The DEEP DRILLER, at a draft of 19 feet, has a KGL of 59.91 feet and an LCG of 1.57 feet. What is the trim angle?
AI Explanation
The correct answer is B) 0.3° by the stern.
To calculate the trim angle, we can use the formula: Trim angle = arctan((LCG)/KGL), where LCG is the longitudinal center of gravity and KGL is the vertical distance from the keel to the center of gravity.
Given the values provided:
LCG = 1.57 feet
KGL = 59.91 feet
Plugging these values into the formula, we get:
Trim angle = arctan(1.57/59.91) = 0.3° by the stern.
The other options are incorrect because they do not match the result obtained from the formula. Option A (0.2° by the stern) is too small, while options C (0.4° by the stern) and D (0.5° by the stern) are too large.
