Abstract: In one example, a watercraft includes a buoyant body in the form of a single piece structure sized and configured to support the weight of one or more users. The watercraft also includes a retractable fin connected to a pin that resides in a fixed location relative to the body, the pin including a side surface that is in contact with the body. The retractable fin is rotatable about the pin between an extended position and a retracted position, and the retractable fin includes an engagement portion that is engageable with a first portion of the body and with a second portion of the body. The retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body.

Abstract: In one example, a board includes a body having a single piece structure, the body including an upper surface that defines a deck, and a lower surface. The board also includes first and second retractable fins, where the first retractable fin is rotatably connected directly to the body at a first fixed location on the body such that the first retractable fin is rotatable about the first fixed location between an extended position and a retracted position, and the first retractable fin including an engagement portion that is engageable with a first portion of the body and with a second portion of the body. The first retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the first retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body.

Abstract: In one example, a watercraft is provided that includes a body having a bow and a stern whose respective shapes are substantially different from each other. The body includes a hull, an open cockpit, a ramp that is located aft of the open cockpit and slopes downwardly toward the stern, where a lower end of the ramp is located near the stern, and a transom, where the lower end of the ramp extends through the transom.

Abstract: In one example, a board suitable for use in water sports includes a body that includes an upper surface and a lower surface. The board also includes a retractable fin connected to the body and configured to assume extended and retracted positions. In the extended position, a substantial portion of the retractable fin extends below the lower surface of the body, and in the retracted position, a substantial portion of the retractable fin resides within a recess at least partly defined by the body.

Abstract: In one example, a watercraft, such as a kayak, is provided that includes a body, at least a portion of the body having a unitary one-piece construction. The body includes a hull and a cockpit that is integral with the hull, and the cockpit includes a seating area. Finally, the example watercraft includes a backrest connected to the body near the seating area and rotatable between a substantially vertical orientation and a substantially horizontal orientation, and movement of the backrest is limited to rotational motion.

Abstract: In one example, a watercraft, such as a kayak, is provided that has a body which includes a hull, a cockpit connected with the hull, and a backrest removably attached to the body. The watercraft may additionally include a fish tail configuration near a stern of the watercraft.

Abstract: In one example, a watercraft is provided that includes a body. The body has a hull and a ramp that slopes downwardly toward a back of the hull. Additionally, a reverse chine geometry is incorporated in a portion of the bottom of the hull. Finally, one or more projections extend downward from the bottom of the hull.

Abstract: In one example, a paddleboard includes a body defining a fin housing within which a fin is partially received. The fin is configured to reside in the fin housing in either of a first operating position or a second operating position, where the second operating position is different from the first operating position. Finally, a fin retention element is provided that is configured to releasably secure the fin to the body.
