An energy efficient ship is achieved by powering the ship using at least one propulsion level, each propulsion level having large grids at the forward and stern ends of the ship and side channels incorporating turbines that move water through the ship, rather than around the ship, thereby substantially eliminating energy wasting wakes and cavitation.

A pedal assembly and steering assembly are disclosed for converting an inflatable, drop stitch paddle watercraft into a pedal watercraft. The pedal assembly includes a mounting plate and mounting bracket for supporting a geared drive shaft in an opening extending through the floor of the watercraft. The steering assembly includes a rudder connected to a tiller through push pull cables.

A support for inclusion internally within a plastic boat body to structurally reinforce the plastic boat body is provided. The support may comprise a support plate and a support brace. Also provided is a reinforced component for a plastic boat body, comprising an interior support; and one or more plastic exterior walls. Plastic boats comprising supports and reinforced components are also provided. Further provided are associated kits, systems, and methods.

A stern operatively mounted universal transducer for boat includes a mounting device, having upper and lower brackets, for securement to the boat, preferably its transom, the upper and lower brackets secure a drive cylinder, which when operative, lowers a drive rod for shifting a sonic transducer upwardly above the water, or downwardly into the water to scope the surrounding underwater typography. A pair of guide rods shiftably extend through the upper and lower brackets, and at their upper ends, secure to a motor and gear housing, the guide rods at their lower ends secure to a base plate. A transducer shaft extends into the motor housing which provides for its pivoting, and at its lower end, extends downwardly through the base plate, and secures a transducer mounting plate, to which the transducer is affixed, in preparation for its usage. Electrical, pneumatic, or hydraulic pressure can be used to pivot the transducer shaft, and to raise and lower the base plate that connects with the drive shaft, the latter when operative, raises or lowers the entire transducer assembly into and out of the water, during application.
