18' Kayak Inspired Trimaran

This little Trimaran came about at the request of fellow watertriber Sundance. He liked the idea of a small Hobie Trimaran like the Adventure and Tandem Island but he didn't want to give up the comfort and security of his kayak cockpit with sprayskirt.

The resulting design uses 4mm stitch and glue construction and features an enclosed sea-kayak style cockpit and narrow 21" main hull which set her apart from her plastic competition. With 90 square feet of sail she will be equally as powerful as a Hobie Tandem Island but with a hull that is more easily driven.

In addition the design has folding crossbeams, a kick up rudder and centerboard as well as a skeg for extra trimming options and tracking in large downwind conditions.

Hull number one was cut out at B and B yacht Designs in Vandemere, NC in July of 2013 and is currently under construction in Florida. Sundance is also updating a blog with pictures of the construction. Look for her on the beach in 2014.

LWL: 18'-4"
Beam WL: 20"
Empty weight: 160lbs
Sail Area: 90 sqft

I noticed on the watertribe forum this boat is for sale. I couldn't help but check it out, and was pretty excited to see what you were doing for the mast step and furling.


I appreciate the details you posted.

What do you think about a system like that working on an Ulua?

I am taking my sweet time (moves, baby!, new job) finishing mine, but have rigged a couple attempts at a sail. I would love to have something that easily furled for paddling out. The Force 5 sail is a bit smaller than the 65sq ft called for in the design. But it should still be pretty fun. pics are at flsail.blogspot.com

Yeah I don't see why not. As some point the hobie bearing will reach max loading but probably ok for ulua with amas not too much larger than hobies. go for it.
