A device comprises a spring and a sleeve. The spring is configured to form a closed loop. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The spring defines a circumference while in the uncoiled configuration. The spring is disposed within the sleeve.

A personal watercraft has a hull and a deck. The hull defines at least in part a tunnel. A ride plate is connected to the hull and defines a bottom wall of the tunnel. The personal watercraft also has a motor, a jet propulsion system disposed at least in part in the tunnel, and a steering assembly. The deck has a pedestal, left and right gunnels, left and right foot-wells disposed laterally between the pedestal and their respective gunnel, and a rear platform. A straddle seat is disposed on the pedestal. Left and right footrests have left and right standing surfaces facing substantially forward and extending at least partially forward of the tunnel. The left footrest extends laterally between the pedestal and the left gunnel. The right footrest extends laterally between the pedestal and the right gunnel.

A hull assembly is configured to accommodate propulsion in at least two directions at once. The hull assembly includes a dual bow board further comprising a first bow and a second bow with an insert box therebetween. The insert box travels through the dual bow board from a top side to a bottom side.

A multi-purpose personal watercraft for deployment in different configurations as desired by a user. The multi-purpose personal watercraft comprises a base frame which forms a watercraft base which includes side extensions, an aft floor board, and a bow portion, as well as two opposing mirror image side floats with which the base frame is selectively integrated. When in place, the opposing side floats form the multi-purpose personal watercraft's U shaped hull and enable the selective attachment of a rudder assembly behind the multi-purpose personal watercraft's stern. With respect to propulsion, base frame is configured to enable the selective deployment of pedal propellers, a user's legs, or a trolling motor. A dual steering system enables the control of up to two discrete steering mechanisms from a single position on the watercraft.

A personal watercraft comprises a body; a driving power source mounted in the body; a water jet pump driven by the driving power source to eject a water jet in a rearward direction; a handle bar gripped by a rider; a rider operation member provided on the handle bar, the rider operation member being operated by the rider to be movable to an acceleration position for providing a forward movement command, a deceleration position for providing a rearward movement command, and a neutral position for providing an idling command, the neutral position being set to a position between the acceleration position and the deceleration position in a movement path of the rider operation member; and a control unit which controls the driving power source in response to the rider's operation for moving the rider operation member.

A board paddling training apparatus for assisting in improving a user's paddling technique and strength. In particular, the board paddling training apparatus includes a buoyant board, such as a board adapted for surfing, bodyboarding, paddleboarding, or other board-related sport that entails paddling, and includes a resistance mechanism that creates drag or resistance against a user's paddle stroke. Some implementations of the resistance mechanism can be adjustable in order to create a variety of resistance against the user's paddle stroke and board movement.

A water pad assembly adapted to floatingly support a human in open water, including: a water pad member and a plurality of grommets and/or cup holders.

The subject invention relates to a method for affixing two or more structures to be used in connection with a floating dock, stationary dock, gang plank, swim platform, or the like. The subject invention more specifically discloses a deck structure which is comprised of one or more sections which are adapted to be interconnected, wherein said sections are comprised of a frame, and a deck, wherein the frame is comprised of a first box-channel on a first side of the frame, a second box-channel on the second side of the frame, and at least two self-squaring cross braces, wherein the self-squaring cross braces are attached to both the first side and the second side of the frame, and wherein the deck is attached to the top side of the frame.

This invention relates to recreational flotation devices, and particularly to floating mattresses or lounges, and to a method for manufacturing same.

The present application is directed to a flotation device for use in aquatic physical therapy. The flotation device preferably comprises side portions that wholly or partly surround the user, and permit the user's elbow(s) and/or forearms to rest upon and be supported thereby. The flotation device also preferably has at least one handgrip permitting the user to easily hold onto and be supported by the flotation device. Additionally, the present invention comprises methods of making and using such a flotation device.
