ABSTRACT:
A variable width boat includes a plurality of hulls and a width varying arrangement connected to and between the hulls for selectively moving the hulls between a closed, folded position and an extended, unfolded position in which the hulls are laterally spaced apart from one another. The variable width arrangement maintains the hulls in an upright, longitudinally fixed, substantially parallel relationship as the hulls are moved laterally between the closed and extended positions. In another aspect of the invention, a mast for use in a sailboat includes a mast assembly having a plurality of telescoping mast sections. The mast sections are arranged to collapse telescopically to permit the height of the mast to be reduced. The mast also includes a mast raising arrangement for raising and lowering the mast. In one preferred embodiment, the mast further includes a plurality of profiled sail supporting ribs each having a peripheral edge. The sail supporting ribs are connected to the upper end of an associated one of the mast sections and a covering is connected to the peripheral edge of the plurality of sail supporting ribs such that the sail supporting ribs and covering cooperate to form a wing shaped sail surface when the mast is in the raised position and the covering folds accordion style when the mast is in the lowered position.
