A modular bicycle and board apparatus having a buoyant board, a front wheel, a rear wheel and handlebars mountable and usable in a first configuration as a bicycle in which the buoyant board is the bicycle's frame and in a second configuration as a surfboard by changing the orientation of the front wheel and handlebars with 90 degrees with respect to the buoyant board, the surfboard being steerable from the handlebars.

A swim training apparatus in the form of a swimming kickboard with an adjustable flap. The base of the kickboard is constructed from a buoyant material, providing ample support to the user in water. The adjustable flap attached to the base is adjusted using a means that allows for the user to customize the flap's position between 0 and 90 degrees. This feature adds variation to workouts as it changes water resistance and buoyancy levels experienced by the user. A locking mechanism secures the adjustable flap at the chosen angle. Additional features may include an integrated handle in the buoyant base, a textured surface on the base for enhanced grip and the ability to detach the adjustable flap for easy maintenance or replacement. The method of use involves selecting the desired angle, properly securing it, and proceeding with the swimming or exercise session. It also provides the option of adjusting the angle during the swimming session and offering convenient storage with a flat or compact configuration.

A watercraft has a hull which, in the area of the deck, has a support on which parts of the upper body of a user can rest and where the user can hold on to handles. A flow channel is defined on the hull and a propelling screw is disposed in the flow channel. The flow channel has an intake port and, downstream of the propelling screw, a jet outlet in the stern area. A support body is disposed on the stern area in such a way that the support body extends the support by means of its support surface. In such a watercraft, a considerable increase in traveling speed can be achieved if provision is made for at least one sliding surface to be provided on the underside of the support body and for the support body to be rigidly connected to the hull.

A towable watercraft including a body member having a tow-rope hitch coupled to a front portion thereof and one or more elongated stabilizing members extending beyond an aft portion of the body member is disclosed. The stabilizing members may be coupled to the hitch or an intermediate portion retained about a circumferential portion of the body member, wherein an end portion of the one or more elongated stabilizing members having corresponding stirrups are laterally movable away from, and back toward, each other.
