ABSTRACT:
A triple-hulled sailing vessel has a mast on its center hull. The lower end of the mast is pivotally connected to the center hull and a rigid transverse brace is connected to the central hull so that it pivots as the mast pivots; the outer ends of the brace are pivoted to the respective flanking hulls. Links are pivoted to the flanking hulls; these links extend upwardly towards the mast and are pivoted to a connecting member which is secured to it; the pivot axes being located adjacent to, but at opposite sides of the mast. Springs are interposed in these links and also in the brace; in the latter they are provided at locations intermediate the center hull and the flanking hulls. This construction increases the self-righting ability of the vessel under the heeling influence of wind, making the structure stable throughout its heelable range.
