An oar apparatus configured to remain submerged under water during the power stroke and the return stroke. The oar apparatus has a sheath and a shaft rotationally disposed within the sheath. An oar blade is affixed to the shaft, such that the oar blade is rotational relative to the sheath. The oar blade has a deployed orientation, in which the oar blade is substantially perpendicular to the movement direction of the vessel, and a feathered configuration, in which the oar blade is substantially parallel to the movement direction of the vessel. The oar blade is asymmetrical relative to the center axis of the shaft, such that resistance of the water exerted onto the oar blade creates a first moment urging the oar blade into the deployed orientation during the power stroke and a second moment urging the oar blade into the feathered orientation on the return stroke.

A handle for carrying watercraft, wherein the handle also functions to securely retain a paddle or oar, the handle comprising a channel for receiving and retaining a paddle or oar using an interference fit. The handle is secured to the watercraft by a strap attached to the watercraft body and passing through a slot in the handle that runs parallel to the channel.

A rigid or inflatable stand up paddleboard (SUP) conversion kit to provide a stable recreational platform for fishing. diving, hunting, nature photography, birdwatching or other activity. A detachable frame positions a pair of pontoons rearward relative to the SUP to avoid interference with rowing. A rolling storage case stores activity accessories such as diving or fishing equipment. After securing the storage case to the SUP, the case serves as a storage seat. A rear canopy frame may be assembled onto the SUP in order to support a rear canopy to conceal the user; and a front canopy frame may assembled onto the SUP in order to provide additional concealment that may be used for a hunting dog. The various conversion kits are compact and self-contained, and can fit easily in the trunk of a car.
