Hi there! Today, let's see how to furl and unfurl a mainsail with an in-mast furling system, in just three simple steps.

Adjusting the Boom Height

Start by adjusting the boom height. Lock the topping lift and the vang to set the boom in the right position.

The leech and the foot of the sail should have equal tension. This helps the sail furl smoothly without creases inside the mast.

Tip: Mark your lines near the cleats to easily find the right setup before each maneuver.

Unfurling the Mainsail

Wrap the outhaul around the winch a few turns, then secure it in the self-tailer.

Open the furling line’s cleat and keep light tension on it as the sail comes out.

Unfurl slowly and guide the sail out by hand.

Tip:Always keep an eye on the sail to prevent line jams and chafing against the rigging.

Furling the Mainsail

Wrap the furling line on the winch with a few turns and secure it.

Open the three cleats: both furling line ends and the outhaul.

Pull gently on the furling line while maintaining light tension on the outhaul.

This ensures the sail furls tightly into the mast, without wrinkles.

Tip: The sail should stay stable—no flapping. Use both lines to control the furling and avoid jams inside the mast slot.

Conclusion

Always furl the sail facing the wind, and do it gently.
