All nets manufactured by SNG are custom-designed to the skipper’s particular requirements. Vessel horsepower, target species and mesh size requirements are all taken into account and married to our design team’s expertise in gear and materials.
 Key designs have been proven at sea by many top skippers worldwide; our trawl models also have been tested under simulated conditions in the flume tank. This has enabled Swan Net Gundry to produce the most successful range of gear ever.

3D Simulation Design

As we evolve in our Trawl Design Techniques our new 3D Simulation application has aided us in providing real life experience on the actual trawl.

Our Simulation Software allows us to input all the parameters of a trawl gear; bottom trawls with two panels or more, pelagic trawls, twin trawls or more. The software simulates the mechanical behaviour of the fishing gear, while  solving the momentum equations and taking into account the hydrodynamic forces applied to each part of the gear.

At the end of the simulation, which can last some minutes to several hours, depending on the complexity of the trawl gear, the results are available:

  • The geometry; any distance and co-ordinate (e.g. openings, door to door distance, depth)
  • The forces: tensions in the rig, in the strengthening ropes and towing force

Flume Tank Experience

Investing in innovation is fundamental to the growth of our business.

The flume tank is an exceptional way for us to trial our new trawl designs in the tank and watch how it reacts to the water.

We develop our designs in conjunction with this and we can make real time decisions on aspect of our gear.
