Hulls and tubes are done. They plan to build more from the molds. Price is still unclear.

Multihull Sailing Classes
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.

Track the Voyage of Lil Explorer
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.

Chris Anderson’s 20m Catamaran
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.
A little hull layup…
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.
