Question 2193 Deck Safety

The correct answer is A) deck edge immersion. The angle of maximum righting arm corresponds approximately to the angle of deck edge immersion. This is because the righting arm, which is the distance between the ship's center of gravity and the line of action of the buoyant force, reaches its maximum value at the angle of deck edge immersion. Beyond this angle, the righting arm starts to decrease as the ship becomes increasingly unstable. The other answer choices are incorrect because they do not directly relate to the angle of maximum righting arm. B) loll refers to a stable heeled position, C) the load line is the waterline indicating the maximum safe draft, and D) downflooding refers to the angle at which water starts entering the ship's interior through openings.
