An oarlock-installation for a boat in which an oarlock is mounted on an upright pin for angular displacement about the pin during rowing of the boat, the oarlock-installation comprising a mechanism for deriving measurements of angular displacement of the oarlock from a datum angle about the pin during the rowing, a mechanism for deriving measurements of force exerted on the oarlock during the rowing, and a mechanism for deriving measurement of rowing power from the measurements of force and the measurements of angular displacement. The rowing-boat oarlock-installation may also comprises a power module, attached to the oarlock, which is responsive to rowing of the rowing-boat to derive force measurements in accordance with rowing forces exerted on the power module during the rowing.

A paddle mount for a boat is described. The mount includes a generally t-shaped tubular body including a flange and a stem, where the length of the flange and the stem is adjustable and the ends of the flange are configured to rest on opposite sides of the boat cockpit. The mount is configured to couple to the front end of the cockpit and to an end of the stem, such that the t-shaped body may be rotated upwards away from the boat. A mount adapter is also described that may be used to attach a paddle to the boat using the mount.

The invention involves a paddleboard kit for converting any water sports board such as a surfboard into a paddleboard. An oar support assembly, typically secures oars with pivotal paddles to the board; facilitating rowing exercises that may be practiced while kneeling or standing. During use, the pivotable paddles pivot in such a way that the blade portion holds a steady position in relation to a shaft portion on the power stroke, whilst being free to fold in the opposite sense on the idle stroke when each stroke is executed as a substantially axial thrust of the shaft. The oar support assembly secures the pair of oars and is itself secured to the board by way of board couplers adjustably coupled to a portion of a strap that tightens to snuggly wrap around the board.

A tri-hull fishing kayak includes a platform, an elevated seat, a foot operated paddle, and a triple hull including two side pontoons and one forward central pontoon having a front portion and a rear portion. The front portion, extending centrally from the platform, provides enhanced longitudinal stability. The two side pontoons are of a width and separation to provide enhanced lateral stability. The tri-hull fishing kayak reduces the need to frequently re-position the kayak when there is wind and/or current, thereby minimizing interruptions to fishing. The elevated seat is ergonomic for long-term sitting, and is high enough above the water to facilitate effective pitching and casting underhand, and to permit a steeper viewing angle into the water, thereby making sight fishing easier. The foot-operated paddle can be used to precisely steer the kayak, and therefore frees up the user's hands for fishing. Further, the platform enables fishing while standing.
