Question 1946 Deck Safety

The correct answer is A) amidships. The amidships point is the point that is exactly halfway between the forward and aft perpendiculars of a vessel. This point is used as a reference for vessel construction and measurement, as it represents the midpoint of the vessel's length. The amidships point is a key reference point for determining the vessel's dimensions, stability, and other important characteristics. The other answer choices are incorrect because they do not accurately describe the specific point that is halfway between the forward and aft perpendiculars. "Mid-body" and "half length" are more general terms that do not necessarily refer to the amidships point, while "center line" refers to a different reference line along the vessel's longitudinal axis.
