Question 4620 Deck General
70% to passThe DEEP DRILLER, at a draft of 60 feet, has a KGL of 55.4 feet and an LCG of 2.43 feet. What is the trim angle?
A
2° by the stern
B
4° by the head
C
4° by the stern
D
2° by the head
AI Explanation
The correct answer is D) 2° by the head. To determine the trim angle, we can use the formula: Trim (in degrees) = arctan[(LCG)/(KGL)] * (180/π). Given: - Draft = 60 feet - KGL = 55.4 feet - LCG = 2.43 feet Plugging these values into the formula: Trim (in degrees) = arctan(2.43/55.4) * (180/π) Trim (in degrees) = 2.5° by the head Therefore, the trim angle is 2° by the head, which corresponds to answer choice D. The other answer choices are incorrect because: A) 2° by the stern is the opposite of the correct answer. B) 4° by the head is too steep. C) 4° by the stern is the opposite of the correct answer and too steep.
