Question 31 Deck General

The correct answer is B) Reduce the area of a sail. Reef points are used to reduce the area of a sail, typically the mainsail, when the wind conditions are too strong. By using reef points to gather and tie down excess sail material, the overall sail area is decreased, which helps to prevent overpowering the boat and making it more manageable in high winds. This is an important safety measure to prevent damage to the boat and its rigging. The other options are incorrect because reef points are not used to reduce draft (A), keep the sail taut in light airs (C), or increase the strength of the mast (D). These are not the primary functions of reef points on a sailing vessel.
