A 10 feet 8 inches
B 10.7 feet
C 10.3 feet
D 10 feet 4 inches
AI Explanation

The correct answer is D) 10 feet 4 inches. To calculate the new draft, we can use the formula: New Draft = Original Draft - (Discharged Weight / Displacement per Inch). The COASTAL DRILLER has an original draft of 10.5 feet and discharges 216.43 kips (kips = 1,000 lbs) of weight. Assuming the vessel has a constant displacement, the new draft can be calculated by dividing the discharged weight by the displacement per inch, which is typically around 2.5 kips/inch for a vessel of this size. Plugging in the values, we get: New Draft = 10.5 feet - (216.43 kips / 2.5 kips/inch) = 10 feet 4 inches, which matches the correct answer choice D.
