I have seen some wench's in my time usually hanging around bars frequented by pirates and motor bikers. I'd be afraid of an electric one. If your talking about an electric winch, I'd make sure your bow stop on your trailer is up to the task as I would imagine that is where you would want to mount it. I have seen ones that double up the cable using a pulley which I think would be slower but more powerful. We have a R27 and we usually just drive the boat on to the trailer. I don't know if you have a bunk type trailer on a roller trailer but if you have bunks I would think adding to plastic type slicks to make the boat slide on a little easier. These winches usually get powered by the tow vehicle. I would consider a remote control for the winch as a cables snapping and flying around are going to hurt! 😱
