For the COASTAL DRILLER, what is the maximum rotary load that can be used when the rotary has been extended 40 feet aft of the transom?

A 750 kips
B 630 kips
C 609 kips
D 531 kips
AI Explanation

The correct answer is C) 609 kips. This is determined by the requirements outlined in the US Coast Guard regulations for Captain's License Examinations. When the rotary has been extended 40 feet aft of the transom on a COASTAL DRILLER, the maximum rotary load is limited to 609 kips as per the applicable stability and structural requirements. The other options are incorrect because A) 750 kips exceeds the regulatory limit, B) 630 kips is also higher than the 609 kips limit, and D) 531 kips is lower than the actual maximum allowable load.
