Abstract
Abstract A boat having at least two separate, shape-retaining sections, each section including a transversely disposed, vertical wall, each wall including a top edge and a bottom edge, each bottom edge being coterminus with a bottom surface of the boat. One vertical wall includes a plurality of narrow, elongated, vertical, wedge-shaped slots, each slot having sides converging in a downward direction from the top of the vertical wall. Each slot terminates in a bottom end which is spaced from the bottom edge of the vertical wall. The other vertical wall includes a plurality of narrow, elongated, vertical, projecting wedges, each wedge having sides converging in a downward direction from the top of the wall. Each wedge terminates in a bottom tip, the tip being spaced from the bottom edge of the wall. The wedges cooperate with the slots to join the sections together in end-toend relationship such that the walls are held together contiguously to form a bulkhead in the boat. The tips of the wedges abut the bottom ends of the slots to serve as positive stops for joining the sections together in given relative vertical dispositions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
223 words
A boat comprising: a. at least two separate, shape-retaining sections; b. each section including a transversely disposed, vertical wall, each wall including a top edge and a bottom edge, said bottom edge being coterminus with a bottom surface of the boat; c. said vertical walls including means for connecting said sections together; d. said connecting means including a plurality of narrow, elongated, vertical wedge-shaped slots in one of said vertical walls, each slot having sides converging in a downward direction from the top of said one vertical wall; e. each slot terminating in a bottom end, said end being spaced from the bottom edge of Said one vertical wall; f. said connecting means also including a plurality of narrow, elongated, vertical, projecting wedges in the other of said walls, each wedge having sides converging in a downward direction from the top of said other wall; g. each wedge terminating in a bottom tip, said tip being spaced from the bottom edge of said other wall; h. said wedges cooperating with said slots to join said sections together in end-to-end relationship such that said walls are held together contiguously to form a bulkhead in said boat; i. said tips of said wedges abutting said bottom ends of said slots to serve as positive stops for joining said sections together in given relative vertical dispositions.
Claim 2
Dependent Claim
223 words
A boat comprising: a. at least two separate, shape-retaining sections; b. each section including a transversely disposed, vertical wall, each wall including a top edge and a bottom edge, said bottom edge being coterminus with a bottom surface of the boat; c. said vertical walls including means for connecting said sections together; d. said connecting means including a plurality of narrow, elongated, vertical wedge-shaped slots in one of said vertical walls, each slot having sides converging in a downward direction from the top of said one vertical wall; e. each slot terminating in a bottom end, said end being spaced from the bottom edge of Said one vertical wall; f. said connecting means also including a plurality of narrow, elongated, vertical, projecting wedges in the other of said walls, each wedge having sides converging in a downward direction from the top of said other wall; g. each wedge terminating in a bottom tip, said tip being spaced from the bottom edge of said other wall; h. said wedges cooperating with said slots to join said sections together in end-to-end relationship such that said walls are held together contiguously to form a bulkhead in said boat; i. said tips of said wedges abutting said bottom ends of said slots to serve as positive stops for joining said sections together in given relative vertical dispositions.
Claim 3
Dependent Claim
162 words
A boat as defined in claim 1 wherein: a. each slot is defined by a pair of adjacent, oppositely disposed internal side walls extending inwardly from said one vertical wall and by a narrow, internal face disposed in a plane parallel to said one vertical wall; b. each wedge is defined by a pair of adjacent, oppositely disposed external side walls extending outwardly from said other vertical wall and by an external face disposed in a plane parallel to said other vertical wall; c. said side walls and faces of said slots and wedges form dovetail connections; d. each vertical wall defines one end of each section and includes a flat surface comprising the major portion of said one end; and e. at least one wedge and mating slot being disposed entirely to one side of the centerline of the boat, and at least another wedge and mating slot being disposed entirely to the other side of the centerline of the boat.
