Grit. Voyaging under power on a beautiful day. Amazing finish inside and out.
link fixed now I think.
I recently had to review a chainplate on one of my COI cats and send a note to the USCG.
I see from the X-Ray report that the Aolani chainplates were not steel, but composite as I thought they were.
These composite plates are immune to corrosion, unlike metal ones.
I assume the builder used my layup schedule as I have sent earlier. I see no reason to doubt that.
They are easy for the builders to build in a huge safety factor.
Instead of being fastened onto a hull, these synergistically combine to both strengthen the hull and the chainplate.
Unlike the metal plates, these have some resiliency so make all the parts longer lived.
Any delta in the parts from the loads would show up immediately and early by cracks in the paint. Unlike metal plates which usually are not painted.
Attached find a picture of one of my other catamaran designs with composite chainplates. Note that he lifts his entire vessel with only the three chainplate locations.
The local Seattle formula 40 catamaran Dragonfly capsized during the Cow Bay Regatta. Not my design. It was originally from New Zealand and was originally named Simply the Best. It’s owner Pat is one of the best sailors I know. I hope to find out more soon, but I was told that it rolled over on a reach after stuffing into a kelp bed. It was a heavy air day. If it could happen to Pat, it could happen to anyone. I see the boat is on the hard in Everett, sans mast. Pic is on happier days.
Is it possible that Kamanu is 30 now? I did the working drawings in ’84 I remember. Am pretty sure it was launched by Schooner Creek Boatworks in ’85. http://kamanu.com
Cylinder molded developed plywood/epoxy. My first USCG certified passenger cat. Am sure Derek will froth if he hears about a 30 year old CM cat still going out every day.
As we know multis sail a bit differently from singles.
I got to come up through the Tim Ryan/Dave Linger/Larry Christensen school of trimaran sailing.
Not everybody can do that. So, a 2 day cruising catamaran class, in socal.

Here is a non Facebook link to be able to track the voyage of the KHSD 50 something cruising cat. Follow the Sailboat by satellite. When the map appears, if you click on the boat and each dot behind them you can get the location, direction, and speed.
