a nice short video of setting up the stations of the 37′ cat lines.

Got a bit of work done. New design book about there, needing only a couple of pictures that were still back at the office. I’m also kind of aiming the book at the future when its only available on Amazon, so putting in the hot links and so on.
But also created a new design being built soon up in Anacortes. A 37′ foam/glass cat with an aeroesque unstayed carbon mast. Builder is Jim Betts again.
I was looking for Kevin’s Face page to send some lines drawings to while travelling. I stumbled onto this picture of my 56 aero rig catamaran design Sarabi taken by a friend of Kevin’s, in Sidney, AU. Funny story. In this cat’s design phase, Philbrook was so impressed with Kevin’s hulls I designed, that he wanted some just like them but bigger. Good stuff.
Thomas Dalzell sent this link to me about vacuum sources.

Another page on Stuff Done Wrong. These Fassmer catamaran lifeboat/tenders are amazingly bad, in my firsthand opinion. They were clearly designed by someone who had no experience in catamarans. And the contract must have been huge as there are so many.
Notice in the picture that with only a few passengers, the bridgedeck is already underwater. It really is a catamaran. As a lifeboat,it would be OK. You are lucky to be alive. As a tender, I doubt if it could be worse for the job. A tender’s job is to ferry the elderly and infirm from the cruise ship to the shore. Half the passengers had difficulty walking on dry land anyway. The Fass has an ugly combination of pitch and heave inducing features. The bow overhang shortens the waterline, allowing more pitch. (It kind of looks like what a monohull designer thinks a catamaran should be looking like.) Aft, the draft is cut away for the prop, and that makes pitch worse. The low bridgedeck gets lifted by almost any wave, and the elderly really have to hang on. I was on one in only half meter waves and it was tilting up to 20 degrees, provoking moans from the passengers.
It is only 36.5’ (11.15m) long but weighs 26,455 lbs (12,000 kg). 300 hp gives 10 knots if you are lucky. Even within the envelope requirements, a real catamaran designer could have done so much better.
