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.
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.
