The L-7 is the brainchild of designer Mike Leneman. He wanted to design and build an 'entry level' trimaran. The top design priorities were: easy trailerability, solo rigging – launching – sailing, low cost, simplicity, and speed. Additionally, owners should be able to be store it in a slip, it should be suitable for minimal pocket cruising, and make a nice one-design racer.
The resulting folding trimaran is now available in kit form. The X-arms are pultruded, pre-fabricated fibreglass I-beams which slide in and out of the boat. The boat can be built in a relatively short period of time, as there are no cross arms to build, no fairing (the fibreglass/epoxy bottoms are provided in the kit), and the design is very simple. The boat sleep two inside and two in the cockpit.
This is a very fast boat; it has beaten 84 foot racing monohulls, as well as many Farrier-designed and other multihulls, in the open ocean in Southern California races.
