Product Description

Harken gross-trim/fine-tune Mainsheet Systems are easy to install and use. These optimized systems decrease overall line clutter because they use less line than traditional gross-trim/fine-tune systems. For fast trimming, pull both tails of the mainsheet. To fine-tune or to trim using a higher purchase, pull a single tail.

Harken Two-Speed Mainsheet Systems come in three configurations for boats from 22 ft to 39 ft (6.5 m to 11.8 m), with mains as large as 350 ft2 (32.4 m2).
