Q

The horizontal port, or starboard movement of a vessel is called __________.

🔍 Key Concepts

• Body motions of a vessel in 6 degrees of freedom (surge, sway, heave, roll, pitch, yaw) • Difference between motions fore-and-aft, athwartships (sideways), and vertical • Meaning of horizontal movement vs rotation about a vertical axis

💭 Think About

• Which term describes a side-to-side motion straight across the vessel, without turning its heading? • Which terms in the list are actually rotations rather than straight-line movements? • Of the remaining choices, which one is associated with motion along the vessel’s fore-and-aft (longitudinal) axis and which with the vertical axis?

✅ Before You Answer

• Identify which motion is sideways translation (athwartships) of the hull • Identify which motion is forward-back translation (along the keel) • Identify which motion is up-and-down translation (vertical)
