A dampening platform includes a base and a first pedal assembly coupled to a first side of the base. The first pedal assembly includes a first pedal pivotably rotatable about a first pivot point at a first end of the first pedal. A first dampener is operatively coupled to the first pedal. The first dampener is configured such that the dampener is at less than full compression under a load of about 200 lbs. The first pedal assembly is slideably coupled to the base. A position of the first pedal assembly is laterally adjustable with respect to the base.

A suspension system for a marine vessel, the marine vessel including a body portion at least partially supported relative to at least a left hull and a right hull by the suspension system, the left and right hulls being moveable relative to each other and the body, the suspension system including resilient supports between the body portion and the left and right hulls. The suspension system providing at least a roll stiffness being arranged to provide a roll moment distribution (RMD) of the suspension system wherein roll forces effectively act at a position disposed within a longitudinal distance along the marine vessel from a steady state position of the resultant pressure forces acting on the left and right hulls when the marine vessel is operating in a planing or semi-planing mode. The longitudinal distance can be 20% or less of a waterline length of one of the at least a left and a right hull at design load in displacement mode.

Shock and vibration mitigation baseplates and related manufacturing methods. A shock and vibration mitigation baseplate includes a mounting frame configured for placement between a console operator chair and a rigid floor surface, and one or more viscoelastic polymer shock absorption and vibration dampening pads. The mounting frame houses the one or more viscoelastic polymer shock absorption and vibration dampening pads therein.

A boat includes: a hull; a float that supports the hull; a suspension that is disposed between the hull and the float and absorbs a vibration transmitted from the float to the hull; and a conversion mechanism that converts an energy generated in accordance with a relative movement of the hull and the float in a vertical direction, wherein the conversion mechanism is arranged so as to sandwich a center of gravity of the hull in a forward-rearward direction.

A watercraft mounting system that embodies a moving mounting platform and a protective hull cavity which provides protection, prevents damage and improves storage of data collection systems.

A fin stabilizer is provided for roll stabilization of a watercraft. The fin stabilizer includes a drive unit connected in a vibration-damping manner to a ship's structure. Specifically, a vibration damping element is provided between the drive unit and the hull of the watercraft wall such that a mounting portion of the drive unit is spaced from an attachment portion of the hull wall.

The electric hydrofoil watercraft according to the invention has a thermally insulated mast, thermal insulation and vibration isolation are provided between the mast and the above-water platform by placing an insulating element between them. This increases the life of the hydrofoil and improves user experience.

A noise reduction device for watercrafts that is positioned on a deck of the watercraft and faces an outboard motor of the watercraft. The noise reduction device includes a mount that may be affixed to the deck of the watercraft with a fastener. The mount includes a channel for receiving a panel. The channel may be angled toward the outboard motor so that the panel is angled toward the outboard motor when positioned within the channel. The panel may be formed from a material that reflects and/or absorbs sound that may be generated from the outboard motor, specifically a lower portion of the outboard motor including the exhaust port. The panel may also absorb and/or reflect sound generated from waves, wind, vibrations and the power head of the motor.
