I think that Hans has been in touch with Singapore to see about subsidies, but I haven't heard the outcome.
You're right about our near-continent colleagues as well - I would guess that they're looking at a couple of hundred pounds on the ferry? They could defray their costs I suppose by bringing a two-up or even three-up trailer - (one boat complete and two dismantled boats on top). Hell, if they can find a suitable trailer, they could probably bring 4 dismantled boats behind the one vehicle. But whichever way you look at it, it's going to be difficult to get 10 boats to ship from the UK.
What about you US guys? Anything happening on your side of the Pond?
