IBEX is next week in Louisville, KY.
I guess I will be skipping IBEX this year. It was great last year, but half the draw was being in Florida. Besides too much work here to take a week off. See
I knew that the PVC and SEN foam cores we use to build boats had some thermal insulation value but I didn’t think it was as good as house construction insulation foam. At the Fiberlay design conference I learned that it is almost as good as the insulation foams. For example 90 kg Airex is 0.24 BTU.in/sqft.hr.F which comes to R 4.2 per inch. Craig Riley tells me that the PET foam gets wildly even better results when in a vacuum.
Sarabi, Barry and Karen’s custom 56′ KHSD catamaran is back in the Northwest after a lap around the Pacific. This very gorgeous boat has an Aerorig. Rumor is she might be for sale. Contact me for now.
sarabi at rest
Reminder that tomorrow Friday the 10th is the Fiberlay Expo and Technical Training event.

Professional Boatbuilder selected the KHSD 24 trimaran for the picture of Design Contest 3. See
and I’m sure everybody has seen Romano’s video at
khsd 24 trimaran
I began building my first trimaran, Smoholla the Shaman the year that I began architecture school. That was 1977. I first sailed her the summer that I graduated. It was my home for a couple of years and at the same time, the fastest sailboat in Puget Sound, until Chaak came along. She was my CM construction method prototype.
She lives in the Chesapeake now, looking different but still sailing. How nice.
back when I had her
one of the Fury 65 catamarans
I found these videos on YouTube of the kHSD 65 catamarans Fury. They are all aluminum and certified for over 100 passengers.
http://www.youtube.com/watch?v=aJIhCwgEZTI&NR=1There are are least three and maybe four of the Fury catamarans in Cozumel and Key West. They must have been synergistic. The original owner managed to get three or four boats out of the same set of plans.
YouTube has a whole raft of Fury videos.
Check out this video from the KHSD 55 charter catamaran Palmetto Breeze. She sails out of Charleston, SC.
Historic Charleston. athletic women in bikinis; whats not to like?

KHSD welcomes Aquarius Fiberglass of Goa, India.
http://www.aquariusgoa.com/They are building another of the 65′ catamaran ferries. Construction is foam/glass with ply/epoxy internals. Welcome.
I found this very cool animation of assembling the KHSD developed plywood passenger ferry for Lake Victoria.
It has bigger cabins than I designed and will be wildly heavier. I tried. See http://ewventures.wordpress.com/2010/07/23/new-ferry-animation/
I got a picture of this plywood 37′ trimaran the other day. Database told me the plans went out in 1990 to Bora Bora.
It looks great. 37 trimaran
If you could answer these questions and forward the answers to me to help start the design process.
How long should be between charging batteries, once a day, twice a day, two days?
Shorttacking is fun
The sole should be flat
In light weather the boat should power if speed falls below 5 knots?
Dining seats must be face to face?
Galley should be out of traffic?
Head area should be separate?
All winches should be hand powered?
Boat should be able to be beached?

Most work will be upwind or downwind
Rotating mast or not
Fractional rig or not
Fuel choice, why?
Engine choice, why?
