Method of overshoot for faster planing of marine vessel
A method of planing a marine vessel propelled by an electric propulsion system operably connected to a rotatable propeller system including that a command input requesting an increase in throttle is received. The method also includes that it is determined whether the marine vessel is on plane and whether there is sufficient power and energy available in the electric propulsion system to reach planing speed when the marine vessel is not on plane. The method further includes that power output from the electric propulsion system is increased for a selected period of time such that the electric propulsion system is allowed to overshoot continuous power limits of one or more components of the electric propulsion system for the selected amount of time. The one or more components of the electric propulsion system including at least one of an electric motor, an energy storage device, and an electric controller.
STEERING MECHANISM FOR A BOAT HAVING A PLANING HULL
A boat includes a planing hull, a propeller, a main rudder, and a pair of flanking rudders. The planing hull has port and starboard sides, a transom, a hull bottom, and a centerline running down the middle of the boat, halfway between the port and starboard sides. The propeller is positioned forward of the transom and beneath the hull bottom. The main rudder is positioned aft of the propeller. The main rudder has a rotation axis about which the main rudder rotates. The flanking rudders are positioned forward of the propeller. One of the flanking rudders is positioned on the port side of the centerline, and the other flanking rudder is positioned on the starboard side of the centerline.

Marine vessel hull having profiled propulsor pod mounting surface
A vessel hull for an inboard-powered marine vessel includes a hull body having a hull bottom that includes a contoured pod mounting surface positioned longitudinally between a central keel and a stern of the hull body. The contoured pod mounting surface has a planar mounting face, for mounting a propulsor pod, and a transition face each positioned between peripheral edges of the pod mounting surface. The transition face slopes forwardly and downwardly from the planar mounting face to the central keel and follows a contour defining a sine wave pattern.

Boat hull
A boat hull, comprising a plurality of chines extending downwardly from a bow of the hull towards a stern of the hull, each chine in transverse cross section being substantially straight and substantially horizontal and arranged so that a centerline of each chine lies in a plane which is parallel to a central plane of an adjacent chine, wherein collectively the chines in a lower forward portion of the hull are arranged generally V shaped in cross section and wherein an aft portion of a base of the hull is generally flat and each chine terminates at the flat aft portion.
MARINE VESSEL HULL HAVING PROFILED PROPULSOR POD MOUNTING SURFACE

WATERCRAFT AND GUIDE
A watercraft includes a vessel body, a marine propulsion device and a guide. The marine propulsion device is attached to the vessel body and includes a water stream generator that propels the vessel body. The guide is provided on the vessel body and extends astern of the vessel body and toward a center of the vessel body in a width direction of the vessel body from a position located sideward of the water stream generator. The guide inwardly directs water flowing on one lateral side of the vessel body such that confluent timing of the water flowing on the one lateral side of the vessel body and water flowing on the other lateral side of the vessel body is caused to occur earlier than when the guide is not provided on the vessel body.
