🔍 Key Concepts

• Beam seas and how they affect a vessel’s side‑to‑side motion • The vessel’s natural rolling period (time for one complete roll from side to side and back) • What happens when an outside force has the same period as a vessel’s natural motion (resonance concept)

💭 Think About

• Is this question asking about motion around the longitudinal axis (roll), transverse axis (pitch), or vertical axis (yaw)? Match each term to the correct axis. • If waves are striking the vessel on the beam (side), which type of motion is primarily excited: roll, pitch, or yaw? • When the wave period matches the vessel’s natural rolling period, does the motion tend to be damped (reduced) or built up (amplified) over time?

✅ Before You Answer

• Be sure you can define roll, pitch, and yaw and link each to the correct axis of motion. • Confirm that beam seas act mainly on the vessel’s sides, not bow or stern. • Think about resonance: when the forcing period (wave period) equals the natural period of motion, the amplitude of that motion usually becomes larger, not smaller.
