I don't think anyone can specifically address your situation except as a
poll of what happened to them, which has zero applicability as to what will happen in the future. Once you've overstayed, the official in question can shrug it off and wave at you as you depart the anchorage, or can reflect on his poor choices in love, his nagging hemorrhoids, and (this is the important part) his country's near-bankrupt status and can steal your
boat...sorry, "impound"...because his mandate is to make the most
money possible from rule-breakers.
This is directly related to his salary continuation, of course.
So I wouldn't overstay one minute in
Europe were I you. I wouldn't carry Cuban
rum in U.S. waters, even though it's
legal for Canadian boats to do so. It is better to assume all bureaucracies are corrupt, crazy and money-grubbing, and the only way to avoid getting reamed is to play scrupulously within their rules.
