Abstract
A trim tab assembly for a watercraft includes a enclosure. A support structure is positioned in the enclosure. At least one trim tab is disposed in the enclosure. The trim tab includes a generally planar top, bottom, side and front surfaces linked by a curved surface defining a wedge shaped body. An actuator is linked to the trim tab pivotally moving the trim tab relative to the enclosure.
Claims25
A trim tab comprising:
- a first end comprising a first member;
- and
- a second end positioned rearward of the first end, wherein the second end attaches to a marine vessel via an attachment device, and wherein the first end adjusts pitch, roll or yaw motion of the marine vessel,
- wherein
- the first member has a first surface,
- the first surface is forward facing,
- the first member is pivoted about a portion of the attachment device and extends below a second surface of the marine vessel while in a deployed state,
- the first surface of the first member is convex-shaped, such that the first surface curves outward in a direction away from the attachment device, and
- the first surface of the first member deflects oncoming water when the first member is extended below the second surface of the marine vessel.
6 more elements
A trim tab comprising:
- a first end comprising a member, wherein the member adjusts pitch, roll, or yaw motion of a marine vessel;
- and
- a second end that attaches to the marine vessel via an attachment device,
- wherein
- the first end rotates about a portion of the attachment device,
- the member having a first surface,
- the first surface is forward facing,
- the member extends below a second surface of the marine vessel when transitioning from a fully retracted state to a fully extended state,
- while in the fully retracted state, a bottom surface of the member is above or in alignment with the second surface of the marine vessel, and
- while in the fully extended state,
- the member extends partially below the second surface of the marine vessel,
- at least a portion of the member is not below the second surface of the marine vessel, and
- the member extends at least from a first point, adjacent the second surface of the marine vessel, to a second point below and rearward of the first point.
10 more elements
A system comprising:
- an attachment device that attaches to a marine vessel;
- and
- a first trim tab connected to and positioned at least partially forward of the attachment device, wherein
- the first trim tab rotates at least partially about a portion of the attachment device between a fully retracted state and a fully deployed state to adjust pitch, roll, or yaw motion of the marine vessel,
- the first trim tab has a first end and a second end,
- the first end is positioned forward of the second end,
- the first end comprises a first portion and a second portion, wherein the second portion extends forward of the first portion and away from the second end, and
- while in the fully deployed state, the first end extends at least from a first point, adjacent a bottom surface of the marine vessel, to a second point below the bottom surface of the marine vessel.
