The DEEP DRILLER has a KGT of 52.90 feet while at a draft of 58.0 feet. List is 2.0 feet to port. What is the value of TCG?
Official USCG Answer & Rule Citation
Correct Answer: Option C — -0.16 foot
Transverse center of gravity (TCG) is determined by taking moments about the centerline. For a given list angle and metacentric height, TCG is calculated using the formula TCG = KG * tan(list) or via cross curves in the DEEP DRILLER manual, resulting in -0.16 foot.
