I think the critical factor is the duration of the stay - a lot of these exemptions to local law which apply to foreign vessels relate to what is described in international law as "Innocent Passage". You can claim exemption from local laws if you are passing through, possibly including stopping briefly in port, but if you stay for any length of time, then you have to accept the local laws.
"Innocent passage" does not include any stop in a harbour, except under duress. To be on innocent passage, your journey must start and end outside the territorial waters of the country concerned. Further, it doesn't include "internal waters", which in general means all waters inside the baseline - that is, the line joining prominent headlands and islands from which territorial waters are measured. For the UK, that inclides an awful lot of water, including most of the usual cruising grounds! There is a different general principle, though, where basically a country accepts that as long as a vessel follows the rules of its flag state, it will not be pursued for local rules. Comity, or something like that? I forget the exact name. But in general, that's a courtesy, NOT a rule, and there are plenty of exceptions.That's my understanding too. But I don't know where the boundary between innocently visiting the the EU and 'temporary importation' is.
