In 1939 was the fastest ship in the RN - and we had a massive navy then, saw her last year at Sandwich altho' flying the Red Duster now. When I was on Defiance in '52 we had 3 MTBs as tenders (not 102) and also 2 midget submarines - went aboard one of the MTBs but didn't get a trip. Got a feeling she has not the original engines - can you imagine the petrol bill?
