We've been sailing for a little over a year now. We've encountered many US flagged boats where there isn't a single US citizen owner, captain, or crew aboard. This has been the case where the owner is Turkish, Israeli, Emirati, and lots of middle-east countries.<p>The super yachts still prefer to use the Marshall Islands, Caymans, or Gibraltar as their flag of registration.<p>Our boat is US LLC registered since my wife, a foreign national, can't be a direct owner for a US registered vessel. Nor can I be registered owner in her country as a non-citizen. So a US LLC is a convenient neutral mechanism. It's split 51/49% with me having the controlling shares as required by law.
