Barton Marine Lightweight Lazy Jack Cascade System up to 10.5m (35ft)Allow mainsails to be dropped with ease, by retaining the sail between lines running from the mast (near the hounds) to the boom. These lines can be slackened whilst sailing to avoid restricting sail shape. Ideal for use with fully battened or conventional mainsails, these complete kits contain a white polyester rope with plastic housings over the blocks and fixing eyes attached. All fixings and comprehensive fitting instructions are also included.
