Thanks for the response,, interesting that some Marinas don’t have Petrol hope that’s not becoming a trend as I’ve heard LPG is also becoming scares having failed to meet peoples expectation. I reckon your right about the Diesel being more robust in a marine environment and of course the increased cruising range must be considered although in my case £8000 extra for the same vessel just because it has a Diesel Engine buys an awful lot of petrol.
