An air inflatable watercraft, preferably having a bow and stern, and having a cockpit, a bottom area forming part of said cockpit having a through opening therein adapted to receive a human operated propulsion mechanism which can be operated from the cockpit to propel the watercraft.

An air inflatable watercraft having an inflatable, airtight bow and stern, and having a bottom area between two side inflatable, airtight compartments which run essentially the length of the watercraft, upon inflation the two side compartments at least partially extend above the bottom to provide a cockpit therebetween, and the inflated bow and stern form a configuration which is adapted to be efficiently propelled, viz., adapted to cut through the water. This embodiment can be hand rowed or provided with a pedaled propulsion mechanism provided a through opening is built into the bottom.

An air inflatable watercraft having a bow and stern and having a central airtight compartment and two side airtight compartments running essentially the length of the watercraft, upon inflation the central compartment forms the bottom, stern and bow, and the two side compartments at least partially extend above the bottom to provide a cockpit therebetween. The central compartment has a through opening adapted to receive a human operated propulsion mechanism.

A system (12) for providing information to a rower of a boat (10). The system includes a display unit (32) adapted to be coupled to the boat for displaying information to the rower and an imaging device (36) in communication with the display unit. The imaging device is adapted to be coupled to the boat for capturing images and relaying the captured images to the display unit for display and viewing by the rower.

A plastic molded, sit-on-top kayak of unique size and shape is disclosed with various components which provide multi-purpose usage. the kayak is especially useful for multi-purposes such as sailing kayak surfing, scuba diving, paddling, touring and electric motorized usage. The kayak has attachment points integrally molded that provide for these multi-purposes. An important component of the invention includes a removable backrest that additionally provides secure waterproof storage of the operator's personal items. The backrest can be easily removed and reattached securely in place when desired. The ability to easily remove a backrest or backpack option also enables a desirable compact capability for transportation and storage by a user. Additional benefits of this feature provide for a smaller profile for packaging and commercial transportation. The kayak as disclosed may be formed for the most part, typically by blow molding, rotational molding, injection molding, rim molding, fiberglass and thermoforming, and by using a wide variety of polymer materials that may be suitable.

Improvements to electrically powered watercraft including kayaks are disclosed. The watercraft comprises a hull defining a cavity and a battery powered retractable propulsion unit. The retractable propulsion unit can be retracted into the cavity with powered or unpowered means. Various retractable propulsion units are disclosed, including propulsion units that are steerable wherein the thrust can be selectively directed. Specific embodiments to improve the steerability of electrically powered watercraft are disclosed. Mechanisms for disengaging the steering controls from the retractable propulsion units are also disclosed. Locking mechanisms for locking the retractable propulsion unit in an extended or fully retracted position are also disclosed.

A collapsible watercraft is comprised of a single high-strength foldable panel to fold into the form of a kayak with integrally defined keel, hull, sides, and deck. Using a single sheet of high strength panel creased in a predetermined pattern to form living hinges, the panel may be folded and transformed from self-defined compact knocked down package, into a rigid three dimensional tubular manifold in a kayak form that is optimized for performance in the water. Other removable rigid structural members, primarily a cockpit rim, rib, and floorboards help maintain the shape and integrity of the shell.

A personal boat carrying apparatus is provided for supporting a kayak or similar boat on a user during a portage to make portaging a kayak easier and less uncomfortable. The apparatus is lightweight but durable and has a body with a curved and arched center portion for resting on the shoulders of a user carrying the kayak, and two opposite body ends. Each body end has a support arm which pivots from a closed position to one or more open positions. The pivoting support arm provides multiple open positions to allow the apparatus to support kayaks and similar boats of different widths and configurations. Each support may have a swiveling bracket for engaging the gunwale of the cockpit of the kayak or similar boat. When the support arms are in the closed position, the apparatus may be compactly stored in the boat or elsewhere.

A pedal-powered kayak, the present invention offers a more rounded keel and stem which operates in the water leaving no or little wake in the front or the rear of the boat. Since little water passes into the boat there no rough ride. The hull further provides a pair of fullers integrally formed on hull and extending along each side of the hull from said keel to said stem to provide a greater wetting surface for the hull as kayak moves over a body of water. The hull also provides a pair of strakes for lifting the hull as the kayak increases speed over the water.

An improved thermoplastic kayak or canoe including a thermoplastic hull having an opening and a coaming integral with the hull and bordering the opening and including an outer and inner walls, the inner wall spaced apart from the outer wall, and at least one support bridge extending between the inner wall to the outer wall of the coaming.

Provided are systems and methods for an exercise mechanism including: a base for a user to sit or stand on; a track arranged near the base; at least one handle bar comprising a handle and a paddle blade attached to the track so as to allow sliding movement alongside the track; and a resistance mechanism to provide resistance as the user moves the handle bar in a selected motion depending on the user's exercise goals.

One aspect of the invention relates to a building or component kit intended for constructing different variations of vehicles. The kit includes a number of connecting members as well as unique modules; for example, wheel modules, which includes a carrier (6) with elements (17) for holding a wheel or some other kind of running member (7), as well as a number of sockets (12, 13) for receiving connecting members (4), in which sockets the connecting members can be disengageably applied. Another aspect of the invention relates to the wheel module as such.

A powered watercraft system including a watercraft body, a propulsion system, a sensor configured to measure a value indicative of a manually-generated time-variable first propulsive force resulting from a body motion of the user to move the watercraft body, and a controller configured control the propulsion system to generate a second propulsive force for powering the watercraft body based on the value indicative of the first propulsive force, the generated second propulsive force being at least partially contemporary with the first propulsive force.
