I have a British registered ex VAT boat that I am moving from UK to the Red Sea all be it very slowly. I have purchased ex vat this winter davits,RIB,hydrovane and six sails all ex vat which have been shipped to the boat within the EC. However I do have an address and am non resident within the EU as I have been working in the Middle East for some years. Many of the suppliers checked up with the UK VAT office and were told that what I was doing was OK. The boat is technically in transit. My advice would be to find a friend who has an address outside the EU.
