This is the mainsail handling system that is ready to use at all times. The unit is attached to the boom and is out of the way of all other sail operations. Made of UV-A and UV-B resistant marine materials means it will not be destroyed by the sun’s rays. The job of reefing or dousing the mainsail becomes a one person operation. Combined with the Tides Track and Slide System®, the sail will rest on the boom for a perfectly flaked sail.
