Your vessel has run hard aground in an area subject to heavy wave action. Backing full astern failed to free her. Which action should be taken next?

🔍 Key Concepts

• Grounding in heavy wave action and risk of pounding or "inshore creep" • Effects of changing trim (shifting weight fore and aft) on where the ship is touching bottom • Risks of prolonged backing or increasing bottom pressure when already hard aground

💭 Think About

• Think about what heavy seas and waves do to a vessel that is firmly aground near the beach or shoal. Does she tend to move shoreward or seaward? • Which option best reduces damage and helps the ship work free over time, rather than increasing stress on the hull or driving her further aground? • How does shifting weight or flooding tanks change the contact area and pressure on the seabed?

✅ Before You Answer

• Identify which choices increase bottom pressure and hull stress versus which reduce it • Consider which action reduces the tendency to creep farther inshore in heavy surf • Ask which option a salvage master would likely avoid because it might worsen damage or make refloating harder

Shift weight aft to reduce the forward draft.

Flood empty tanks to increase bottom pressure and prevent inshore creep.

Continue backing to scour out the bottom.

Wait for high tide and then try backing.
