The DEEP DRILLER, in transit at a seawater draft of 19 feet, enters a fresh water port. What is the new draft?
AI Explanation
The correct answer is B) 19.40 feet.
When a vessel enters fresh water from seawater, its draft increases due to the lower density of fresh water compared to seawater. This phenomenon is known as the "fresh water effect." The formula to calculate the new draft in fresh water is: Fresh water draft = Seawater draft x (1.025), where 1.025 is the typical density ratio between seawater and fresh water.
Given the seawater draft of 19 feet, the new draft in fresh water would be 19 feet x 1.025 = 19.475 feet, which rounds to 19.40 feet. The other options are incorrect because they do not accurately reflect the fresh water effect on the vessel's draft.
