🔍 Key Concepts

• Bilge keels location and shape on a ship’s hull • The main cause of rolling motion and how it’s controlled • Difference between structural reinforcement parts (garboard strake, sheer strake) and appendages

💭 Think About

• Think about where bilge keels are fitted on the hull and what type of motion they would affect most directly • Ask yourself: do these structures mainly guide water flow for steering, strengthen specific plates, or resist a particular type of motion? • Consider what part of the ship’s movement would cause the bilge keels to move most through the water, creating resistance

✅ Before You Answer

• Know what the garboard strake and sheer strake actually are and where they are located on the hull • Visualize a ship rolling from side to side and what happens at the bilge area under water • Decide whether bilge keels are primarily a hydrodynamic device (affecting motion through water) or a structural stiffener for specific strakes
