摘要:
The present invention relates to trawl doors used in trawl fishing, including shallow water trawl fishing applications, deep water trawl fishing applications, bottom trawl fishing applications as well as at pelagic trawl fishing applications. The invention also relates to seismic surveillance line spreading and spreading of other items towed in water. The present application provides a novel trawl door design with improved stability and efficiency. The inventors are able to demonstrate smaller angles of attack using the trawl door of the present invention, which is as little as 7.5 degrees.
