Question 1 of 27070

The DEEP DRILLER, at a draft of 50 feet, has a KGT of 52.12 feet and TCG of 0.5 foot to port of the longitudinal centerline. What is the list in feet?

🔍 Key Concepts

• Relationship between tangent of the angle of list and transverse metacentric height (GMt) • How to compute GMt from KGT (KG transverse) and KMt (transverse metacentric height above keel), assuming KMt is known or given in exam tables • Converting an angle in degrees to transverse shift in feet at a known draft or beam

💭 Think About

• What formula links transverse center of gravity offset (TCG), GMt, and the angle of list? Write that down first. • Once you find the angle of list, how can you turn that angle into a sideways displacement at the waterline in feet? What geometric relationship are you using? • Check the direction: if TCG is 0.5 foot to port, which way will the vessel list, and how is that described in the answer choices?

✅ Before You Answer

• Be sure you are using GMt (transverse), not longitudinal GM or a different stability parameter. • Verify that the trigonometric function you choose (sine vs. tangent) correctly matches the right-angle triangle formed by GMt, TCG, and the angle of list. • After computing the list angle, confirm that your conversion to feet of list at the deck edge or waterline is consistent with the vessel’s half‑breadth/beam or draft assumption used in your exam formula sheet.
