This invention pertains to paddles such as canoe paddles in which the angular relationship between the paddle handle and paddle blade can be adjusted. With respect to the paddle handle the blade orientation can be straight or angled and locked with an adjustable swivel joint.

A self-propelling watercraft system is provided. The watercraft has a base with a plurality of sidewalls extending from the base to form a cockpit. The base also has a recess, where a pump can detachably connect to the hull within the recess. The pump has an intake valve on a first end and a nozzle on a second end that is opposite the first end. The intake valve can intake water. The nozzle can jettison water received in the pump from the intake valve and agitate water surrounding the nozzle.

An inflatable standup paddleboard having a split deck pad. The split deck pad may allow for easier storage and greater customization options for the inflatable standup paddleboard. The split deck pad may also be removable from the body of the standup paddleboard through integral grooves within the body of the inflatable standup paddleboard. The structural integrity and buoyancy may be further improved with a crisscrossed structure of strings within the interior of the inflatable standup paddleboard.

The invention relates to an interface for mounting a propulsion mechanism to a watercraft such as a fishing kayak, and to a watercraft comprising such an interface. The interface comprises a first portion including a first plate with a hole sized and shaped for receiving therethrough a portion of the propulsion mechanism, a second portion including a second plate and one channel extending from the second plate, the channel being in registry with the hole of the first portion for therein a portion of the propulsion mechanism. The interface also comprises fastening assemblies for removably fastening the second portion to the first portion of the interface, and a guiding assembly for maintaining the channel of the second portion in registry with the hole of the first portion.

The present invention disclosed a paddle, which includes a blade and a hollow lower shaft that connects to the blade. The hollow lower shaft is capable of receiving a rod and an upper shaft capable of entering and moving within said lower shaft; with one end of the upper shaft connected to the rod and able to move simultaneously with the upper shaft within the lower shaft. Wherein, the material of the rod within the hollow lower shaft is different from that of the hollow lower shaft, and the paddle is less likely to break instantaneously.

Disclosed herein is a multifunctional stand-up paddleboard (MFSUP) comprising a paddleboard, a paddle, and a drive unit. At the stem of the paddleboard is a docking port configured to receive the drive unit that propels the paddleboard. In some embodiments, the paddleboard comprises a rigid midsection, and an inflatable bow and stem. The inflatable portions are inflated during use and deflated then folded over the midsection during storage. A control paddle having control switches send command signals by Bluetooth to the drive unit to control the velocity of propellors. A battery bank is disposed on the midsection and provides power to the drive unit. A solar panel can be included on a superior surface of the paddleboard to supply power to the battery bank. The drive unit is removable from the docking port for propelling a human through a water body. Other features and methods are also disclosed.
