Q

The DEEP DRILLER, at a draft of 55 feet, has a KGT of 53.05 feet and TCG of 0.5 foot to starboard. What is the list angle?

🔍 Key Concepts

• Formula relating list angle, TCG (Transverse Center of Gravity), and GMt (Transverse Metacentric Height) • How to use KGT and draft to find GMt (hint: think of KG vs KMt)** • Need to use trigonometry (tan of the angle) when list is caused by an off-center CG

💭 Think About

• How do you compute GMt if you know KMt and KG? Which of those can you get from the given KGT and draft information? • Once you know GMt, how can you relate it to TCG to find the angle of list using tan(θ)? • After finding the angle in radians or using a calculator, how do you convert it to degrees and compare to the choices?

✅ Before You Answer

• Be sure you are using transverse values (GMt, TCG) and not longitudinal ones • Confirm units: all distances should be in feet, and the angle you compare to answers must be in degrees • Double‑check that you used tan(θ) = TCG / GMt, not the inverse relationship
