Hi Nial,
You've prompted my first post in ages......The opportunity is in repatriating good Brit SxSs to their original homes! The US$ rate would make that profitable, even with VAT and Customs rates. There already is quite a trade here in importing second-hand powerboats from the US.
Ammo – cannot be carried on the Ireland / UK car ferries, shipping line rule, I had some confiscated last year when going to Wales to shoot. Carrying guns on the same ferry is a hassle, requires usual permits, inspections, etc., but it was done by a very pleasant lady PC in Holyhead!
I have a good contact in the shipping business here if you need it.
Regards,
Bob.
PS splurged earlier this year on a nice pair of Pedro Arizzabalagas, 1957, 12g assisted openers.
