From what I know this small tri sailed from Seattle to the San Juan Islands in 1971. It was built by glass over 2lb styrofoam foam. Apparently after a while the bottom glass was scraped by going over rocks etc and the inside foam became sodden. This may be exaplained as the boat carried no dingy and thus the trimaran itself was beached in order to access the shore. If to build again then hardchine plywood epoxy conscruction would be preferable.

What I like about this boat is that it is simple. It has optimised interior room over performance. No doubt the relatively beamy hull would not be fast. The hullshape would tend to over waves rahter than through them. Notice the fins on the amas, which free up the center hull from a centerboard case. It has a high cabin which increases windage, however it does allow for a much more comfortable interior.

As no heavy keel is required as in a mono and all the careful strengthening required to accept that large point load is not required, logic suggests that this would be an inexpensive boat to build for the size of cabin. It would be tempting to use a second hand Hobie 16 rig if one was available. In earlier times I had thoughts that the hulls of a Hobie 16 would be good as outriggers for such a boat. I now feel that this would be much more effort that it is worth and it would be best to build these out of plywood from the beginning.

I have not chosen to show some of the more yacht like multis out there. These tend to be more expensive, heavier and more work to build. No doubt they would be superior boats but logic suggests they would cost more money and time to make. Names that come to mind are Farrier F22, Scarab 22, L7 trimaran, Thomas Firth Jones, Kurt Hughes 23ft tri.
