Boat hull construction

Claim 2

A boat comprising: a. a hull of two juxtaposed hollow sections, each section including a plate and an enclosing body portion, the plate being essentially flat and longitudinally extending as a side of the section across the body portion to form a hollow member or section therewith; b. struts interconnectingly mounted fore and aft on each of the hollow sections and essentially at right angles to the plates to dispose the plates relatively proximate and substantially parallel to Each other; and c. gear means including interconnected fore and aft arrangements of a hollow parallel guide into which a strut from each hollow section telescopingly is adapted to move and means for relatively moving and constraining the struts within the guides comprising a fore and aft gear box mounted on the guides and containing a pinion gear, each strut disposing a rack along one margin which engages the pinion gear, and link means for connecting the fore and aft gear boxes whereby rotation of one pinion gear transmits rotation to the other pinion gear and relative movement of the fore and aft struts and hollow sections whereby the sections may be selectively disposed in adjacent juxtaposition or separated at will.

Claim 3

A boat comprising: a. a hull of two juxtaposed hollow sections, each section including a plate and an enclosing body portion, the plate being essentially flat and longitudinally extending as a side of the section across the body portion to form a hollow member or section therewith; b. struts interconnectingly mounted on each of the hollow sections to dispose the plates relatively proximate and substantially parallel to each other; c. gear means including connection means interconnecting the hollow sections whereby relative movement of the gear means imparts relative movement to the hollow sections whereby the sections may be selectively disposed in adjacent juxtaposition or separated at will; and d. a central rigid deck portion mounted over the struts, a pair of interfolding deck members hingably mounted between longitudinal margins of the rigid deck portion and the margin of each hollow section, whereby, when the hollow sections are disposed to their fullest extent, the interfolding deck members extend into the same plane as the rigid deck portion to form a deck, and when the hollow sections are in juxtaposition the interfolding deck members are disposed essentially vertically and surmounting the margins of the hollow section.

Claim 4
