Single Line Reefing
Single Line Reefing makes shortening your mainsail a quick, easy, three-step process: ease the halyard to a predetermined mark, tension the reefing line, and retrim the sail. Harken's system is based on Garry Hoyt's patented concept and includes everything you need to install the system except the line and a cleat or stopper. Sails with reef points do not need modification.
Lazy Jacks
Lazy Jacks contain mainsails during reefing and dousing. They work exceptionally well with full-battened mains, but are also used with conventional sails. Kits include pre-swaged, vinyl-coated stainless cable, ball bearing blocks, eyestraps, line, a cleat, fasteners, and pictorial instructions.
