Last week I got to visit the boatyard of Thain Boats, the builders of the Uganda ferry cats. They are finishing up a SIP panel houseboat with a variation on some hulls that I designed a while ago.  Albert, the lead, intends to stack them in the future and stick the internals in with Plexus on the site.  These are so much better than the alloy ones that the developer used to require.

Solid knitted glass laminate.  No core, hence all the frames.

Someone sent me this picture of a pair of my 75′ ferry cats that were bootlegged in Belize. Am in discussions wth the legger now.

This strip cedar 45′ has been built in Texas. I understand the hulls are for sale.  I imagine they could also be used in a COI cat.  Let me know if anyone is interested.

These are not all catamrans but are certainly retro futurist.  Spaceship looking watercraft. http://www.messynessychic.com/2016/04/20/river-rockets-of-the-soviet-space-age/?utm_source=sendicate&utm_medium=email&utm_campaign=2016-04-25+A+weekly+newsletter+from+Paris

I don’t know yet what design, but I have always said that a catamaran with keels is the worst possible craft to run aground in.

On a mono, the crew can kedge off of the top of the mast. I’ve been there. On a tri, the slackers can all be ordered onto the ama.

A cat with keels is a whole difference scenario, and better hope that you don’t get neaped.   A cat with boards can stop, determine the way back out, lift the boards, and flee back.  Keels don’t allow that.  Thats part of why I prefer boards, among all the other reasons from pointing better to being able to perform repairs while underway.

I see that my friends at CSR boatyard are again hosting the famous Fremont painted naked solstice cyclists, paint prep. The riders will do their body painting at CSR.  Maybe this year Scott can coach them that green goes on the right, red, well you know the rest.  http://www.solsticecyclist.org/

A soft mast hound. I like that. It should give rotations of over 90 degrees each way of centerline. I’m not sure if they are reliable enough for cruisers yet, and might be more costly than a classic metal one or a metal/composite one. Definitely something to think about.
Years ago a 3D modeled the ideal hound which was the three wires morphing into braids as they reach the mast, and spreading out onto the mast as epoxied laminate. It could not have worked, but was a wonderful conceptual take-off point.  This is a way to make it work.

“Rigging
Most of the hardware is on the boat and we are now working on rigging. Here is a picture of our new hounds fitting which is the terminus of the cap shrouds and forestay that hold up the mast. Two titanium thimbles have been threaded into the front of the mast. The lines go inside and are pinned with 5/8″ titanium rods. This is a lot cleaner (and lighter) than our old hounds fitting which was a huge aluminum welded thing with metal shackles. Luke Burritt from Yachtfitters is the mastermind behind this great solution to terminating synthetic rigging to the mast.”

These clear photovoltaics are wild.  Imagine your catamaran windows also being your electric source.  No idea when Lewmar will start making hatches from this glass.

I was looking for some other pictures when I stumbled onto Gustl Spreng’s construction pictures of his KHSD 63 cat from almost 20 years ago as I recall.
I knew it was a variation on CM construction but I had not had chance to study these pictures for some reason.
I looks like he made a series of female stations and then forced the plywood into that shape. It must have also been vacuumed.  The results looked excellent.  I recall that core was then bagged into the inside, along with triaxial on top?

I cannot find Gustl in the googles, so if anyone helped with this hull construction, you are welcome to fill in.
