready to go, I’m actually not leaving until the winds actually change.
When I see the reality of the change, then I’ll look closely at the forecast to decide how long it will last. But until then, I’m just a bystander.
I don’t leave port based on a forecast. Or put another way, when I do leave port, I assume the conditions I have will be as good as it gets.
I thought this would be a good opportunity to explain my weather planning or better said, planning on the weather.
The fist picture on the left shows my main area of interest at the white dot, just south of Cape Mendocino. This is where the winds are the strongest. It’s a two day (46 hr) cruise to Crescent City, just north of that spot.
The sequnece from the 25th to the 28th seems to show improving condidions along the sure, with the strong Northerly winds moving off shore.
It could well happen. But what I focus on is the large overall pattern.
So while it is showing a small area of light winds along the coast, that if it came to pass as depicted, it would be ok, even good to leave San Francisco and head north, the problem is the area of favorable winds is very small.
I’ve always said that forecasts are more often correct, but id they are wrong, it’s usually an issue of location or time, but not the event. For example, a cold front with showers and thunderstorms is forecast to move thru your area in 12 houris time. In reality, it could be 10 hours, or 8 hours, even 6.but it’s happened.
Where it happened is another story, That’s what I mean my location. Forecasting snow anywhere along the east coast is always problematic. A lot of things ahve to fall in place for the forecast to be spot on at a given location or time. The snow-rain line could end up being 10 miles west of New York City. After the news media has panicked everyone for days, it looks\ like a big bust, but in reality, looking at the large scale picture, 90% of the areas that were forecast to get snow got it, same for rain, it was only that little band that was incorrect.
And that’s what I’m thinking of as I look at these three days of forecasts. The overall pattern really doesn’t change much. This little narrow area of light winds could easily end up being 20 miles to the east leaving me frighting winds and waves.
Most importantly, all the pictures I have posted here are the only things I have looked at to make this decision. This gives me an overview. Until the overview looks more than doable, there is not point in in spending time looking elsewhere, at other products or other models.
Om addition, if you find yourself trying to find the right model to five you the forecast you want, you are only cruising for a bruising.
Two days ago, here are the Windycom woeather maps I looked at to tmake my decision if 23 could leave on the 25th:
24th 1500 Overview25th 1300 OV25th Cape Mendocino26th 0800 CM w narrow High. It looks good, but it’s a sucker hole.26th 1300 overview27th 1400 OV27th 0800 CM28th 0900 Cape Mendocino28th 1200 OV29th 1200 OV
It’s 7 days to Washington’s Neah Bay. The first few are the most critical, since off the Oregon coast, the winds are more from the southwest in general. So, the California portion is the most difficult.
I’ll wait until the entire high pressure system moves east. I’d rather have 30 knots from the SW than 10 knots from the north.
Yesterday, I completed two things on the nice to do list: replacement of the Raritan water heater anode and replacement of a terminal block for my 120-volt neutral circuits in the engine room distribution panel.
The new anode is on the right
After two months, I’ve finally hit my stride and actually feel confident in what I am doing. That manifested itself in those two completions yesterday. Instead of taking a couple of days, they took a couple of hours and I didn’t have to redo anything.
This got me to thinking about a job interview I had just the other day. I found myself talking about the importance of not overwhelming students, especially students who may be far being in whatever work that needs to be done.
I mentioned in the interview that even when a student was far behind, let’s say they need to complete 20 projects or work assignments by years’ end. It’s already February and they have nothing done, with only a few months to go. It’s easy for a teacher to just be upfront about it, if you don’t get these done; you’ll fail.
I’ve seen teachers do that countless times. But it won’t accomplish the stated goal of getting that student to be successful, (though it does make the class smaller). If a student sees a mountain of work to do, they never get started, discouraged, not seeing how they can get it all done, they give up before they even start.
That’s me, now and then.
My driving lights are lighting up that sailboat
So, two months ago, when I made my list of the top half dozen things to get done before departure, I knew the last was far bigger, but I couldn’t overwhelm myself. I didn’t want to paralyze myself with indecision. Now, I know many of the readers here are successful boaters because they just see what needs to be done and get to doing it.
In the same way half of all students are impervious to the adults in their lives who get in their way, be it parents, teachers, or anyone else. They’re going to learn and be successful no matter what. It’s not by chance that the historic graduation rate in the last 50 years continues to be about 50 to 60%.
I’m not in the group. I needed a teacher to be able to at least steer me in the right direction or a teacher who could tell I was bored to death and challenge me in ways the curriculum didn’t. The same way a good teacher will give make-up work to a student in a piecemeal fashion. Do this for me tonight and I’ll give you something else tomorrow. At the same time scaffolding the rigor of the work. So, in a short time, they are whipping out stuff they never thought they could do just weeks ago.
Two months ago, starting with a list of 6 items, I knew I’d do more. I’ve done three times that amount so far. While moving the instruments on the mast, I knew to check the paravane fittings. The clevis pins needed to be checked and I wanted new cotter pins. I also noticed too much wear on the main fitting to the mast, so I needed to add some washers and new pins.
As I did more and more, sometimes taking a week to complete one checklist item, but I also did another half dozen items, that were not on the checklist. I became more confident.
Confidence is the other side of the equation. When I finally completed the LED project, which involved 4 wires, with four conductors each (a positive, and 3 separate grounds that control the three colors, blue, red and green), I was very pleased to see it all worked as anticipated. I had three switches to turn each respective set on or off, plus three additional switches to control the colors, since I figured I didn’t need any complicated controller.
That it all worked, gave me the confidence to tackle the 120v terminal bar, that seemed straight forward, but you never know. When that went well, without me having to redo stuff, I tackled the water heater anode and that went even quicker.
The order I tackled these projects mattered. I have read education studies that when formulating a test, the order of the questions can make a significant difference. The same questions in a different order can make a significant difference in student performance. Teachers have known this forever. If you put the hardest questions first, it discourages students. Why a teacher would do that is a story I will save for the book I’m thinking about writing. But it also goes to our overall 60% graduation rate.
When I took the test for my NMC Master’s license, the lights and signals test was the hardest for me. It was hard enough to remember red over green. Was that fishing or trawling or neither? But the day shapes were even harder for me, since I was not using them myself.
For a week I took practice tests. The passing requirement for that portion of the test was the highest at 93+%; meaning out of 33 questions, you could only get 2 wrong.
During my practice tests, I got anywhere from 65 to 80% correct. Well off the mark.
Test day came up and we took the other three portions of the test first that were easy for me. Then the dreaded lights and signals. The first 5 or 6 questions were “easy” in that I was sure of the answers. By the end of those 33 questions, I was positive that I missed only one!
Well, I missed two, but that was still enough to pass. I was elated, but I also recognized that the question order made a significant difference for me that day. Because I felt confident in those first half dozen questions, I didn’t stress and overthink the rest.
In the same vein, when I started working on the boat projects, I knew the order made a difference.
Since I whizzed through those two things yesterday, I decided today to tackle the Purisan project. Two months ago, I’d not even mentioned it because …
But now, it’s almost done, but that’s for tomorrow’s story.
I think it was time for anew anode for the Rartitan Water Heater
Slowly, but surely progress is being made.
I have completed the following:
Installation of outside LED rows and inside wiring, Amazon LED Link
The drving Lights on new brace with new brackets
Added another power line for the pilot house electrical panel and also added an additional ground,
Replaced the terminal block for the 120v system neutrals in the engine room distribution panel,
Replaced the anode for the Raritan water heater that I didn’t know existed until a few weeks ago,
Replaced the brackets for the three driving lights and replaced the two fog lights with stainless steel brackets I had made in Vietnam,
The fog lights are pointed down: to see the chain coming up and to make the boat more visible by lighting the hull, if I’m anchored in a busy area.
Tightened the thru bolts for the paravane pole brackets; replaced all the cotter and clevis pins with new stainless steel.
Closeup of the double row LEDs in the clear rubber jacket that makes them truly waterproof (we’ll see)
installed a set of fog lights to the spreaders,
Moved my Maretron weather instruments, GPS and my Groove WiFi extender to the spreaders on the mast,

The LED lights white. Can also be red, green or blue
Repaired (at the last minute before replacement) my 12v heating pad for my bed that is 5 years old and stopped working a month ago. Just before I went to buy anew one, I decided to have one more go at fixing it. I did.
My rewardThe aft deck lit by the LEDS
With the completion of Ti’s visa interview, a goal more than two years in the making, is done.
This High Pressure system will have to move on before Dauntless can get going north.
Waking up the next day, the feeling of thank god that’s done, cannot be ignored. Much like euphoria I felt waking up in Castletownbere, on the southeast coast of Ireland on the last days of August 2015, after completing my first Atlantic Passage.
Though as hard as it may be for some to understand, the Atlantic crossing was less stressful.
I understand the ocean, nature, weather and natural processes, formed by a fascination with physical science and systems engineering from as early as I can remember.
Bureaucracies on the other hand are a different matter. I’m smart, so I to think I understand them; but not smart enough. My life is full of the detritus of missed winks and nods. I’m more like the blind horse: What? You told me you (my boss, the bureaucracy) wanted an omelet. We did, but we didn’t tell you to break any eggs!
Thus, my well-found fear of bureaucracies. Now, that’s done. I can dream of the next steps.
I have a half a dozen things that must be done before Dauntless moves from her winter home in Vallejo. My goal will be to complete one a day, so that by next weekend, I’ll be ready to move my little Kadey Krogen from under the marina roof to an open slip, so that I can raise the mast and complete the rigging.
Seattle to Ketchikan
I am planning on being ready to leave Vallejo and start heading north the last week in May. Of course, the departure date will be set by the winds. I don’t mind bad weather per se, as along as the winds are from a favorable direction. That direction will be any winds with a southerly component. I’d rather have 30 knots from the south versus 10 knots from the north.
Getting or not getting “seasick” is a subject I have been meaning to write about for quite awhile now. I had partially addressed it in the excerpt below which I published two years ago. But I never made the follow-up post of my reflections on the subject and conclusions after the three month and 5,000-mile passage from North Africa to the Panama Canal. A video I made on our nice Christmas Day
Christmas Dinner with Micah on the Atlantic 2016
That’s 5,000 miles in strong, 18 to 36 knot winds produced by the northeasterly trade winds. While these winds are called the NE Trades, because that is their long-term direction, the actually winds on this passage were NE through SE, with three distinct swells from those directions with differing amplitudes and periods. This produced 8 to 16-foot seas with relatively short periods of 6 to 8 seconds from the NE thru the SE. Not the most pleasant conditions, even for a boat like Dauntless that loves following seas. In fact, this was the most difficult conditions with following seas we’ve ever encountered.
Some of the worst conditions possible if one is prone to seasickness, with the boat corkscrewing its way across the Atlantic at 7 knots. I expected that as I got my sea legs, sea sickness would be just a bad memory. But no, in fact, it was to the contrary. It got me to wondering what was really going on.
Stress builds and crossing an ocean is stressful in the best of conditions. For one, my insurance does not cover me past 200 miles off-shore. So, abandoning ship is not an option. For another, with a three-week passage, you are asking every component to work 24/7 for that time period and if something does go wrong, how to minimize the damage. Therefore, it’s a constant weighing of risks, rewards. E.g. Can I fix this problem with the engine running or do I increase the chances of something else going wrong by turning off the engine?
This is what I had written two years ago, just days after leaving Morocco for the Canaries at the very start of my second Atlantic Passage:
Morocco to the Canaries
Four days on the North Atlantic, 600 nm, four days, 1 hour, 35 minutes, what could go wrong?
For one, we found the weak link on this Krogen, it’s me.
In my first year of cruising, I would get sea sick maybe a quarter of the time. Now in my third year, it’s more like three-quarters of the time.
What’s changed? Who knows? I’m older, but usually one’s body becomes more adapted. No, I think the problem is in my brain.
When conditions are rough, I know to take a remedy or put on the Scopolamine transdermal patch. I’ve been using the patch for more than 3 years, now all of a sudden, the patch gives me a bad rash, but it’s also very effective as long as I put it on the night before departure.
With nice cruising conditions, or I should say, relatively nice, with winds and seas less than 15 knots and 3 feet (1m), respectively, I never had to worry, now, if the slightest unexpected event happens, I get seasick.
This last episode was one of the worst I’ve ever had. But I’m not 100% sure it’s “seasickness”. It’s more like my body gets a whole load of adrenaline and then when crisis is over, my body doesn’t know what to do.
…
We were heading 240 degrees, with Southeast winds 20 to 25 knots, producing seas from the south of 4 to 8 feet.
The paravanes work most effectively with seas on the beam, so our ride was actually not so bad with a gentle rolling of 8 degrees to the lee side and 4 degrees to the windward side.
On the 3rd day out of Morocco, I was in the galley filling my water bottle, when I felt the boat motion change. I looked out the salon window to see the windward paravane bird being dragged on top of the water, clearly broken.
I purposely take my time and want to remain calm. I finish filling my water bottle. I go to stop the boat, neutral, idle, then up to the fly bridge to retrieve the pole and the broken bird.
Dauntless is quite tame when not underway, in other words, she rolls much less. So, there was no big crisis.
The two spare birds are stored in the lazerette. The one that broke had been repaired in Ireland, as it had previously broken crossing the North Sea. So, I wasn’t too worried as to the cause. We had two spares in the lazzerette. The one on the starboard side was easier to reach, but as we tried to get it out, the fin of the bird became lodged under the generator exhaust hose. And the more stuck it became; the more stressed I became. I didn’t like the idea of leaving it as it, with its metal fin pressed against the exhaust hose and the wooden bird, so close to the hydraulic rudder piston. But after 10 minutes of trying dislodge it, I gave up, unloaded the port side of the lazzerette and got the other bird that was stored on the other side of the lazerette.
It took just another minute to replace the broken one and we were underway again, finally 20 minutes later, having spent most of that time, trying to get the one bird out.
Underway again, all was OK, but I was feeling very strange. Very strange.
I went to change my clothes, as I was very hot, sweaty and covered in anti-corrosion oil I had sprayed liberally in the lazzerette before leaving.
But after changing my clothes, I felt worse; like overheating badly, I figured a shower would help.
I shower, figuring that cooling off would make me feel better, but now, I can’t even dry myself off. It was a bizarre feeling. I wasn’t able to stand up or move. I dragged myself to bed and lay on top.
I figure I just need a little rest, but had wanted to walk around the boat, make sure all is OK before we get underway again. So, after a few minutes, getting more stressed because I knew Micah and Dauntless were waiting for me, as I go to put on my shirt, I became violently ill. First time that’s happened in years, even though, I get sea sick a lot and have that miserable nauseous feeling, I don’t throw up. This time I did.
I finally understood that I can do nothing but lay on top of my bed naked. I couldn’t even dry myself off. I use what little strength I have to tell Micah to make sure everything looks OK and to get underway.
I stayed on top of the bed and went to sleep.
Three hours later, I am up and OK. Like it never happened.
After I posted the above, my friend Dan added this comment:
“I have read of at least one person who has spent decades at sea who get sea sick every time they set to sea for three days or so. They, like so many, take a while to get their sea legs, and then they are just fine. What was interesting about this person is that they ONLY get sea sick when they are captain. If they are crewing on a boat, they don’t get sea sick at all. Their guess was that the stress of being captain was what caused the sea sickness.”

By the time we arrived in the Caribbean, I’d had two more stressful incidents and very similar physical reactions. Not only that, but suddenly, my skin was very allergic to the adhesive on this particular batch of Trans-dermal patches. So, I couldn’t wear it anymore and I’m left with these two quarter sized areas behind by ears of no pigmentation. No Michael Jackson jokes please.
I had also started to see a pattern. On Christmas Day, it was one of the calmest of the trip, with seas not more than 8 feet and winds in the mid to high teens. We saw whales that day and had a couple cruise with us for about 15 minutes. They were 30 to 40 feet in length and swam underwater next to the paravane bird.
Christmas being more important to my nephew Micah than myself, I wanted to make a special dinner, so I BBQed the last of four delicious Canary Island Tee Bone Steaks. The best ever.
As soon as I had served our dinner, I had that feeling of “seasickness” come over me. A bit of nausea and overall weakness.
Sitting in Martinique in the wonderful marina Le Marin, I had time to reflect on what was really going on. In all my cases of “seasickness”, the motion of the boat was actually less than it had been over any given period of time. Also, it was clear that I wasn’t sick before a crisis, I wasn’t sick during the crisis, but as soon as the crisis was over, I was sick.
Didn’t really sound like motion sickness to me, but more a reaction to stress.
I’s already stopped using the Transdermal patch and now I decided to not take any more seasickness medicine at all, when we left Martinique for the Panama Canal
I also decided to take a shower every morning before my watch and every night before bed. The shower in the morning seemed to calm me down. I had no idea why, but starting my day at a lower anxiety level seemed to make a significant difference.
From Martinique to San Francisco, a distance of 3,600 miles and 90+ days of cruising, in some of the worst seas I have ever encountered, I’ve taken an anti-nausea medicine only twice.
I now understand that that terrible “seasick” felling was my body adjusting to the lack of adrenaline that the stress had produced and my para-sympathetic system was now getting my body back to normal.
Clearly the shower in the morning or before my watch, makes a significant difference.
And then in the November 30, 2018 Wall Street Journal, they did a book review of the book, Never-Home-Alone
And the shower in the morning starts to make sense scientific sense.
Here is the article from the Journal (bolding and underline is mine):
BOOKSHELF
‘Never Home Alone’ Review: The Critters Chez Nous
In trying to rid our homes of insects, fungi and the like, we’re forcing the species around us to evolve ever faster—often at our own expense.
Lisa Margonelli reviews “Never Home Alone” by Rob Dunn.
When Rob Dunn was a young ecologist he rummaged through rainforests in search of biodiversity. More recently he discovered another type of wilderness: In a study of 1,000 houses in the U.S., Mr. Dunn’s team found 80,000 kinds of bacteria and archaea hidden inside—that’s at least 10 times the number of bird and mammal species observed in all of the Americas.
He soon also unearthed in our homes some 40,000 kinds of fungi and hundreds of insects, many yet to be named by entomologists.
“I was ecstatic,” Mr. Dunn writes. “Back in the jungle again, albeit the jungle of everyday life.”
In his fascinating new book, “Never Home Alone: From Microbes to Millipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live,” Mr. Dunn brings a scientist’s sensibility to our domestic jungle by exploring the paradox of the modern home: In trying to make it “clean,” we’re forcing the species around us to evolve ever faster—often at our own expense.
Mr. Dunn is a fine writer, wringing poetry out of the microbial explorations of Antonie van Leeuwenhoek, who spent half the 17th century documenting all the tiny living things around him—in his neighbor’s mouth, in the snow, in cheese rinds and in wasps. Leeuwenhoek “was to become an astronaut of the miniature,” Mr. Dunn tells us, “all alone exploring a realm that was more diverse and elaborate than anyone but him seemed to understand.”
Mr. Dunn also gracefully explains, without getting bogged down in details, the technology that has allowed scientists during the past decade or so to sequence the DNA of millions of previously unknown microbes, making his book an excellent layperson’s guide to cutting-edge research.
Mr. Dunn’s larger purpose is to explain how the ecology of the home has gone awry. Once upon a time, we lived in leaf huts, with interiors that looked a lot like our outdoor environment.
Soon we moved to round houses, then square houses and finally to air-tight apartments in cities.
Now we close our windows, use products that claim to kill 99% of germs and have unknowingly domesticated bedbugs—so they adjust their workdays around ours.
Our homes no longer resemble the garden outside but have a weird human-centered microbial signature that is also found on the International Space Station, and that’s not a good thing.
The problem, according to Mr. Dunn, “is not what is present but instead what is absent. The problem has to do with what happens when we create homes devoid of nearly all biodiversity except that which falls from us and then, for twenty-three hours of the day, we don’t go outside.”
To understand how mundane and occasionally deadly this evolutionary project of ours is, consider the shower head. In many American homes, water is treated with chlorine and chloramine, which kill pathogens but not mycobacteria, a genus that includes the cause of tuberculosis.
Meanwhile, in homes with water drawn from wells, nonharmful microbes flourish, including mycobacteria’s natural competitors.
By wiping out all the other bacteria in chlorinated water, we create environments where troublesome microbes thrive and even evolve.
This has led Mr. Dunn, together with his colleague Noah Fierer, to find that mycobacteria in shower heads can accurately predict instances of mycobacterial infections, as well as the regions where these outbreaks are likely to occur.
And yet mycobacteria are not entirely bad. One species has been found to enhance serotonin production, which can lead to greater happiness and lower stress. Mice exposed to a species of mycobacteria are more likely to remain calm when facing a bigger, more aggressive mouse.
Might this also explain how a morning shower helps us deal with a stressful commute and a bad day on the job?
These twin stories—of scientific discovery right under our noses and the perilous impact of our unwitting genetic engineering—thread through Mr. Dunn’s book.
Cockroaches were once easily lured with glucose baits but have now rapidly evolved to dislike sweet things. Good strategy for the cockroaches, more troubling for us.
“Just as military specialists study the battles of the past to prepare for the future,” Mr. Dunn suggests that “we might consider our battle with the German cockroach in contemplating our own evolutionary future.”
“Never Home Alone” is a prescription for more biodiversity in the home and, more specifically, a plea for more attention to ecology. The more we understand how different creatures interact and influence our immune systems, the healthier we may be. But in the service of getting more people into ecology, Mr. Dunn believes the field needs to deliver tangible products.
He wants to systematically explore the species in our homes to determine which ones could contain useful chemistry. The camel cricket, a previously unnoticed and rarely studied thumb-size little bugger that lives—possibly by the billions—in American basements, has gut bacteria that can break down black liquor, a highly alkaline toxic waste produced by the paper industry.
The thief ant traipsing across your kitchen counter also produces an antibiotic that may eventually be useful against hard-to-fight infections. Personally, what I want to see is a home “makeunder “show dedicated to “rewilding” homes—similar to what you’d see on the Learning Channel, only more anarchic.
A bunch of giggling scientists show up at the door, toss the hand sanitizer, the shower head, the Sheetrock and the fungus-laden air conditioner.
In their place, they hand the homeowner a bar of soap, throw open the windows, install a ball of spiders to fight flies in the basement and start a batch of sourdough—all in the service of re-creating the garden indoors.
No doubt there will be tension in the idea of a wild domicile. Even King Tut, Mr. Dunn notes, was buried with a fly swatter.

Since I’ve been back in HCMC, I don’t even do the little I have to do.
My Orange Juice and Yogurt today (cost $1.80)
What do I really have to do?
I’d like to get my electronic Dauntless logs up to date. I’ve been stalled in August 2017 for the longest time. I need to re-organize my hard drive on my laptop, so I only have one current directory that I keep backed up, with other files, music and pictures, stored on my external drives.
Not exactly the most onerous tasks. So, why aren’t they getting done?
Fundamentally, I think I’m simply too much of an extravert to sit home and be productive. I’m writhing this post now, while sitting in one of my two favorite cafes, in this case, Coffee Bui Van Ngo, about an 8-minute drive on the motorbike from my house.
Sometimes I get Cappuccino, as I find it as good as in Italy (undrinkable in USA)
I’m enjoying a yogurt with ice and orange juice. Usually I get it blended but decided to get wild today and try it this way. I’d already had my coffee at home. Vietnam is one of the few places where I find almost anyplace, I go the coffee is as good as I make at home.
In fact, New Yorkers would feel this is the one place they would feel at home in regard to coffee. The normal coffee is very strong, with milk and sugar; what New Yorker’s call “regular”.
I was 19 years old, driving across the country for the first time with my first car returning to the University of Washington for my second year.
When i want an Avocado Smoothie, I go to this cafe. (cost $0.90)
I stopped late in the evening in Montana, just south of Missoula, to get a cup of coffee since I was planning on driving thru the night, on my way to Kennewick, Washington. When I asked for a coffee to go, I was asked how I wanted it and I told her “regular”. She gave me a funny look, but minutes later my coffee in a container and bag arrived and I was on my way. Always pressed for time, I got underway before trying it down the road.
Black and bitter. Ugh.
That’s how I discovered that not everyone drank “regular” coffee.
That got added to the list of Things Aren’t Like This in NY. Already on the list was the shocking discovery that the buses stopped running in Seattle at 11:00 p.m. 10 years later, I discovered it was the same in London, as we found ourselves with scores of others trying to find a taxi.
How anyplace that calls itself a major city has a transportation system that goes to sleep makes one understand why people like cars so much.
But today, no tilting at windmills, the Vietnamese coffee is rich, strong and creamy. Perfect over ice, as most Vietnamese have it. The ice dilutes it to a perfect state, still very strong .
So, getting out of the house seems to give me purpose.
The owner and his girl at my smoothie place
Being around people is part of that process.
Though, on Dauntless, I do get restive, but there is always something physical for me to do, which I really enjoy. In a perfect world, Dauntless would be a not too far drive away. Much like when she was in providence , Rhode Island. Living in upper Manhattan, I could drive to Dauntless in about 4 hours. Stay a few days, get some work done and return home for the long weekend.
Even now, If I was anyplace in the States, I’d consider flying to her in Vallejo, staying 5 or 6 days, then home again. Round trip plane tickets can be had for around $300. I’d do that.
But a trans-Pacific flight is a horse of a different color. 15 hours from the west coast to Northeast Asia for a connecting flight of 4 to 6 hours to Saigon. Sometimes it ends up being two red-eyes. One is bad enough.
I’ll just have to be more disciplined and get out more.
During the last week on Dauntless, getting her ready for the winter without me, tears all around, I realized how sweet it was to work under a roof.

Looking aft with the mast down, under the roof of the Vallejo City Marina
I loved it so much, I changed my project priorities a bit. I figured it made the most sense to do those things that are difficult to do under normal circumstances. It is such a pleasure to sit on the fly bridge, out of the hot blazing sun or the cold wet rain. With the mast down, I didn’t have to wrap one arm around the mast and hold on for dear life. Under such ideal conditions, I realized I had to get all the things done I had been contemplating for years.
Four years ago, getting Dauntless ready for her first ocean crossing, I took what was given. Unlike the Lexan storm windows which were done in the last hours, the Maretron system and instruments on the mast were completed with days to spare.
One thing that has sunk into my dense brain is if I don’t have a clue as to what I am doing, then at least do the simple solutions instead of making complicated ones. To that end, I mounted the Maretron instruments on an existing antenna arch that extended forward and was above the radar.
It was the simplest solution and worked well enough for four years, but now, I wanted to make it better. I have felt that the weather instrument that measures all the normal weather parameters, including wind speed and direction, is not in a clear air stream with winds from the stern. As you know, this Kadey Krogen loves following winds and seas, therefore if the data is being affected under such conditions, it’s not ideal.
The other issue that is also related to stern winds is that every once in a while, lines related to the paravanes, get enough slack that over time, being blown forward, like 21 days in following winds and seas, that they were easily snagged on those weather instruments or the bracket itself. In the first years, more than once, after deploying the paravanes, I discovered that the weather instrument arch was carrying the weight of the paravanes. Not good. (Though it does confirm the forces on the paravane system are as expected).
Just too many times, that antenna arch has been seconds from disaster. Time to get rid of it. The Maretron cable that runs inside the mast must also be replaced. So, the Maretron WSO and GPS will be mounted on the spreaders. In addition, I will mount my Wi-Fi extender antenna and I hope to also move my current AIS antenna to the spreader. Currently it’s mounted on the cowling of the fly bridge near the helm. It’s too low. Many times, it will not see big ships until 5 or 6 miles away. At the Dauntless speed of 6 knots and big ships possible speed of 20 knots, that still gives me more than a 10-minute warning, but that antenna should be maximized just on principal.
Plan for the Mast Spreaders March 2019
I also need to remount the two Chinese LED spreader lights. The lights themselves, bought 5 years ago on Amazon for $20 each, have been great, but the mounting hardware is mild steel that rusts badly. I have a way to mount them directly to the spreaders, without the steel hardware. Since I am doing that, I will also change the electrics a bit and add an electrical circuit to power a LED stripe that I will also mount on the mast.
Now, your thinking, while I have eliminated one protuberance, I have made the spreaders much more complicated. That’s true. But I have a plan.
I will also add a 1/16th Amsteel line from the top of the mast to the end of each spreader, then forward to the front of the radar arch. Looking aft from the bow, this will look like a triangle. Looking from either side, this will look almost like an obtuse triangle.
Now, I have not added this yet. This will happen in March when I return to Dauntless, but in my mind’s eye, I see this little line as making it much more difficult for a loop of any line to become snagged around the spreaders, radar arch or the mast itself.
It’s 20:30 hours. I had a glorious day in all aspects. The weather could not have been better, 72°, light breeze. Dauntless is under the roof, no problems with sun or rain. Of the two projects I started out this morning to get done: one’s done and the other two are almost done.
this picture was taken just 5 hours before my departure. I was so enamored with the sunset that I really did not look at the situation. Notice the solar panel array on the port side stern of the sail boat in front of me.
But this evening, I felt a disquiet. My project list is not even a quarter done and I’m leaving for the winter in 5 days.
Then I realized it’s not about progress on the projects, days left, or anything else. It’s that I’m alone.
But even that is not so simple. In fact, my happy meter is well above my “normal”. Boat wise, relationship wise, career wise, pretty much everything, I’m quite happy about. So why the grumpy face and thoughts?
I’m not feeling lonely; but something is still missing.
Then it occurred to me. My entire life, from as early as I can remember, has been about teamwork. Working with others to a common purpose.
I can’t even begin to tell you the times I sacrificed personal accolades for the sake of the team.
All my successes in life can be attributed to building and nourishing successful teams.
Even when I started my teaching career, I did not become a successful classroom teacher until I realized that I needed to make the students in each class understand that they were a team and needed to help each other for their own learning, not for me.
As a high school principal, it was harder, because professionals in education have never been taught anything about teamwork, but the successes we had were all because the entire staff was working together for the good of our students. Sure, there were a few bad apples, but despite them, we got a lot of kids to college and success that would not have happened otherwise.
Then, I look at the other side. Even though I was quite successful selling cars, I hated it. The General Manager at a very successful dealership once made the comment to all in our sales meeting that, “Bost, probably tells everyone that he is a lawyer” I wondered how he knew, though I didn’t pick lawyer, I just never told anyone I sold cars.
While I was successful there, I was a duck out of the water.
With my project list for Dauntless, the list would feel less daunting if my teammate was here. Teammates don’t let you get overwhelmed with small stuff and they convince you the big stuff isn’t so big.
Even better, teammates give you that Cesar Milan nudge or click, that gets you off the obsession and back on track.
That’s what I miss. Otherwise it’s too easy to go around in circles or become obsessed about the unimportant.
In teaching, once I realized that I had to convince the students that they are a learning team. One time, I noticed one of my special colored pencils was missing from my grade book, that was open on the first row of desks. I used color codes for different types of work. I was irritated about it and started complaining to the class about my missing pencil.
In a New York minute, which in this case was probably 30 seconds, one of the students calls out, “OK, we get it Mr. Bost, now can we move on”
I snapped out of it. It was the nudge I needed.
(A couple of days later, in walking around a different class, I saw my pencil in front of one of my problematic students. Without a word and I just took it back. Months later I finally got that student to start working and she passed with a 72 out of 100 on the NY State Regents. She worked hard, finally. How we got there, is another story, I’ll save for the book).
And I wouldn’t have spent 3 hours on the Maretron power problem without checking the fuse from the very beginning.
Oh Richard, since you know the circuit had power until you shorted it, why don’t you check that fuse once again?
Oh yeah, that’s probably better than spending the next three hours on this connector!
For a little, non-electronic boat, I sure love my Maretron data. I have 9 modules:
two to communicate with everything else, (USB, IPG) and the N2K Viewer
two for the fresh water tanks, (TLM),
one solid state compass, (SSC),
one GPS, (GPS),
one depth sounder with paddle wheel and lastly, (DST),
the love of my life, my (WSO), the weather instrument.
The solid sate compass seems to work better with my ComNav autopilot. In addition, it gives me the roll and pitch data I often quote in my blog.
The weather instrument is also solid state with ultrasonic wind measurement. Considering I installed the system myself over 4 years and 20,000 miles ago, I’ve had few problems.
A glorious day in Vallejo, under a roof, with the mast down, facing aft
Coming west across the Atlantic, the constant winds behind us and to the side, from 15 to 35 knots for 528 hours or 22 days (No, I didn’t stop to change the oil) took a toll on my connections on the mast. Everything still worked, but occasionally, if a line got caught it would put enough strain to disrupt the connection until I freed it.
So, one of my projects now is to redo all the connections in the system. I also now slather everything in dielectric grease. So much so, that I almost put it on my pancakes the other morning.
One of the offending connectors
So, the day started out so very well. Sitting on deck, with the mast down, Dauntless under a roof, protecting us from the elements and sun, I thought about climbing up the mast in Cabo San Lucas, in hot, 95° sun, holding on the mast with one hand, while trying to tighten the 5 little wires inside the plug just under the WSO.
I was in hog heaven. I carefully tool the plug apart, unattached the 5 little wires, and recut them all and trimmed them. Now, I knew power was still on the system. Before I started any of this, I wanted to make sure that it was only the WSO that was incommunicado. So, just as I was thinking that I would have to be careful in cutting the positive power line, meaning not to cut it with the ground wire at the SAME time; I did exactly that. The little spark, showed me that I’d f..ed up.
Sure enough, when I go below to check, now the whole Maretron system has no data.
Had I shorted out something serious? Was there a fuse in the system? If so, where was it?? Who the hell installed this system?? Oh, it was me!
Let me check the computer cabinet. Open cabinet and what do I see, the fuse block that I put in 4 years ago and even nicely labeled at that.
It went downhill from there.
To check the fuses, I had to pull them, to do that I needed to power down the whole system. That done, I pulled each fuse and looked at it very carefully. Very carefully (for those of you who already know the answer, don’t spoil it for your dear ones who are also reading this).
They all looked good. I powered the system back up. That takes a few minutes because the modem and router have to be booted up before the computer otherwise everyone gets confused.
At this point, I noticed that the little light for the Maretron circuit was not lit on the router until I turned on the computer. I hadn’t noticed that before. (and in the future, I will explain that issue).
No change. I went back to the fly bridge. One of dozens of trips I would make over the next couple of hours. I figured I had screwed up the wiring of the plug. I took it all apart again. I convinced myself that possibly the ground shield covering was touching one of the data lines. I put it all back together again, rebooted the entire system and alas. No joy.
At this point, I’d spent an hour on this. I pulled the fuses again. They still looked good. I even held them up to the light. But finally, just to be sure, I changed the 5-amp fuse that powered the Maretron system. Surely now, it would work.
Still No Joy. Now, more than ever I was convinced it was the plug. The plug was the only thing I had worked on.
Back to the flybridge. Took plug apart again. Put it back together again. Rinse and repeat.
I got my electric meter out (finally you think), check the plug for the umpteenth time. No power.
I go online and check the Maretron site. It tells me I should see 60 and 120 ohms between certain lines. I see exactly that. But still no power. I must have shorted something else out. Where did I install the power tap?
Oh, I remembered where the power tap was because it’s in the port side pilot house wire race that is so full of wires I have trouble getting the teak panel back in place.
Other than no power, the continuity on the plug and lines tested correctly.
I’ve been working on this for three hours now. I return to the computer and fuse block.
I finally decide to test for power in the fuse block. Umm, the Maretron circuit has no power here.
I pull that fuse and check it. No circuit. I check the old fuse I had pulled out, no circuit.
I got fuse number three and checked it, a circuit.
I stick it in and low and behold, power.
Two hours earlier I had replaced a bad fuse with another bad fuse. Both fuses showed no sign that they were open. Both had very clear “Z” wire that wasn’t broken.
