Roll mitigation involves which of the following actions?

• A. Turn broadside to the seas
• B. Increase speed
• C. Shifting ballast to starboard
• D. Stow loose articles and keep the vessel not broadside to the seas

Answer: (D)

Roll mitigation is about reducing the vessel’s side-to-side motion by limiting things that can move and by minimizing how waves hit the hull. Securing loose articles prevents items from shifting during a roll, which would add to the rolling motion and could cause damage or injury. Keeping the vessel oriented so it is not broadside to the seas reduces the wave energy that excites rolling—the waves strike the bow or stern rather than the sides, leading to less roll. Turning broadside to the seas tends to increase rolling because the hull presents its maximum beam to the waves. Increasing speed or shifting ballast to one side can alter motion or trim, but they don’t reliably reduce roll and can introduce other stability problems.
