angle of attack of trawl board
shoe plate of trawl board
The invention relates to an otter board (20) which may be used for generating a spreading force in connection with trawl fishing.
The preferred embodiment is a V-shaped trawl door made up of two sections (28, 29) of door.
A trawl door having enhanced and rather high efficiency, lightness of weight in water and ease of manufacture.
The trawl door (10) in another aspect is characterized by having an aspect ratio of at least two to one (2.0 : 1.0).
An improved trawl door (10) is adapted for being towed through water both at shallower and at larger angles of attack.
The trawl door (10) includes at least one main deflector (24, 25) having a profile (46) formed by an inner surface (48) and an outer surface (47).
Michel Dagorn of Morgère said: “It was great to meet fishermen who are already using the Exocet door and are reporting excellent fishing results.
