The dock Roll-Aid is a new and clever product that  makes getting your canoe or kayak from the dock to the water (and back again) singlehandedly a snap! The foam-padded roller ensures protection for the boat's hull while remaining out of the way on your dock or bulkhead. It serves as a tie-off for your boat if needed. Check out the video (on right) and see how easy and convenient the Roll-Aid is. Easy installation; four screws hold it in place. It's well made and durable.
