A boat and a propeller assembly for a boat. The propeller assembly includes a propeller and a thrust bearing, and the thrust bearing is made of a harder material than the propeller. The boat may also include a hull, a drive shaft, and a motor. The motor may be positioned within the hull and configured to rotate the drive shaft. The drive shaft may extend through a hull bottom of the hull and the propeller assembly may be positioned forward of a transom of the hull and beneath the hull bottom. The propeller may include a central hub having a hole capable of having the drive shaft inserted therethrough. The thrust bearing may be located in the hole of the central hub and secured to the propeller such that the thrust bearing and the propeller form a unified assembly.

A boat, having a stern, includes one or more inclined seats. Each inclined seat includes a seat bottom that is inclined at a downward angle in a direction extending from aft to fore and a seat back. The inclined seat may be movable to allow access to a compartment associated with the inclined seat. The inclined seat may be an aft-facing seat. The inclined seat may also include a headrest positioned above an upper portion of the seatback.

One or more propulsion arrangements for water vessels, and in particular propulsion arrangements that include flanking rudders with bidirectional high-lift sections to improve performance, particularly in the reverse direction. The flanking rudders are positioned adjacent a propulsor for directing a slipstream flow when the vessel is travelling in the reverse direction. Each flanking rudder has an elongated profile extending from a first edge to a second edge, and in which each elongated profile has a first bulb portion, a convex middle portion, and a second bulb portion.

In one example, a watercraft includes a hull that defines a well extending through a bottom of the hull, a pedal-drive mechanism connected to the hull, and the pedal-drive mechanism is movable, while connected to the hull, out of the well from a deployed position to a stowed position, and a mechanism that is configured to cover a portion of the well when the pedal-drive mechanism is in the deployed position.

A propulsion system for a seagoing vessel includes a rotatable frame and either (a) at least two masts coupled to the frame and each having a sail and a boom, or (b) at least two blades coupled to the frame. The rotatable frame and either the rotatable boom or at least two blades may be locked in position in a locked mode and unlocked and freely rotatable in an unlocked mode. A control system that is in communication in communication with a frame lock and either a boom lock or a blade lock and may be configured to determine when the vertical axis wind turbine should be in either the locked mode or the unlocked mode based on the direction of the wind and a direction that the seagoing vessel is traveling.

An underwater propulsion unit is provided for an outboard motor or a pod drive. The underwater propulsion unit includes a plastic housing designed for water to flow around, and a metal housing in which an electrical drive is received. The electrical drive is received in the metal housing so as to be sealed off from the surroundings in a watertight manner, and the metal housing is arranged inside the plastic housing.
