NOVELTY - The sailboat has fore spar (4A), port side mast assembly and starboard side mast assembly whose ends are pivotably attached together, such that assemblies rotate independently. A bow hull (2A), port side hull (2B) and starboard side hull (2C) are provided to form vertices of triangle and rotatable about respective vertical axis independent of other. A rudder and dagger board assembly (7) is attached to underside of central structural element (1), such that horizontal axis of board assembly defines direction in which sailboat travels. The assembly is rotatable independent of hulls.    USE - Multi hulled sailboat.    ADVANTAGE - Since the rudder and dagger board assembly is attached to underside of central structural element, horizontal axis of board assembly defines direction in which sailboat travels. Thus slight rotation in the rudder rotates the whole rudder dagger board assembly into the desired sailing direction when the rudder dagger board assembly is unlocked. Hence the helmsperson can have clear view in the sailing direction dictated by the rudder dagger board assembly orientation. The sailboat can make quicker change in sailing direction and the requirement for the whole space frame to rotate during tacking can be avoided. The thrust generated by twin sail sets is controlled by the relative position of the sails in each sail set, so that direction of sail thrust can be in the fore or aft direction of the sailboat. Thus the sailboat can be stopped from traveling in one direction and the direction of travel reversed again. The large distance between the hulls can yield footprint on the sea, so that the rocking of the space frame in rough water can be reduced. Thus the impact of large wave sea conditions on the potential disruption of the air flow can be prevented over the sails.
