The Tornado trawl door is different and innovative. This pelagic trawl door’s design incorporates five foils and the revolutionary patented Flow Booster. Developed to increase water flow through the foils, the Flow Booster has proven to generate extremely high lift, demonstrating some of the most impressive figures for any trawl door on the market. It’s a fact that Vónin’s customers have been able to reduce their trawl door size by an average of 25% when switching to Tornado trawl doors, providing a significantly lower drag.

Flexible, efficient and stable pelagic trawl doors
Flexibility is also one of the Tornado design’s key points. The angle of attack (AoA) can range from as low as 21 degrees, all the way up to 48 degrees and therefore the same set of doors can be used for a variety of trawl sizes and across a range of fisheries.
Tornado pelagic trawl doors work well up in the surface as well as performing close to the sea bed. Also on shallow waters, they have proven to be very efficient and stable. These doors have also been shown to work across the range of towing speeds, from 1.5 knots and up to 5 knots, and have been used successfully with both parallel and V-rig configurations, depending on the skipper’s preference.
These trawl doors are exceptionally stable. Even when making tight turns, the Tornado doors maintain their spread and keep the trawl open.
