I wouldn't benefit from docking poles. I'm guessing you'd have to be in the water fairly deep for these to work with rollercoaster trailers or for the poles to project out from the rear quite a way. As soon as I've got tension on the winch cable the RIB is lined up and ready to go. However it's getting to this stage that docking poles would be most useful, but they'd have to be sticking out behind the trailer by as much as 8' to be any use (to stop the rear end of the RIB being blown out of alignment by cross winds/current).
