Which sail setting indicates the sail is not luffing?

• A. Furl
• B. Full
• C. Sheeted
• D. Reefed

Answer: (B)

When a sail is not luffing, the wind is filling the sail along the leading edge, giving a smooth, rounded silhouette rather than fluttering wrinkles. That filled, supported shape is described as a full sail. So, choosing a full sail indicates the sail is trimmed to a level where the wind holds it full and steady. Furl means the sail is rolled up or secured and not set to catch wind. Reefed reduces the sail area, which can still luff if not trimmed properly. Sheeted refers to trimming the sail at the clew, but simply being sheeted in doesn’t by itself guarantee the luff isn’t luffing. The key idea is that a full sail is filled by the wind and won’t be luffing.
