Surf to Summit, Santa Barbara, California, USA have made the best idea for getting both kayaks off the floor and storing them on their sides against a wall.A space-saving, easy-access wall-mount hanger that works for both individual and Multi boat owners. Each set stores up to two kayaks/SUP's and two paddles.
The Double Wall Slings are able to carry 2 kayaks and 2 paddles.
We have used them for years to display different kayaks on the front wall at PaddlerZone.
It will handle white water kayaks, sea kayaks, fishing kayaks, SUP's and Canadian style canoes all with ease.
