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?

A -1.0 foot

B -2.5 feet

C -5.0 feet

D -10.0 feet

AI Explanation

The correct answer is C) -5.0 feet. To calculate the list, we need to use the formula: List = (Port Draft - Starboard Draft) / 2. From the given drafts, we can calculate the port draft as (74'-09" + 78'-09") / 2 = 76'-09", and the starboard draft as (69'-09" + 73'-09") / 2 = 71'-09". Plugging these values into the formula, we get: List = (76'-09" - 71'-09") / 2 = -5.0 feet. The other options are incorrect because they do not match the calculated value of -5.0 feet.
