The correct way is to have a marine batter charger that passes thru a galvanic isolater then through a marine receptacle and heavy 50amp marine cord to a dock receptacle.
Doing it wrong can cause very rapid erosion of underwater metals. I have seen the drain plug erode to the point of near failure in a VERY short period of time.
Another problem it you may not make any dock friends. The guy next to you could have problems due to your set up if he is plugged in as well.
I don't like leaving pumps on all night but you can, they will burn up eventually esp cheap jabsco pumps but just get a new one per Mikes suggestion. I replace every pump on my boat almost every 2or3 years it seems.

Thanks to everyone for the advice.
