While underway in a field move with the lower hulls awash, a semisubmersible has a maximum allowable KG of 63.69 feet; KMT is 65.12 and KML is 64.92. The KGT is 56.13 and KGL is 55.89. What is the margin on the maximum allowable KG?
AI Explanation
The correct answer is B) 7.56 feet.
The margin on the maximum allowable KG is the difference between the maximum allowable KG (63.69 feet) and the actual KG (56.13 feet). To calculate this, we simply need to subtract the actual KG from the maximum allowable KG: 63.69 feet - 56.13 feet = 7.56 feet.
The other options are incorrect because they do not accurately represent the difference between the maximum allowable KG and the actual KG. Option A (1.43 feet) is too small, Option C (7.80 feet) is slightly too large, and Option D (8.99 feet) is significantly too large.
