Brendan's answer makes a lot of sense - speak to a good lawyer.

In general terms, under British law, no-one can pass-on good title unless they own good title. Presumably, the Asian country's government have legislation in force that enables them to become the boat's legal owner. If that is the case, I would expect that they could legally sell it and the new owner could legally own it.

Having said that, please re-read the first line of this posting.
