http://www.producttank.co.uk Save the sea bed prototype trawler doors. I researched how fishing nets and trawler doors damage the sea bed. So I tried to invent an innovative solution to raise the trawl doors off the sea floor to try and prevent or reduce them stirring up the sediment and then reintroducing plastic particles back into the food chain. I conducted several experiments in my garden pond by making models until I arrived at something that showed promise. To be put into production it would need a lot of work, but it is simple and would be easy to maintain and repair whilst at sea. The idea is a leg keeps the trawler doors away from the sea bed. The leg keeps in contact with the sea bed and moves a set of fins to adjust to the changing contours of the sea floor. As the sea bed rises, the fins are lifted up to lift the trawl doors higher in the water, so that the contact with the sea bed and damage done is kept to a minimum.
