The history of Bison Trawl doors
Although Bison trawl doors were designed solely by John Ashworth from an original concept, their development was co-operation on an International scale.

(continued) The first Skipper John went to sea with was Colin Newby from Bridlington Yorkshire, on the M/V Karianda, but it was Skipper Bill Messruther from Scarborough, just up the coast, that persuaded and encouraged John to design and manufacture trawl doors, and over several years carried out the testing on his trawler “Success”. Further trials and assistance came from Ireland, especially Greencastle, Co. Donegal, Ritchie Duthie from Scotland, David Tait, in Nova Scotia, Canada, Bob Taber from Rhode Island USA, Pedro Garitoander from Spain, Asiaco from Reykjavik, Iceland, and later Bjorn Hansen, Norway, South Africa, New Zealand and Australia. All have helped develop the Bison door, of which John has visited and worked on their local fleets forever gaining experience, along with other counties in the world. This knowledge and experience covers fishing in very shallow to deep water. Using long sweeps or attaching the doors to the wing end. Single, double, or treble rigs. Different ground conditions and tidal areas. |
