Description:

The L-7 is a trailerable, horizontally folding, 7 m (23 ft 5 in) trimaran that is available in plans, kit, or local custom-built from kit. The boat is very light and very fast (the prototype has beaten stock F-31s on a consistent basis). It is designed to be very simple, allows pocket cruising for 2 to 4, and is built from inexpensive materials.

One year after the first introduction, a number of kits had already been ordered.

The price to build, of under US$20000 [status Nov 2005] includes trailer and sails.
