I have always struggled with my anchor and unless calm water the waves will continue to make me drift. And its a 40lb anchor, I think the problem is the type of anchor. It is more mushroom shaped so the base that touches the ground I a smooth surface, so unless it is super muddy where im fishing or I get it pinned in branches beneath me I continue to drift. Is it because I has nothing to catch being smooth at the bottom? I fish lake mac with my boat so there are big waves most the time, but last trip I was fishing in the group of boats and there were guys all around me pulling up much lighter anchor than me and they weren't moving at all while I was ???
