Yacht registered under a permanent merchant statute;
Yacht permanently crewed according to the safe manning emined by the Flag state;
Yacht has to report year per year to the VAT authorities the prorate basis in voyages she has sailed internationally and outside the 12 miles zone;
The VAT- exemption on the operation costs of yacht has to be qualified as precarious as the authorities got the right to re-qualify the statute of the previous civil year as the one of the running year.
So this VAT- regime should only be applied to yachts (1) over 24m waterline, (2) permanently crewed and (3) foreseen for at least the first two years to be operated in international voyages.
