Question 1858 Deck Safety

The correct answer is C) amidships. In the illustration D041DG, symbol 3 represents the amidships reference point, which is the vertical line that passes through the midpoint of the vessel's length. This is a standard reference point used in vessel measurements and stability calculations. The other answer choices are incorrect because: A) Displacement is the total weight of the vessel and its contents, not a specific reference point. B) The forward perpendicular is the vertical line at the forward end of the vessel, not the midpoint. D) The baseline is the horizontal reference line at the bottom of the vessel, not a vertical reference point.
