Abstract
In a sailing catamaran provided with a forwardly directed pivoted arm carrying at the free end a third pontoon into alignment in front of either of the catamaran hulls a triangular truss assembly is provided bridging across the hulls. The apex of the truss assembly is then engaged to a point along the length of a mast which has its foot or base resting on the arm. A forestay stretched between the mast and the end of the arm supports a headsail while a mainsail is mounted on the mast.

In a sailing catamaran characterized by a starboard and port hull fixed in a generally parallel alignment relative each other by a bridging piece spanning therebetween including an arm pivotally connected to said bridging piece to extend forwardly therefrom and having the free end thereof engaged to a third pontoon for pivotal translation thereof ahead of a selected one of said starboard or port hulls, the improvement comprising:
- a triangulated truss assembly connected across said starboard and port hulls in alignment over said bridging piece including a mount at the apex thereof;
- a mast defined by an upper end and a lower end slidably engaged along the length thereof to said mount and having the lower end thereof engaged to said arm distal of the free end thereof;
- a forestay connected between said mast, at a point above said mount, and the free end of said arm;
- a mainsail mounted on said mast;
- and
- a headsail mounted on said forestay.
