When making way in heavy seas you notice that your vessel's screw is being lifted clear of the water and racing. Which action will correct the situation?

🔍 Key Concepts

• Propeller racing in heavy seas and its effect on the engine and propulsion system • How trim (weight distribution forward/aft) affects the way a vessel pitches in a seaway • Relationship between ship speed and the bow/stern motion in large following or head seas

💭 Think About

• Which choice would help keep the propeller more consistently submerged when the stern is lifting and dropping in heavy seas? • How would changing speed affect the vessel’s pitching period compared to the wave period? • Would shifting weight forward or aft tend to reduce the stern from lifting clear of the water in these conditions?

✅ Before You Answer

• Identify which actions directly affect trim (fore‑and‑aft balance) versus just steering • Consider which option reduces pitching amplitude and helps keep the propeller in the water • Eliminate any choice that does not physically change either speed through the water or fore‑and‑aft weight distribution
