TYPE 4 is a development of our very known TYPE 2. This trawl door is a cambered V door but with two foils instead of one. The two foils improve the spreading power while at the same time it is lowering the resistance of the trawldoor, when towing through the water. This will result in less fuel consumption. And a more economical fishery.
