A house is provided. The house includes a base and a roof. The roof is attached to the base. The base has sufficient buoyancy to enable the house to float on water.

An apparatus for mounting a pedal propulsion system to a watercraft, having a mount portion configured to be attached to the watercraft, a link support, and upper and lower links pivotally connected to the link support and to the mount portion. The link support and upper and lower links are configured to form part of a four-bar linkage arrangement and to simultaneously move together between an extended and lockable, operable position for operating the propulsion system, and a retracted and lockable, stowed position elevated above the extended position, for loading, transporting, unloading and/or launching the watercraft in the water. A column clamp is configured for selectively fixing a drive column of the pedal propulsion system to the link support, wherein the drive column, the link support and the upper and lower links are configured to simultaneously move together between the extended and retracted positions.

A modular hybrid propulsion unit is disclosed that is mountable to a watercraft. According to an example, the modular hybrid propulsion unit includes a housing configured to fit within a complementary housing receiver on a topside of the watercraft, and a rotational output coupling configured to rotationally engage with a rotational input coupling for a propeller of the watercraft. The propulsion unit further includes an electric motor within the housing, the electric motor having a motor shaft connected to the rotational output coupling for providing an electrically powered rotational input to the rotational output coupling. The propulsion unit further includes a crank having one or more crank arms. The crank is connected to the rotational output coupling for providing a human powered rotational input to the rotational output coupling independent of the electrically powered rotational input by the electric motor.

A watercraft and associated pedal drive system are provided. The pedal drive system allows for unassisted manual pedaling to provide thrust to the watercraft. The pedal drive system also provides on demand pedal assistance of varying levels via an assist drive train having an electric motor to supplement the manual pedal force input provided by a user at the pedals of pedal drive system.

A house is provided. The house includes a base and a roof. The roof is attached to the base. The base has sufficient buoyancy to enable the house to float on water.

In one example, a watercraft includes a hull that defines a well extending through a bottom of the hull, and the hull defines an upper tray recess and a lower tray recess. A pedal-drive mechanism is connected to the hull and configured to assume both a stowed position and a deployed position, and a portion of the pedal-drive mechanism extends through the well when the pedal-drive mechanism is in the deployed position. A pedal-drive housing and attachment mechanism is provided that includes a tray configured to move between a forward position in which part of the tray resides in the lower tray recess, and an aft position in which part of the tray resides in the upper tray recess.

An electronic control module (46) for coupling a pedal mechanically powered electric generator (28) and a battery (44) to a motor controller (48) of a watercraft propulsion motor (32), comprising: an electrical input operatively connected to the generator (28); a processor with a memory having an output operatively connected to the motor controller (46), said processor being operationally selectable by a user to one of multiple modes so that the processor being is configured to: in a first mode, combine power from the generator (28) with power from the battery (44) to power the motor (32); in a second mode, combine power from the generator (28) with partial power from the battery (44) to power the motor (32); and in a third mode, transfer power from the generator (28) to charge the battery (44).

A system for providing solar power to a watercraft includes a hull having an outer surface, defining a recess extending inward and offset from the outer surface by a distance, and configured to float on water. The system further includes a solar panel configured to fit within the recess and having a thickness that is substantially equal to the distance such that an outer edge of the solar panel is substantially aligned with the outer surface of the hull.

Disclosed is a pedal drive system for use with a watercraft that facilitates propelling of the watercraft. The pedal drive system of the present invention is placed through an opening in the bottom of the watercraft and affixed to the body of the watercraft. The propeller is then attached to a drive shaft. The user provides mechanical input (e.g., rotational force) by rotating pedals of a pedal arrangement of the pedal drive system. The rotational force is transferred from the drive assembly through the gears to the drive shafts that rotates the propeller, thus driving the watercraft forward as well as backward.
