Vónin Tornado

Pelagic trawl doors

Generating extreme lift

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.

Very happy with the Vónin Tornado. Not only am I getting much better trawl openings and improved towing efficiency. I also can turn more aggressive on fast moving fish marks while maintaining the full opening of the net.”

Allan Simpson, Christina S

Flexible, efficient and stable

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 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.

Fast and easy

A feature which the skippers also have expressed great satisfaction over is how easy and fast the Tornado doors are to shoot. As soon as the doors hit the water the Flow Booster kicks in and the doors start spreading, and submerge immediately as the wire is shot away.

Strength

We see the critical importance of the strength of the product, and for this reason the Tornado doors are constructed using high-quality steel, with fully welded seams on all joints and all welding procedures are certified.

WORK WITH PARALLEL AS WELL AS V-RIG

MAINTAIN THEIR LIFT WITH BOTH LOW AND HIGH TOWING SPEEDS

STABLE WHEN FISHING IN THE SURFACE

STABLE WHEN MAKING SHARP TURNS HOLDING THE OPENING
