Abstract

Abstract A paddle-driven watercraft formed as a single closed shell with a hull and deck. The seat-forming recess is bounded toward the rear by a rim and a central rise or prominence extends forwardly and upwardly to a level above the rise in the deck to define a pair of platforms forwardly of the seat on which the user can kneel, and at the forward ends of these platforms with respective footrests. The platforms are laterally unconfined outwardly so that the seat platforms and footrests prevent accumulation of water.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 245 words
A paddle-driven watercraft comprising a single elongated closed shell formed with a hull constituting an underside of said shell and a deck constituting an upper surface of said shell, said shell defining a bow at a front end thereof, said hull and said deck being elongated in a direction of travel of said watercraft, said hull being formed with: a downwardly open, rearwardly widening channel terminating at a stern of said shell and commencing at a location substantially midway of the length of said shell, and said channel subdividing said hull between said location and said stern into two rearwardy extending hull sections separated by said channel, said deck being formed with: a seat-forming recess bounded toward the stern by a raised rim and open forwardly toward said bow, a central dip immediately ahead of said seat-forming recess in the direction of said bow, p2 a central rise convexly curved upwardly from said dip forwardly to a level above said rim, a forwardly and downwardly inclined slope from said rise to said bow, a pair of laterally unconfined platforms upon which a user of the watercraft can kneel on opposite sides of said rise, and a respective upwardly and forwardly inclined footrest at an end of each of said platforms proximal to said bow, said footrests being formed on opposite sides of said central rise, said seat-forming recess, said platforms and said footrests being constructed and arranged to preclude collection of water on said deck.
Claim 2
Dependent Claim 245 words
A paddle-driven watercraft comprising a single elongated closed shell formed with a hull constituting an underside of said shell and a deck constituting an upper surface of said shell, said shell defining a bow at a front end thereof, said hull and said deck being elongated in a direction of travel of said watercraft, said hull being formed with: a downwardly open, rearwardly widening channel terminating at a stern of said shell and commencing at a location substantially midway of the length of said shell, and said channel subdividing said hull between said location and said stern into two rearwardy extending hull sections separated by said channel, said deck being formed with: a seat-forming recess bounded toward the stern by a raised rim and open forwardly toward said bow, a central dip immediately ahead of said seat-forming recess in the direction of said bow, p2 a central rise convexly curved upwardly from said dip forwardly to a level above said rim, a forwardly and downwardly inclined slope from said rise to said bow, a pair of laterally unconfined platforms upon which a user of the watercraft can kneel on opposite sides of said rise, and a respective upwardly and forwardly inclined footrest at an end of each of said platforms proximal to said bow, said footrests being formed on opposite sides of said central rise, said seat-forming recess, said platforms and said footrests being constructed and arranged to preclude collection of water on said deck.
