An apparatus for towing a water sports performer including a first leg, a second leg, a header, and a tow-line-attachment structure. Each of the first leg and second leg is adapted for attachment to one of the port side of a centerline of a boat or the starboard side of a centerline of a boat. The header is capable of assuming a plurality of different header lengths, and includes a first header portion, a second header portion, a housing, and a locking mechanism. The housing connects the first header portion and the second header portion. The housing includes a first receiver configured to receive a second end of the first header portion at a plurality of different positions. The locking mechanism is configured to secure the second end of the first header portion to the housing in one of the plurality of different positions to set the header length.

A wake tower assembly for use with a watercraft, including an arch portion extending across a width of the watercraft, first and second pivoting structures coupled to first and second ends of the arch portion, the first and second pivoting structures configured to attach to port and starboard portions of the watercraft to facilitate rotational movement of the arch portion between a lowered position and an upright position, and a first locking mechanism provided to the first pivoting structure including a biased pin member configured to engage an opening of the first end such that when the arch portion is rotated from the lowered position to the upright position, a biasing force of the biased pin member causes the biased pin member to engage the opening to mechanically lock the arch portion in the upright position.

A vehicle for conveying a rider within a tubular track comprises a support portion for supporting the rider and a retaining body adapted to retain the support portion against an interior wall of the tubular track. The retaining body has a sliding surface for slidable engagement with the wall of the tubular track. The support portion and the retaining body have a vehicle axis of movement about which the vehicle may rotate within the tubular track. An apparatus for transporting a rider comprises a tubular track having an interior wall and at least one vehicle.

A floatation device may include a bow section and a tail section pivotally connected to the bow section by a kingpin assembly. The kingpin assembly may be configured to include a positive kingpin inclination angle or a negative inclination angle that determine the yaw direction of the floatation device. A user may control the tilt or roll of the floatation device to offset a yaw direction and maintain a straight line tracking course.

A hull assembly is configured to transport a human user in water. The hull assembly includes a bow, having a bow concave portion. A port hull is joined to the bow. The port hull is adopted to accommodate a first foot of a human user. A starboard hull is joined to the bow and offset from the port hull by the bow concave portion. The starboard hull is adapted to accommodate a second foot of the human user. When a first port hull weight varies from a second port hull weight, the first port hull vertically deflects relative to the second port hull to increase the balance and stability of the human user and increase maneuverability of the vessel.

An alerting device can be attached to one or more tow lines for towing a watersport participant via a watercraft. In some instances, the alerting device can be spaced from the watersport participant and the watercraft during use. The alerting device can be deployed automatically, such as when tension in the one or more tow lines is reduced due to the participant being downed in the water so as to no longer be towed.

A tow pylon assembly for a watercraft has a pylon, a base connected to a lower portion of the pylon, the base being configured for connecting the tow pylon assembly to the watercraft, a bollard connected to an upper portion of the pylon, the bollard being configured for attaching a tow rope to the tow pylon assembly, and an equipment holding assembly connected to the pylon. The equipment holding assembly has a resilient member connected to the pylon. The resilient member is configured for holding equipment between the resilient member and the pylon. A personal watercraft having a rear platform and the tow pylon assembly connected to the rear platform is also disclosed.

A personal bipedal watercraft includes a pair of skis. Each ski of the pair of skis includes a floating hull. A deck is secured to the hull. A binding on each deck is configured to receive a foot of a user. A plurality of paddle assemblies are moveably secured to an underside of the floating hull. The paddle assemblies each include a blade and a fin.

A surfboard core and a stringer array embedded in the core to modify handling characteristics of the board.

An apparatus may include a tower configured to be mounted to a boat. The apparatus may further include an actuation assembly, wherein the actuation assembly may include a linkage extending between a folding portion of the tower and at least one respective base for moving the tower between a first position and a second position.
