Go out on the internet and look at a contraption called the 'Drop n Stay'. It attaches to an anchor line and takes a lot of pull out of the line when the boat is pushed by waves. I may move 1-2 feet when a waves pushes my boat but the 'Drop n Stay' will recoil and minimize/eliminate/prevent the anchor from popping off the bottom. It's a $30.00 piece but watch the video and make your own call. It works for me and only drop 100' of line when fishing.
