In most cases, when a large merchant vessel enters shallow water at high speed the __________.

🔍 Key Concepts

• shallow water effects (squat) on a ship moving at higher speeds • how water flow under the hull changes in restricted depth versus deep water • the relationship between speed, under-keel clearance, and maneuverability

💭 Think About

• Think about what happens to the flow of water under the hull when the water depth is only a little more than the ship’s draft. Does the ship get more or less support? • If the ship moves faster in shallow water, does the pressure under the hull increase or decrease? How would that affect the ship’s vertical position in the water? • Consider how shallow water affects turning ability and stopping distance. Does it usually make the ship easier or harder to maneuver?

✅ Before You Answer

• Review the definition of squat and whether it refers to the vessel moving up or down in the water. • Consider whether both ends of the ship (bow and stern) are affected equally by squat, or if one end is usually more affected than the other. • Verify whether speed in shallow water typically increases or decreases, and how that ties into safety and maneuvering limits.
