The DEEP DRILLER is level at a draft of 58...

🔍 Key Concepts

• TCG (Transverse Center of Gravity) vs LCG (Longitudinal Center of Gravity) – what direction does each one measure? • What does it mean physically when a vessel is level with no environmental forces (no list, no trim)? • Relationship between symmetry about the centerline and the transverse position of the center of gravity.

💭 Think About

• Ask yourself: does the word "forward" describe a transverse (side‑to‑side) position or a longitudinal (fore‑and‑aft) position? Which center of gravity uses that direction? • If a vessel is floating upright with no list, where must the center of gravity lie in relation to the centerline? • Look at the units and descriptions in the answers: which one is actually describing a transverse location, and which ones are describing a longitudinal location? Make sure you match the right type of center of gravity to the right direction.

✅ Before You Answer

• Be sure you know that TCG is measured port/starboard from the centerline, not fore and aft. • Confirm that "forward of amidships" refers to a longitudinal distance, which is associated with LCG, not TCG. • Before choosing, ask: if TCG were not on the centerline, what observable condition (like list or heel) would you expect, given that the problem says the vessel is level?

The DEEP DRILLER is level at a draft of 58 feet when there are no environmental forces. What is the value of TCG?

0.00 on the centerline

2.23 feet forward of amidships

2.26 feet forward of amidships

2.31 feet forward of amidships
