Even though bilge keels do provide some improvement in longitudinal strength at the bilge radius, what is the primary purpose of the bilge keels?

🔍 Key Concepts

• Function of bilge keels in ship motions (roll, pitch, yaw, heave) • Location of bilge keels on the hull and how they interact with water resistance • Difference between longitudinal and transverse ship motions

💭 Think About

• Which type of motion causes the ship to alternately lean from side to side, immersing first one bilge area then the other? • Given where bilge keels are located, in which motion do they create the most drag and resistance in the water? • Think about which motion is around the ship’s longitudinal axis versus its transverse or vertical axes.

✅ Before You Answer

• Identify what motion is associated with the ship’s longitudinal axis (bow to stern). • Picture the ship from the front: which motion makes the bilge area move up and down through the water on alternating sides? • Eliminate options that involve motion where the bilge area is not moving significantly sideways through the water.
