Question 1902 Deck Safety

The correct answer is B) amidships. The keel scantlings, which refer to the thickness and dimensions of the keel, should be the greatest amidships. This is because the amidships section of the vessel experiences the highest bending stresses and loads during the ship's operation, and the keel needs to be strongest in this area to provide structural integrity. The other options are incorrect because the keel scantlings should not be the greatest at one-third the distance from the bow (A), one-third the distance from the stern (C), or at each frame (D). These locations do not experience the same level of stress and loading as the amidships section.
