Question 1843Navigation General

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.
