A towable watercraft including a body member having a tow-rope hitch coupled to a front portion thereof and first and second 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 between the stabilizing member may be retained about a circumferential portion of the body member, wherein first and second end portions of the first and second elongated stabilizing members having corresponding stirrups are laterally movable away from, and back toward, each other.

The present invention is used in water board sports but maybe of benefit to other water vessels; the present invention assists in the planing of water sport boards; the present invention was initially designed for windsurfing it can be used in surfing, kite-boarding and with other water crafts; the present invention uses one or more hybrid-fins, referred to as Squid-Fins™, along with a new base and fin-box that allows for more adjustments and easier swapping of fins; this system helps the board get up on a plane earlier and stay on that plane longer along with making it possible to add new characteristics to the performance of the board including hydro-foiling.

There is provided an assembleable aquaboard made of fiber-reinforced plastic (FRP), including: a first plate having a first T-shaped slot on the top surface and a second T-shaped slot on the right side surface, a second plate having a third T-shaped slot on the top surface and a fourth T-shaped slot on the right side surface; a third plate having a fifth T-shaped slot on the top surface, a sixth T-shaped slot on the right side surface; a fourth plate having a seventh T-shaped slot on the top surface and an eighth T-shaped slot on the left side surface; a first T-shaped connector to connect the first and the third plates; a second T-shaped to connect the second and the fourth plates; and a first I-beam connector to connect the first plate, the second, the third plate and the fourth plate to form the assembleable aquaboard.

A floatable apparatus includes a floatable body defining a longitudinal axis parallel with the length of the floatable body, a supporting member positioned under the floatable body for exerting a lifting force onto the floatable apparatus and a coupling assembly coupling the floatable body to the supporting member. The coupling assembly includes a base adapted to secure to the floatable body and a joint adapted to secure to the supporting member. The joint is detachably attached to the base and movable from a first position at which the joint is pivotable about and detachable from the base and a second position at which the joint abuts and is secured to the base. A coupling assembly for a floatable apparatus with a floatable body under which a supporting member is positioned for exerting a lifting force onto the floatable apparatus is also provided.

Wakeboats that include an aquatic invasive species control apparatus are provided. These wakeboats can include: a wakeboat with a hull; at least one throughhull fitting in the hull of the wakeboat; an irradiation chamber in fluid communication with the at least one throughhull fitting, the irradiation chamber having a radiation source; and at least one water destination aboard the wakeboat. Methods for irradiating invasive aquatic species aboard a wakeboat are also provided. The methods can include: receiving water from outside the wakeboat hull; and irradiating water aboard the wakeboat prior to discharging the water.
