Q

The horizontal fore and aft movement of a vessel is called __________.

🔍 Key Concepts

• The six basic motions of a vessel: surge, sway, heave, roll, pitch, yaw • Difference between translation (straight-line movement) and rotation (turning about an axis) • Meaning of fore and aft versus athwartships (side to side) on a vessel

💭 Think About

• Is the question asking about movement in a straight line or rotation about an axis? • Does fore and aft describe movement along the ship’s length or across its width? • Which motion term is used for side‑to‑side movement, and which for up‑and‑down movement? That helps you eliminate two wrong choices first.

✅ Before You Answer

• Match fore and aft with movement along the longitudinal (lengthwise) axis of the ship • Identify which listed motions are rotational (turning) rather than straight‑line movement • Eliminate the term that describes vertical (up and down) motion before choosing your answer
