Question 1 of 27070

As a ship moves through the water, it causes a wake, which is also moving forward relative to the sea. In addition to a fore and aft motion, which direction will the wake flow?

🔍 Key Concepts

• Ship’s wake and pressure distribution around the hull • How water displaced by the bow must return to fill in behind the stern • Difference between surface wave pattern (visible wake) and subsurface flow of water

💭 Think About

• Picture the hull moving ahead: what happens to the water pushed aside at the bow—where must it go after the ship passes? • Consider conservation of mass: if water is pushed away from the hull near the surface, how does it return to its original level and position? • Think about whether the flow next to the hull is drawn toward the centerline or pushed away from it as it moves aft.

✅ Before You Answer

• Distinguish between the visible surface wave pattern and the actual flow of water particles under the surface • Decide if water around the hull tends to move toward the hull or away from it as it travels aft • Consider whether the displaced water must move upward or downward to fill in the space left behind the ship
