In the mid to late 80's I fished on this boat for a few years running out of Bridlington - charter fishing for cod & ling etc - skipper Mick Tranmere - the enclosed rear passenger area had been removed to leave a large open rear deck.
During this time Mick had the two Detriot diesels replaced with Ford diesels to save fuel is my recollection - many happy times if v cold in winter!
