## CPC

- B63B 39/061: {by using trimflaps, i.e. flaps mounted on the rear of a boat, e.g. speed boat}
- B63B: SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING (arrangements of vessel ventilation, heating, cooling, or air-conditioning B63J2/00; floating substructures as supports of dredgers or soil-shifting machines E02F9/06)

## Abstract

A trim tab assembly including a hinge assembly and a trim tab. The trim tab includes a wedge-shaped body with a curved surface and a side. The curved surface, while in a deployed state, adjusts pitch, roll or yaw motion of a marine vessel. The curved surface is pivoted about a portion of the hinge assembly when transitioned between retracted and deployed states. A first portion of the curved surface extends below the marine vessel while in the deployed state and deflects oncoming water when a portion of the curved surface is extended below the marine vessel. A second portion of the curved surface is not below the marine vessel while in the deployed state. The hinge assembly is configured to attach to a support structure of the marine vessel rearward of the curved surface. The side extends between the curved surface and the hinge assembly.

## Claims

### Claim 1

A trim tab assembly comprising:
a hinge assembly; and
a trim tab comprising a wedge-shaped body, wherein the wedge-shaped body comprises
a curved surface that, while in a deployed state, adjusts pitch, roll or yaw motion of a marine vessel, wherein
the curved surface is pivoted about a portion of the hinge assembly when transitioned between a retracted state and the deployed state,
a first portion of the curved surface (i) extends below the marine vessel while in the deployed state, and (ii) deflects oncoming water when at least a portion of the curved surface is extended below the marine vessel,
a second portion of the curved surface is not below the marine vessel while in the deployed state, and
the hinge assembly is configured to attach to a support structure of the marine vessel rearward of the curved surface, and
a side extending between the curved surface and the hinge assembly, wherein the curved surface and the side define at least a portion of the wedge-shaped body.
