Lazy Jacks
Lazy Jacks contain mainsails while reefing and dousing. They work extremely well with full-battened mains, but are also used with conventional sails.
Single Line Reefing
Single Line Reefing shortens the mainsail in three easy steps: ease the halyard to a predetermined mark, tension the reefing line, and retrim the sail. Sails with reef points do not need modifying.
