Abstract: A personal watercraft is disclosed comprising a pair of longitudinally connected pontoons suitable for supporting a user on the surface of a body of water. A slip-joint comprising a pair of concentric cylinders, one attached to each pontoon, provides desired lateral fixation between the pontoons while allowing relative longitudinal movement. Floating outriggers are provided to enhance the stability of the watercraft, and a set of hand rails helps the user balance on and operate the device. Paddle elements can be provided on the bottom surface of each pontoon to allow the user to operate the watercraft by using a striding motion similar to that used when cross-country skiing. The watercraft may have a rudder to help steer the craft, and it may also have a removable seat. A sail option is also provided. The pieces of the watercraft are removably connected to allow quick and easy assembly and disassembly, for transport to and from the water.

Abstract: A game of two players using paddles to hit a ball against a roof. The roof has a pitch of approximately 6/12 with a front edge approximately eight feet above ground level. The roof having a length of approximately 50 feet and a height of approximately 25 feet. The roof must have either no gutters or have covers on the gutters. The serving player must stand approximately 12 feet from the front edge of the roof, and must hit the ball on one bounce while the returning player has up to three bounces to return the ball from any location. The game has foul out of bound shots if the ball bounces over the left roof edge, over the upper rear edge, and over the right edge of the roof. Additional foul shots are if the ball first lands on an edge or covered gutter of the roof on first bounce. Another foul is if either player extends their paddle over an edge of the roof at any time. A still another foul is if a player interferes with the other player by standing in front of the player whose turn is to hit the ball.
