A bit tricky... ha ha ha... with radar, GPS and a spotlight???? Ha Ha Ha Ha
I've done entries in to uncharted harbours at night ... drunk ... without
incident... and considered it child's play!

If you sail you vessel "drunk" then you can make no claim to being a good
sailor. Doesn't matter if you sail a mile away or 3000. There's nothing cool or
manly about a drunken fool at the wheel of a boat.
Sorry. Good sailors handle their vessels responsibly.
