The hull is the main body and watertight shell of a sailboat that provides the buoyancy and stability necessary to keep the vessel afloat. It is the foundation that carries passengers, supports the rigging, and houses internal components.

Key Hull Sections
Bow: The forward or "front" part of the boat, typically shaped to cut through the water.

Stern: The rear part of the boat.

Transom: The flat vertical surface that closes off the hull at the stern; it often serves as a mounting point for motors or rudders.

Deck: The top, generally horizontal surface of the hull that seals the body and provides a platform to walk on.

Gunwale: The upper edge of the hull's side where it meets the deck, providing structural rigidity.

Bilge: The lowest compartment inside the hull where water tends to collect.
