Question 4636 Deck General

The correct answer is C) 19.6 feet. The reason is that when a vessel transitions from fresh water to sea water, its draft will increase due to the difference in water density. The formula to calculate the change in draft is: Fresh water draft x (1.000 - 1.025) = Change in draft. In this case, the fresh water draft is 20 feet, and the change in draft is 0.6 feet, resulting in a sea water draft of 20 feet + 0.6 feet = 19.6 feet. The other options are incorrect because A) 19.0 feet is too low, B) 19.3 feet is too low, and D) 20.4 feet is too high compared to the calculated value of 19.6 feet.
