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.

The invention relates to a watercraft (10) having a hull which, in the area of the deck (13), has a support on which parts of the upper body of a user can rest and where the user can hold on to handles (20) preferably disposed in the bow area (11), wherein a flow channel (40) is assigned to the hull or the hull has a flow channel (40), wherein a propelling screw (41) is disposed in the flow channel (40), wherein the flow channel (40) has an intake port (33) and, downstream of the propelling screw (41), a jet outlet (43) in the stern area (12), and wherein a support body (50) is disposed on the stern area (12) in such a way that the support body (50) extends the support by means of its support surface (51). In such a watercraft, a considerable increase in traveling speed can be achieved if provision is made for at least one sliding surface (56) to be provided on the underside of the support body (50) and for the support body (50) to be rigidly connected to the hull.

A drag-inducing mat includes a main body configured to accommodate a rider. The main body includes a rider surface configured to face the rider and an opposing surface configured to face a slide surface. The drag-inducing mat also includes a sipe array defined within the opposing surface. The sipe array includes a plurality of sipes that extends from a first lateral edge of the main body to a second lateral edge of the main body to selectively induce friction between the main body and the slide surface based on force applied to the sipe array by the rider.

The invention relates to a water board (2) made of a material that can float on water, having a support area (8), on which a user rests at least partially. To reduce the current forces acting on the user while holding on to and being towed behind a motorized watercraft (24), it is proposed that the water board (2) has, at a front-end area, an attachment segment (22) for the articulation of the water board (2) to the watercraft (24).

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.
