LGRIG® Semi-Pelagic Trawl doors Sea Swallow

LGRIG® Semi-Pelagic Trawl doors Sea Swallow, also known as Trawldoor.

LGRIG® trawl doors are essential devices in commercial fishing, designed to control the movement and shape of fishing nets as they are towed through the water.

The size and shape of a trawl door depend on the fishing vessel's specifications and the target species, with some models featuring advanced additions like weight sensors or adjustable wings to enhance performance.

As fishing technology evolves, so do trawl doors—heavy wooden doors that once dominated European fleets have largely been replaced by steel doors, which now lead the market.

Today, the hydrodynamic design of trawl doors rivals the aerodynamic sophistication found in the automotive and aerospace industries.

Skippers develop personal preferences for trawl doors based on their experience, fishing grounds, and target catch.

Whether used in combination with a Trawling Bobbin or other ground gear, LGRIG® trawl doors deliver reliable performance and precise net control for the most demanding commercial fishing operations.
