I have had a issue with storing my new 2.5 rib for a number of months....I have towed it in up to 20knts it could work as a sea anchor in big seas or on the deck or on the deck which is painful but the safest . today completed a hinge system on my transom so the tender hinges transom to transom and raises from the bow until vertical. As I have a narrow strern a davit system is not practical for a Dunc. What do you guys do?
