Question 4866Deck General70% to pass
The DEEP DRILLER, at a draft of 60 feet, has VM of 942,120 ft-tons, and FSML of 36,235 ft-tons. What is the KGL?
AI Explanation
The correct answer is C) 54.0 feet.
To calculate the KGL (Keel-to-Gunwale Height), we can use the formula: KGL = (VM / FSML)^0.5
Given:
- Draft = 60 feet
- VM (Vertical Moment) = 942,120 ft-tons
- FSML (Freeboard Strength Moment) = 36,235 ft-tons
Plugging these values into the formula:
KGL = (942,120 / 36,235)^0.5
KGL = 54.0 feet
The other options are incorrect because they do not match the calculated value of 54.0 feet. This calculation is based on the standard formula used to determine the Keel-to-Gunwale Height for a vessel, which is a key parameter in Coast Guard Captain's License Examinations.
