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.
FEATURES
Fine-tunes are not just for tweaking, they are for ease of sail handling and power.
Fine-tunes enable you to pull the mainsheet on harder.
Fine-tunes make easing, bearing away, and dumping the main less dramatic.
Always pull the fine-tune block-to-block when sailing downwind.
