Which is the prime function of the bilge keel?

🔍 Key Concepts

• Bilge keel location and shape on a ship's hull • Difference between strength members (like keel, floors, girders) and stability/comfort devices • Typical ways ships are protected alongside a dock (fenders vs fixed structure)

💭 Think About

• Think about where the bilge keel is fitted on the hull and what motion of the ship it would most affect. • Which part of the ship would normally be considered the main strength member running along the bottom? Is that the same as a bilge keel? • When a ship is tied up to a pier, what normally makes first contact with the pier—the bilge area or the side shell/fenders?

✅ Before You Answer

• Be clear on the difference between structural strength and motion control functions. • Visualize a ship at sea in waves: which component would help resist rolling from side to side? • Consider whether bilge keels are designed to routinely touch the pier, or if separate equipment (like fenders) is used for that.
