70% to pass

If you reef a marconi mainsail, the sail area _______________.

A becomes less
B does not change
C moves aft
D becomes larger
AI Explanation

The correct answer is A) becomes less. When you reef a Marconi mainsail, you reduce the sail area by shortening the length of the sail. This is done by rolling up or tying down a portion of the sail, effectively decreasing the overall surface area that is exposed to the wind. Reefing the sail allows the boat to maintain control and stability in stronger wind conditions without overpowering the vessel. The other options are incorrect because B) the sail area does not remain unchanged, C) the sail does not move aft, and D) the sail area does not become larger when reefed.
