I want to add a stern anchor to my Hunter 25. The only purpose which I want to add it is to give me some security when I am heading in or out of the marina under power and my motor dies. I has happened a few times and when I am alone, I don't have time to go forward and deploy my anchor. Also, I don't like to leave the helm. I was thinking of adding a "quick deploy" anchor attached to the stern or reasonably close to the helm. Has anybody done this on a 25 or 26 Hunter or similar sized boat? What type of anchor? How big should I go? I don't know if a mushroom anchor would be better as it would be in the cockpit area and less sharp edges, etc compared to a Danforth.
