Abstract
Abstract A sectional boat comprised of two detachable sections secured together in longitudinal alignment by interlocking means in a fluid tight relation. Each section comprises a bottom wall, a front wall, a rear wall and tapered side walls to form a selfcontained buoyant unit. The side wall of each section are inclined outwardly at an angle relative to the longitudinal axis of the section in diverging relation from front to rear. The rear section is slightly larger than the front section and can be inverted over the front section in a nested relation to form an enclosed compact unit for convenient storage and transportation. Interlocking means in the form of bolts and nuts are employed to connect adjacent end walls of the sections together to form a boat of desired length.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
248 words
A sectional boat comprising: a first section and a second section adapted to be connected together in longitudinal alignment to form a boat; each of said sections having a bottom wall, a front wall, a rear wall, and a pair of vertically straight side walls inclined outwardly at an angle relative to a longitudinal axis passing through the respective sections whereby said side walls form a pair of opposite, substantially continuous tapered side walls extending lengthwise of said boat in a diverging relation from front to rear thereof when said sections are connected together in longitudinal alignment; said second section being larger than said first section and invertable over said first section in a nested relation to close the open upper end of said first section and form a compact package for storage and transport; said second section side walls surrounding said first section side walls in said nested relation; means detachably connecting said second section front wall to said first seCtion rear wall in an abutting, fluid tight relation to form a multiple section boat; and reinforcement means including a pair of vertically spaced reinforcement bars secured to each side wall of each section at the bottom thereof and adjacent the top thereof, respectively; a plurality of laterally spaced channel members extending lengthwise of each section and secured to the bottom wall thereof; and a vertically extending reinforcement bar secured to each corner formed at the first section rear wall and the second section front wall, respectively.
Claim 2
Dependent Claim
248 words
A sectional boat comprising: a first section and a second section adapted to be connected together in longitudinal alignment to form a boat; each of said sections having a bottom wall, a front wall, a rear wall, and a pair of vertically straight side walls inclined outwardly at an angle relative to a longitudinal axis passing through the respective sections whereby said side walls form a pair of opposite, substantially continuous tapered side walls extending lengthwise of said boat in a diverging relation from front to rear thereof when said sections are connected together in longitudinal alignment; said second section being larger than said first section and invertable over said first section in a nested relation to close the open upper end of said first section and form a compact package for storage and transport; said second section side walls surrounding said first section side walls in said nested relation; means detachably connecting said second section front wall to said first seCtion rear wall in an abutting, fluid tight relation to form a multiple section boat; and reinforcement means including a pair of vertically spaced reinforcement bars secured to each side wall of each section at the bottom thereof and adjacent the top thereof, respectively; a plurality of laterally spaced channel members extending lengthwise of each section and secured to the bottom wall thereof; and a vertically extending reinforcement bar secured to each corner formed at the first section rear wall and the second section front wall, respectively.
Claim 3
Dependent Claim
58 words
A sectional boat according to claim 1 wherein said connecting means comprises a plurality of bolts extending through aligned openings formed in said first section rear wall and said second section front wall; and sealing means interposed between said front and rear walls about at least those of said bolts located below the water line of said boat.
Claim 4
Dependent Claim
24 words
A sectional boat according to claim 1 including a removable seat extending transversely of said sections across and overlying said front and rear walls.
