Mainsail Reefing Systems

Mainsail reefing systems must operate effciently to reduce sail under adverse conditions and provide proper sail shape when reefed. These systems are a must for both racers and cruisers.

Typical Boat Length:
Small Boat: 22' - 28' (6.7 - 8.5 m)
Midrange: 29' - 34' (8.8 - 10.4 m)
Big Boat: 35' - 42' (10.7 - 12.8 m)

 

Single Line

The single line reefing kit is easy to install and use. To reef, simply ease the halyard to a predetermined mark and pull the single reef line taut. Ideal for boats from 22 ft to 27 ft (6.7 m to 8.2 m) with a maximum sail area of 150 ft2 (14 m2).

Dual Line

This dual-line system is common on boats 30 ft (9 m) and larger. Position blocks so line pulls down and out to keep the sail flat and prevent lateral loads on the luff rope or luff sliders.

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.
