Hi everyone,Im a very new member(just signed up)I am heading at last towards a late retirement later this year and my partner and I intend buying a liveaboard to cruise the English canals and also around Europe.I have been looking at the multitude of boats types available and after also looking through the forum think a wide beam is most suitable.I have seen many cruisers some twin engine,which brings up the question does a twin use twice the amount of fuel and if so is it best to stay with a single,
