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.

Abstract: A lightweight collapsible trade show display case has a transparent showcase. The support legs are opposing rectangular side panels which are hinged to the base of the showcase. A single front facia panel slides into grooves of the support legs and locks in place thereby providing an extremely stable base. Assembly is accomplished in under a minute. A UPS suitable shipping container holds the sliding front facia panel and pre-assembled showcase.
