The customer decided on the solid wing version of the trimaran runabout. The solid wing version below.  Microstation stopped being able to do any trim cuts so I can’t put holes in the shell anywhere. I have to get back where I can complain to tech again to find out why the fail.

I went rogue on a 32′ power tri runabout design. hope customer likes it. communication difficult on the road here.  Foam/glass.  30 hp gives low 20 knots empty and 45 hp full load.

Tried to make a radical look functional.  Opening doors on each side of cockpit.  Steps are aft to motor.

I finally got a picture of Trilogy 4 from Maui. I think that was my 48′ that was built by Kevin Millett some 20 or more years ago.  Originally called Hula Girl.

I just finished modeling the new SD31 tri with composite beams for customer on east coast of US. Very simple cruising tri, all of CM ply/epoxy for rapid build. Beams are plywood with some carbon.
It is demountable.

I first saw this trimaran design a couple of weeks ago and had to mull over what I was seeing. My first reaction was it needs a couple of feet of main hull added aft so it trims right in light air.

As I thought about it more, I realized that it was refreshing that he has broken out of the symmetric and “functional” thinking constraints.  It is visually appealing.  It makes me think maybe I can show some of the weird designs that I have been thinking of. 

Back when I went from architecture to naval architecture, the land one was stuck and formulaic.  The multihulls were where real innovation was going on, then.  Now, except for proas, it seems like multis have become formulaic. 

This unit will be heavy and expensive, but he broke out in a great way.  He loosened everything up.  I like that.  I do hope that it doesn’t mean that I have to put Hyundai ridges on everything now.  http://www.glyacht.com/

I found a whole lot of videos of my very early 26′ trimaran design, Caiman, from UK. That tri is significant in at least one way. It was back in the late 80s that someone named Kelsall visited its build site. I was practially unheard of as a designer then. While there, he decided to read my CM construction manual. I was later told that, where in the book I declared that I thought Nick Bailey was the best designer in the world, it enraged him. And didn’t KSS appear shortly after that? I had been doing CM since ’82.

Then later seadog Chris Anderson held ocean racing seminars on Caiman for its new owner.  I recall something about an upper coming loose…

These are not Muffalo quality, but interesting. 

And if I may, thats a pretty good looking boat for a nearly 30 year old design.   The design has been updated, but there wasn’t a lot to improve.  Guess I could slap it with a reverse bow stick, but that is more asthetic than anything.

I just got these pictures of Al’s new KHSD 20′ Spitfire trimaran launching on Vancouver Island. It looks great.  Am pretty sure those are beach cat amas, but except for the detailing, they could also be developed ply.  The work looks really clean.

One of my 37 trimarans out cruising.

Roger gave me this boat for an afternoon. I had a wonderful time. I wish I had one. My 12′ tri design with a lot of Roger’s updates in it.  It has speeds like on a bicycle.

I had forgotten that I got this nice pic of one of my 23′ trimarans sailing nicely in the antipodes.
