Question 2463 Deck General

The correct answer is D. The reasoning is as follows: When loading in Albany, NY (a northern, temperate port) for a voyage to a port governed by the tropical load line mark, the hydrometer reading of 1.000 indicates that the water density is lower than the tropical seawater density. This means the vessel will be less submerged in the tropical port, requiring adjustments to the load line to ensure the vessel's stability and safety. Therefore, option D, which states that the tropical load line will be used, is the correct answer. The other options are incorrect because they do not properly account for the difference in seawater density between the loading and destination ports, which is a critical factor in determining the appropriate load line to use.
