Sailboat Keel Diagram - Understanding Boat Stability and Design #3343804 (License: Personal Use)

This schematic illustration depicts a monohull sailboat with a prominent yellow mainsail and a blue hull, clearly labeling the keel as the deep, vertical fin extending downward from the center of the boat. The keel serves both as ballast to counteract heeling forces from the wind and as a hydrodynamic surface to reduce leeway. The cockpit, cabin, and mast are also visible, emphasizing standard sailboat anatomy.
