Reefing techniques are methods used to reduce the area of a sail in response to strong winds, ensuring safer and more manageable sailing. This is typically done by folding or rolling part of the sail, which decreases its surface area and helps maintain control of the vessel. There are various reefing systems, such as the jiffy reefing system, which allows sailors to quickly and easily adjust the sail from the cockpit. Proper reefing is essential for maintaining balance and stability, especially on larger vessels like yachts or sailboats, where excessive sail area can lead to capsizing.
