This sliding arm trimaran is based on an earlier work, the CSA31.  It combines the best of Italian interior design with rigorous laminate design.  The sliding tube design draws from the earlier Trikala work.   The alloy tubes slide on teflon cleats to give an "in" beam of 12'-0" (3.66m), excellent for mooring in a marina.  This design has a very innovative interior arrangement with a private head space, and a very large galley.
