70% to passThe DEEP DRILLER departs a fresh water port at a draft of 19.5 feet. What will be the draft in sea water?
A
18.7 feet
B
19.1 feet
C
19.4 feet
D
19.8 feet
AI Explanation
The correct answer is B) 19.1 feet. When a vessel transitions from fresh water to sea water, its draft will increase due to the higher density of sea water compared to fresh water. The formula to calculate the change in draft is: Fresh water draft x (Fresh water density / Sea water density) = Sea water draft. Assuming standard fresh water density of 1.000 g/cm^3 and sea water density of 1.025 g/cm^3, the calculation for the DEEP DRILLER's draft change is: 19.5 feet x (1.000 / 1.025) = 19.1 feet. The other answer choices do not correctly apply this density-based draft calculation.
