I have a DeckHand 40 anchor winch and wouldn't be without it. I don't know how much current you're talking about,but I have never had a problem with my winch having plenty of power for the waters I fish in. I fish the Mississippi River in Pool 19 North of Keokuk,Iowa. If I can help you in any other way don't hesitate to ask,either on this thread or PM me if you want to. I'm sorry,I just noticed you were talking about the AnchorMate 40,which I know nothing about. Mine is made by MinnKota.
