A few threads on this subject already (so worth a search) - but IIRC, Atoll is right - need to be a US citizen to have a US flag (USCG Documented is their term) but you could get State Registration
. the downside to that is as not a national register that acceptability may well expire the further you travel from the US backyard - upside is that the boat won't be "foreign" (in the US)and therefore subject to the same rules as if you had arrived from UK on own keel
- but I think you can get a (1 year?) crusing permit
for your foreign reg boat easily enough. Your Visa status is of course different to the boat, no matter how it is registered.
One thing to bear in mind if you use a US reg is that they like their rules! - including on equipment
fitted onboard. As a foreign reg boat you are governed primarily by the requirements of own flag (and with SSR that basically zero!) - of course that does not mean you are exempt from following local US laws, especially on stuff like head
discharge (the US seems to be very keen on regulating how folks poop).
I would go for the UK SSR (Part 3) - cheap
and easy and boat don't need to visit the UK (nor pay VAT - that only happens if it arrives in the UK / EU). Will just need to delist from whatever US registry (USCG or State) the boat is on, not to get on the SSR (what they don't know they don't care about) but to ensure that no complications by having dual registration. Unlike the US registrations the UK SSR is not proof of ownership
- so make sure you get a Bill of Sale
Sales tax in the US sounds wildly complicated! - the rules seem to vary by State, I will let someone else tackle that one!
