Sorry for the late responses.....work again.....I wish they'd give it a rest for a mo!
Steve the reason I'd go for diesel is that although petrol is widely available in the channel islands it's not alwasy the case along the coast of france. Plus the amount I use the RIB (knocking on roughly 5 days a week she's out and about) the benefit of cheaper diesel starts to make sense.
I realise the performance will suffer and I know what you mean that a pair of 200-250's would be superb, but then double the engine and it's half the coast again almost. Still undecided though and the big thing will be the overall cost of purchase.
JIY - No not at all. I'm a toy person......I get a toy, love it and then want a bigger and better one!!!
Also since I got the rib several divers I know have come back out of diving retirement and so it's getting a little cramped. The original plan for the rib was for 3 or 4 divers and then seating for the times we weren't diving, but there are now 7 or 8 starting to become more regular.
As for the boat being flightly.......not really, but then with hardly any fuel and all the kit removed she does get a little twitchy at 50knts in the rough. However most of the time with the kit on board she's as steady as a rock.
Also in a slightly better financial situation than I was.
