Question 1518Navigation General

The correct answer is C) 30.0 feet. Explanation: 1. 1 fathom = 6 feet, so 6 fathoms = 36 feet. Since the chart indicates the depth is 6 fathoms, and your draft is 6.0 feet, the depth of the water under your keel is 36 feet - 6 feet = 30.0 feet. 2. This calculation is based on the standard conversion between fathoms and feet, and the understanding that the charted depth and the actual depth are the same. 3. The other options are incorrect because: A) 6.0 feet is the draft, not the depth of water under the keel. B) 26.5 feet is not the correct calculation. D) 56.5 feet is not the correct calculation.
