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.
We finally get to see some pictures of Chris Anderson’s cat that he designed and is building. This is going on in New Zealand. North Island I think. This is a CM (cylinder molded) developed plywood vessel. Chris goes away back on the process. In fact he is in the original CM video.
If I may throw in a bit of bio: Chris led the team that designed the fly-by-wire controls for the Boeing 777. I’m surprised he has not also been interviewed by Wolf Blitzer this week.
Being from the antipodes, Chris did not know about Autocad, so he designed and used his own 3D modeling CADD software.
This unit will have 6 unstayed masts. I recall seeing the rig arrangement fastened to the top of his car; he was conducting tests.
Good stuff and great to see it move along.
Upgraded the video on this a bit: The layup on a 68′ cylinder molded hull currently under construction in Roatan: it’s speeded up quite a bit, this is about 25 minutes of real time. the half hull panels are approximately 11′ x 71′ – 4 layers of 3mm plywood and 33 gallons of epoxy.
