Q

The DEEP DRILLER, at a draft of 60 feet, has a KGT of 57.11 feet and TCG of 0.5 foot to port. What is the list angle?

🔍 Key Concepts

• Use the small-angle formula relating TCG, GMt, and angle of list (tan θ = TCG / GMt) • Compute GMt from the hydrostatic data at 60 ft draft using GMt = KMT − KGT • Remember that KGT already includes free-surface corrections, so use it directly

💭 Think About

• From the vessel’s hydrostatic tables at 60 ft draft, what is KMT, and therefore what is GMt? • Once you have GMt, what is tan θ if TCG = 0.5 ft, and what angle in degrees does that correspond to? • Which answer choice is closest to the angle you compute when you convert from radians/degrees and consider small-angle behavior?

✅ Before You Answer

• Verify you are using transverse metacentric height (GMt), not longitudinal GM • Confirm that KGT (not KG) is used in GMt = KMT − KGT for this condition • Double‑check your calculator: make sure you’re taking arctan (TCG / GMt) and converting the result to degrees before matching the multiple‑choice options
