As long as you control your Flagship, it is unsinkable by any means (edited above).
If the controller is different, no one can save it from Davy Jones locker.
This design will allow Flagships to only be lost in battle but they will be able to reclaimed either through Tidal Wave (or shipwreck expedition later), through battle and through Ships Market. Private Marina will be the only true obstacle to be kept away from your Flagship once stolen and probably there will be an exception to this so controllers will not be able to dock them to the Marina unless they are also the owners.
