ABSTRACT:
Proa sailing vessel including a pair of spaced hulls comprising a windward and a leeward hull, a crossbeam assembly interconnecting the hulls and a fixed mast assembly with its lower end supported on the crossbeam intermediate the hulls and being inclined athwartship so that its upper end is disposed substantially vertically above the windward hull. The mast assembly is supported by a rigging arrangement which includes a standing stay extending between the upper end portion of the mast assembly and the windward side of the proa and a pair of pivot stays extending from an elevated pivotable mounting on the upper end portion of the mast assembly to respective opposite ends of a first boom connected through a lower pivotable mounting disposed intermediate the respective opposite ends to the leeward side of the proa. In this way, the pivot stays may be pivoted with the boom between respective opposing longitudinal positions at opposite sides of a pivot axis extending between the elevated and lower pivotable mountings whereby one of the pivot stays constitutes a forestay along which the sail may be hoisted.
