Most of the time, people kneejerk "Impossible" when they hear Sealion. Then they explain what was wrong with the OTL plan. That's all well and good, but what if the Nazis hadn't been so bloody stupid? People tend to start off, and then say, "But of course that wouldn't be OTL Sealion, so we should forget it entirely". Why?
Your challenge, then, should you choose to accept it, is to create a plausible invasion of Great Britain by the Third Reich, with a POD no earlier than 1933.
