As you say, we shall see. I think you have a good point re red diesel prices, but if demand falls too much then marinas may fail, which would be worse still.
Ironicaly it could go the other way due to red diesel, if nobody is using their boats as much, they will at least want somewhere nice and posh to park them. This is probably the case already as lots of boats seem to be used just as holiday homes. /forums/images/graemlins/frown.gif
