To reef the sail you roll the fabric up from the bottom and tie it in place at the reef points. What is the purpose of this?

To increase sail area

To repair the sail mid-race

To reduce the sail area and lessen the danger of capsizing the boat in very strong winds

In strong winds you reef to keep the boat controllable and safe by reducing the sail’s power. Rolling the bottom of the mainsail up and tying it at the reef points creates a smaller, flatter sail that catches less wind. That lowers the driving force on the sail, reducing heeling and helping you maintain balance, steering, and overall control in heavy weather. It’s about safety and manageability in strong winds, not increasing speed, repairing the sail, or changing its color.
