A jack-up level at 12.5 feet draft transfers 100 kips of drill water from a tank with a TCG of -30 feet to a starboard tank with a TCG of 70 feet. The resulting starboard draft is 13 feet. The moment required to change list one inch (MCL1") is __________.

Correct Answer: Option B — 833 foot-kips

Moment required to change list one inch is calculated using the transferred weight, distance between tank centers, and resulting draft change. Applying the transverse hydrostatic formula with a transferred weight of 100 kips and a 100-foot moment arm yields 833 foot-kips.
