ABSTRACT:
A towable Otter Board having upstream facing flap portions is disclosed for use in trawl fishing applications. The flap portions are used to divert fluid flow from the concave lower board surface to the upper convex board surface which serves to shift a vortex formed proximate the upper board surface further downstream to a position closer to the trailing edge of the board which provides considerable improvement over the prior art by decreasing drag and increasing lift. A single wing and bi-plane version of the board is disclosed.
