I just got permission to release this composite 12′ trimaran design to the public. It was designed to go into production in China. Plug on the project got pulled. It has an unstayed mast. Diameter in the model looks a bit large. It could also be roto-molded.
I had a visit today from the builder of the stretched 63 trimaran in Marysville. It will have two unstayed rotating carbon masts. He is a prodigious worker. This picture is from a couple of years ago. 63/65 trimaran. Note temporary placeholder beams.
