First, I’m still alive, though it was a close call. No, it wasn’t Covid-19, but something far worse, boredom.

I hate being bored and perversely, the less I do, the less I want to do. Thus, my creative energy that it takes to write these blogs or make YouTube videos seems to have gone into hibernation for the winter. Is it back now? Only time will tell, but since I’ve gotten a few emails asking if I was still alive, I thought I better get off my ass and write.

Second, also got an email complaining about the most recent appearance change on the blog I did a few months ago. They said it was harder to read because of the dark background. Honesty, I had noticed the same thing myself, but was hoping that I was the only one who noticed! See just lazy. Like hearing that strange noise in the middle of a passage and just hoping it goes away on its own (fat chance).

Tell me what you think of this new theme (background) and if anyone has any suggestions &/or improvements, I would be glad to hear them, though the easier they are for me to implement, the more likely it will happen.

Third, living on the Dauntless in the winter in Alaska is very different than crossing oceans or cruising to new and strange lands. More on this later, as it will be the topic in an upcoming blog.

Lastly, below is a blog I wrote mostly about the paravanes in 2016. I did write a summary of what I have done and the final paravane system setup. I will post that in the separate post.

While In Astoria, Oregon, last summer, I was finally able to get two new paravane birds.  Over 25,000 miles and 5 years, I had left the USA with 4 paravane birds, two 26″ and two slightly smaller at 24″ (as measured at the base of the triangle of the bird).  Going to 24″ was a mistake. I was so happy with the performance of the 26″ birds, I thought I would try the 24″ to see if they was as effective, but with reduced drag. Yes, just like a perpetual motion machine!

If I have learned anything over the last 6 years, it is that you can not escape the physical laws of the universe. Work (as in the physics definition of work as the product of Force and distance) perfectly explains the effectiveness of the paravane birds and the drag they produce.

Therefore, If I deploy just the windward bird (being the most effective), if it reduces the roll 80% of what both birds would do, then the drag will also be 80% of the total speed reduction had I deployed both birds. In the same way, the 24″ birds did not induce as much drag, but they also did not reduce the roll as much.

So, last summer, I decided to buy the 28″ birds, while in Astoria, at that glorious store, Englung Marine. With stores in the Pac NW, along the coast from Westport WA to Eureka, CA, it’s a must stop for any boater who wants the best bang for their buck.

I didn’t have a call to use them after the first day out of Astoria, but I did use them just the other day when we were returning to Wrangell from a a few days of cruising and fishing. The wind had picked up to mid to high teens from the south, producing a nasty very short period sea of 2 to 3 feet. With such a sea on the beam, this Kadey Krogen will get into quite a quick, deep roll of about 10 degrees to the lee and 5 or 6 to the windward.

Not terrible for what D and I have been through but a different story for the Vietnamese landlubbers. Also, the boat is set up for living aboard in port, not crossing the Atlantic, therefore, I deployed one bird immediately and was impressed how much the one 28″ bird suppressed the rolling.

Less is Not Always Safer, More is Not Always Better

2019: This was written in June 2016, but never published. The recent Trawler Forum post about paravanes made me look for what I had written already and discovered I had never published this. So , here it is.

June 11, 2016 – The Pacific Rim or Less is Not Always Safer

While the Pacific Rim is my destination, I am actually referring to the movie, Pacific Rim Movie. Not the best of movies, I still find it hard to get my mind around why a giant robot would be effective against a giant monster.  Let’s not even address the premise that this giant robot has to be controlled by two people.

Two people, they must not have done 3 legged races in camp as kids.

But I am sitting here in Largs, Scotland listening to the soundtrack, which is dramatic.

It’s good Dauntless music.

But besides the soundtrack, I do love Idris Elba.  And if you have not watched Luther, make sure you watch it from season 1, episode 1.

But then he really made his  name in The Wire as Stringer Bell. A depressing, but extremely insightful series.

 

I’m waiting for my next crewmates to arrive, Dan & Robin.

Brian left yesterday and of course he took the good weather with him.  From his second day, we had nothing but fair winds, sunny skies and beautiful cruising.

That also allowed us to get Dauntless more organized and in ship shape having sat in the wind and rain for 8 months.  There are still a few projects to complete.  My new goal for the Wallas DT40 heater is to have it completely installed before I reach Alaska.  Stay tuned. (Ha, still not installed, but I’m not in Alaska yet!)

I also had the opportunity to redo my geometry to determine the deepest I can run the paravanes birds without the possibility of hitting the prop or rudder.

Just to show that the laws of math and science have not changed all that much in the two years, the magic number is 17 feet, which is the same number I came up with two years ago.

Now, if you have been reading my blog for any length of time, you will know of my tendency to rant and rave about politicians who make decisions not based on any facts or science, but simply because it looks, sounds, tastes good.

Well, I am guilty of doing the exact same thing in this case.  Which further makes my case that the right number is the right number, more or less does not make it any better, just different.

So in my case, I came up with 17 feet.  This was also confirmed because my friend Larry on Hobo, another KK42, runs his at 18 feet because his poles are about 2 feet longer than mine.

So two years ago (2014), having the magic number of 17, I decide to make it 15 just to be on the “safe” side.  Sounds like a no-brainer right?  Then as I am actually rigging them, I decide to take another couple feet off, to make my no-brainer even better.

What could go wrong?  Am I not being 50% safer?  That’s what a politician would try to tell you.

No, I was being an idiot. Made even stupider because I of all people have taught wave mechanics and what happens to the actual water molecules in a wave.

In last fall’s crossing of the North Sea, it all became clear.   While crossing the North Sea from Norway to Scotland in September 2015, on the first day, (of the 4 day trip), the winds were from the NW at 20 knots, gusting to 37, producing seas 12 to 18 feet.

But the paravanes were not as effective as they should have been. I realized I was running the birds too shallow.  The paravane bird was getting caught in the rotor of the wave.

Waves are created by energy passing through water, causing it to move in a circular motion, producing a rotor. While the wave progresses, the particles of water in the wave itself, move up and down.  If you watch a leaf floating on the water, even though the waves move, absent current, the leaf stays in place.

Therefore, instead of pulling the boat down and thus reducing the rolling motion, all of a sudden the bird is actually being pushed up.  Sometimes this would cause the bird to fly out of the water.  Once I stopped and put another 5 feet on line on the bird, all was good and I got to Scotland.

So less is not always better.

And now, I will show you why more is not always better either.  Having Brian on our 2016 maiden voyage turned out to be, was a godsend.

I had a thinking partner who helped me articulate my thoughts and ideas.

The only moment where two people was a detriment and not a plus was in getting back to Dauntless on the dingy.  I got out, Brian got out, the dingy drifted away.

We started the engine, detached ourselves form the mooring and the dingy was reacquired 10 minutes later.

Had either of us been alone, we would have known the dingy was not secured.
