I was just wondering if any has ever installed (or thought of trying) on of the worm gear winches from Dutton-Lainson? I like the idea of easily and quickly being able to use a cordless drill to load/unload the boat, but what concerns me is that there is no locking pawl. I know the worm gear shouldn't backdrive, but with the vibration going down the road I think I'd want to put some kind of lock on it? Figured I'd ask here first though :)
