Trawl board for fishing boat

The utility model relates to a trawl board for a fishing boat, which is used for single-boat trawl fishing to expand fishing nets. The utility model comprises a trawl board body and an upper and a lower connecting boards which are welded with each other into integration, wherein the trawl board body forms a tile shape, a water dividing tank is arranged on the trawl board body, the front face of the trawl board body is provided with an upper and a lower net rope tying boards, and the middle part of the back face of the trawl board body is welded with boat cable tying boards which are divided into an upper and a lower 2-3 steps; the upper and the lower connecting boards and the trawl board body are inwards inclined towards the back face to form an angle, except for welding edges, other peripheries of the connecting boards form a circular-arc shape and form smooth transition with the arc line of the periphery of the trawl board body, wherein the upper connecting board is a hollow board and a balance weight is filled in the lower connecting board. The trawl board of the utility model can be floated by an effective angle due to the integral concave structure, the design of the circular arc of the periphery and the water dividing tank can reduce the resistance force of the trawl board which has the advantages of good equilibrium and stability and adjustable range of use; the utility model can be used for catching fish of bottom layers as well as fish of middle and upper layers, the fishing nets have adjustable expanding angles and the maximum expanding angles can reach more than 80m.
