1. Can I register it there under my name?
2. If so, will VAT remain valid for Med cruising if sailed there within the 3 years?
I can only tell for French regulations
. If the taxes
are already paid, this is lost money
for a non-resident except if he keeps the boat longer than the temporary import rule
: 18 months in the French Antilles, 18 months in the EU, or 36 months in French Polynesia
(this is called temporary import
, free of taxes). I don't know for other countries.
You have to know that EU tax rules don't apply to many European overseas territories : Channel islands, French overseas departments, Canary islands, mount Athos, Ceuta, Mellila, Helgoland island, Büsigen Territory, islands Aland, Livigno, Campione d’Italia, Italian waters of Lugano Lake !! But... the Azores
belong to EU tax zone and have the same VAT and import rules !
Your question  : the 3 year countdown you are talking about seems (IMHO) to be related to EU residents who would re-import a boat after a previous export, but many different cases can still occur and you'd better forget this.
Your second question 
: you can only register locally if you are resident or at least half of the owners are residents, otherwise no. To my knowledge, this is common to all European countries and territories.
Your third question, named 
: as non-resident, as far as you don't import the boat in whatever European country or territory, you don't care about VAT. But don't forget all Mediterranean
countries are not EU : Turkey
, Middle East and Northern Africa
countries have all their own rules.
Hope this helps !
