What does the outhaul primarily affect on the mainsail?

• A. The shape of the sail
• B. The depth of the draft
• C. The height of the sail
• D. The angle of attack

Answer: (B)

The outhaul primarily affects the depth of the draft in the mainsail. The outhaul is a line that adjusts the tension along the foot of the mainsail (the bottom edge). By pulling the outhaul tighter, you flatten the sail, which reduces the draft and simultaneously alters the sail's shape. This is particularly significant because the draft is the point at which the sail is most "bulged" out, directly impacting the sail's ability to generate lift. A well-adjusted outhaul enables sailors to shape the sail according to wind conditions. For instance, in heavy winds, a flatter sail with a reduced draft will minimize heeling and improve control. Conversely, in lighter winds, a fuller sail with more draft can catch and hold more wind. Understanding this mechanism is crucial for effective sail trim and performance on the water. While the outhaul does have secondary effects on the sail's overall shape, the primary purpose and effect of adjusting the outhaul is indeed on the depth of the draft.
