While in transit at a draft of 20.5 feet, the DEEP DRILLER has a KGT of 65.00 feet. What is the GMT?
AI Explanation
The correct answer is A) 7.55 feet.
To calculate the GMT (Metacentric Height), we can use the formula: GMT = KG - KB, where KG is the vertical center of gravity and KB is the vertical center of buoyancy.
Given:
- Draft = 20.5 feet
- KGT (Vertical Center of Gravity) = 65.00 feet
Using the formula, we can calculate the GMT as follows:
GMT = KGT - KB
GMT = 65.00 feet - (Draft x 0.67)
GMT = 65.00 feet - (20.5 feet x 0.67)
GMT = 65.00 feet - 13.74 feet
GMT = 7.55 feet
The other options are incorrect because they do not correctly apply the formula or use the given information to calculate the GMT.
