My limited understanding of rules is that they have to go coastal. Mind you, if hitting a wave can bring down the mast perhaps there's a rule change on the way!
I don't think they can have it on a lake. Right now it looks like they will be pedaling it around trying to find the highest bidder, I understand the Italians have shown a lot of interest. If they play their cards right they may get enough to pay for the next defence.
