ABSTRACT:
A sailboat of the catamaran type has a pair of hulls joined by a pair of wedge shaped crossbeams, the crossbeams geometry being oriented to provide balanced distribution of loading on the hulls and crossbeams. An easily dismantable, multipart mast is stepped on the forward crossbeam and has a hook engaged by a ring or the like which is coupled to the shrouds and stay cables. The opposited ends of these cables has a unique "T" member for quick coupling with slotted shroud and stay anchor plates on the hulls of the boat. The rudder assembly includes an extruded rudder blade mounted in a rudder guide for vertical movement such that it is automatically raised upon encountering an obstruction.
