Question 4692 Deck General
70% to passThe DEEP DRILLER departs a fresh water port at a draft of 20.5 feet. What will be the draft in sea water?
A
18.2 feet
B
19.4 feet
C
19.7 feet
D
22.8 feet
AI Explanation
The correct answer is C) 19.7 feet. When a vessel transitions from fresh water to sea water, its draft increases 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. Since the DEEP DRILLER's fresh water draft is 20.5 feet, the change in draft is 20.5 x (1.000 - 1.025) = 1.025 feet. Therefore, the vessel's draft in sea water will be 20.5 + 1.025 = 19.7 feet. The other options are incorrect because A) 18.2 feet is too low, B) 19.4 feet is too low, and D) 22.8 feet is too high compared to the correct calculation.
