The rotary of the COASTAL DRILLER is located 36 feet aft of the transom and 6 feet to starboard of the centerline. The hook load is 300 kips. Considering the changes to lightweight shown in the Operating Manual, the maximum amount of setback is __________.

Correct Answer: Option D — 224 kips

Determining maximum setback load involves applying the operational loading limits and moment calculations specified in the vessel's approved stability manual. By accounting for the specified hook load and structural position relative to the centerline and transom, the resulting allowable setback capacity calculates to 224 kips.
