Which general boat design feature is listed as influencing stability?

• A. Shape of hull
• B. Color of hull
• C. Engine type
• D. Propeller size

Answer: (A)

Stability is governed by how buoyancy shifts as the boat tilts. The hull shape determines how the center of buoyancy moves when the vessel heels, which creates the righting moment that resists capsizing. A hull with a wider beam (broader shape) generally produces a stronger righting moment at small tilts, improving initial stability. That’s why the hull shape is the general design feature that most influences stability. The hull color has no effect on buoyancy or balance. Engine type and propeller size affect propulsion and weight distribution, but they don’t define the fundamental stability provided by the hull form.
