Surtees Multihull Designs offer comprehensive building plans for the Multihull Owner Builder.  Designs range from Day Sailing, Coastal Cruising and World Cruising Catamarans and Trimarans.
These designs have the option for my proven “lateral resistance with inertia” for POSITIVE TACKING to windward in all sailing conditions.

Surtees Multihulls are currently developing a 7m and 9m folding racing catamarans. These cats are designed for short coastal racing and to take line honours. They definitely have the WOW factor, plans available 2012.
