The Effectus trawldoors

The main object in design and developing process of Effectus trawldoors was to obtain as good spreading force know by best doors makers on the market but more importantly, to achieve less resistance. With computer simulations, several trips to Flume Tank testing and modification after actual fishing trial backed up with experienced friends and skippers, Effectus trawldoors high spreading force and reduced spreading force has been confirmed.


Here is a video from a recent testing wich had a promising result for us.
