Concurrently to the developement of the software, the numerical model used to simulate trawl gears has been validated by  sea trials.

Two measurement trials were conducted aboard the oceanographic vessel Thalassa, taking advantage of  acoustic surveys  implementing a pelagic trawl and a survey bottom trawl.

Validation trials were also achieved abord the coastal oceanographic ship Gwen Drez.

For each trial, distances (vertical and horizontal openings, door to door distance) and tensions in the rig were measured by  means of acoustic sensors and autonomous force cells.

Despite the fact that we cannot guaranty that DynamiT will always provide results as good  as those presented below, we believe that this software is the most suitable tool to provide detailed and reliable information relative to a trawl gear.
