Question 1843Navigation General70% to pass

You are underway in a vessel with a draft of 6.0 feet. You are in an area where the charted depth of the water is 4 fathoms. You would expect the depth of water beneath your keel to be approximately _______________.

AI Explanation
The correct answer is A) 18 feet. In this scenario, the vessel has a draft of 6.0 feet, and the charted depth of the water is 4 fathoms. One fathom is equal to 6 feet, so 4 fathoms is equivalent to 24 feet. Since the vessel's draft is 6.0 feet, the depth of water beneath the keel would be approximately 24 feet - 6.0 feet = 18 feet. The other options are incorrect because: B) 30 feet is too deep for the given information. C) 24 feet is the total depth of the water, not the depth beneath the keel. D) 12 feet is too shallow for the given information.
