FS44 - 12.09 Dec 2009 Trawl door rigging

Summary

This fact sheet gives generalised pointers on the rigging configurations possible for demersal trawl doors and the effects various alterations to the rigs have on the performance of the trawl door. The fact sheet looks at the five main types of towing point arrangements used in otter board design and construction: towing chain, combination chain and bracket, horizontal hinge bracket, triangle fixed bracket and fixed bracket. Each has characteristics which make them suitable for a variety of fishing methods or seabed conditions.
