A semisubmersible, 200 feet in length between draft marks with the LCF 10 feet aft of amidships, records the following drafts: Port Forward 74'-09"; Port Aft 78'-09"; Starboard Forward 69'-09"; and Starboard Aft 73'-09". What is the list?

Correct Answer: Option C — -5.0 feet

Vessel list is calculated by averaging port and starboard drafts forward and aft to determine true draft at the centerline, then dividing the transverse draft difference by the hull beam ratio. For this semisubmersible, the resulting transverse inclination computes to -5.0 feet starboard list.
