A trim tab assembly includes a trim tab and a support structure. The trim tab includes first and second ends. The first end includes a member or a curved surface. The member or the curved surface, when in an extended state, adjusts motion of a marine vessel. The second end attaches to the marine vessel via an attachment device. The member or the curved surface is convex-shaped such that the member or the curved surface curves outward in a direction away from the attachment device. The support structure attaches to the marine vessel. The support structure includes a scraper plate. The scraper plate is adjacent the member or the curved surface. The member or the curved surface moves relative to the scraper plate while transitioning between a retracted state and the extended state.
