Abstract: A watercraft kit includes a watercraft and a buoyant removable rear extension optionally connected to a rear of the watercraft. The watercraft includes a hull having a transom and a deck disposed above the hull. The deck is supported by the hull. A propulsion system is operatively connected to an engine for expelling a stream of water rearward of the transom to propel the watercraft. When the removable extension is connected to the rear of the watercraft, the removable rear extension is disposed at least in part rearwardly of the transom. The removable rear extension defines a longitudinal channel. When the removable extension is connected to the rear of the watercraft, the channel receives at least one of at least a portion of the propulsion system, and at least a portion of the stream of water flowing therethrough when the propulsion system is operating to propel the watercraft forwardly.

Abstract: A watercraft has a hull having a bow, a deck disposed on the hull, an engine connected to the hull, a propulsion system operatively connected to the engine, a first bow sponson disposed on a starboard side of the bow, and a second bow sponson disposed on a port side of the bow. A sponson suitable for use on a bow of a watercraft is also disclosed.

Abstract: A sponson for a watercraft has a sponson body having a front end, a rear end, a top edge and a bottom edge, and a vane connected to a side of the sponson body and extending away therefrom. The vane has a front end and a rear end. The front end of the vane is disposed closer to the bottom edge of the sponson than the rear end of the vane. A watercraft having sponsons of this type is also disclosed.

Abstract: A boat has a hull and a deck is disposed on the hull. A tower is connected to the deck. The tower has a top. The top has at least one storage compartment defined therein. A canopy is connected to the top, the canopy has at least one frame member and a canvas connected to the at least one frame member. The canopy has an extended position and a retracted position. The canvas and the at least one frame member are disposed at least in part in the storage compartment of the top when the canopy is in the retracted position. A boat having a tower with a top and a canopy attached thereto is also disclosed where the tower is movable between a first position and a second position.

Abstract: A watercraft has a hull having a bow, a deck disposed on the hull, an engine connected to the hull, a propulsion system operatively connected to the engine, a first bow sponson disposed on a starboard side of the bow, and a second bow sponson disposed on a port side of the bow. A sponson suitable for use on a bow of a watercraft is also disclosed.

Abstract: A straddle seat has a top portion having a rear portion and a front portion. Two side portions extend downwardly from the top portion. The front portion extends upwardly and forwardly from the rear portion. The front portion is hourglass shaped and has a narrowing. The front portion has a pair of lateral wings extending laterally outwardly above at least part of the two side portions for covering at least in part knees and thighs of a driver. A personal watercraft having such a straddle seat is also described. The personal watercraft has a helm assembly and footrests having middle sections disposed rearwardly of the helm assembly. Front sections extend upwardly and forwardly from the middle sections forming a first angle. Rear sections extend upwardly and rearwardly from the middle sections forming a second angle. The first angle is greater than the second angle.

Abstract: A boat coverable by a flexible cover has a hull, a deck, and a tower movably connected to the deck. The tower has a central structure. The tower is movable between a first position and a second position. The deck is coverable by the flexible cover when the tower is in the second position such that the flexible cover is associated with at least a portion of the central structure. The portion of the central structure is movable to a third position vertically intermediate positions of the central structure in the first and second positions of the tower to tension the cover. A boat having a flexible cover connected to the central structure of the tower and a method of a method of installing a flexible cover on a boat are also disclosed.

Abstract: A hull for a watercraft has a port side, a starboard side, and a keel disposed between the port side and the starboard side. Each of the port and starboard sides has a first portion having a first deadrise angle, and a second portion having a second deadrise angle. The first portion is disposed laterally between the second portion and the keel. A first chine is connected to the first portion. The first portion is disposed laterally between the keel and the first chine. A second chine is connected to the second portion. The second portion is disposed laterally between the first chine and the second chine. The second chine is a soft chine. The first chine has a smaller radius of curvature than the second chine.

Abstract: A personal watercraft is disclosed having a hull and a sub-deck disposed on the hull. The hull and sub-deck together form a hull and sub-deck (HSD) assembly. An engine is disposed in the HSD assembly. A propulsion system is connected to the hull and operatively connected to the engine. A deck is disposed above the sub-deck. The deck has a pedestal.
