Boat building

Each part of the hull has a different name and purpose:
- keel - an important part of the boat's structure which also has a strong influence on its turning performance and, in sailing boats, resists the sideways pressure of the wind
- gunwhale - the sides of the hull are mostly concerned with preserving the buoyancy of the hull by keeping water out
- bow - the front and generally sharp end of the hull is designed to cut through water easily and should be tall enough to prevent water from easily entering the boat
- transom - the rear and generally blunt end of the hull is often designed to carry an outboard motor
- deck - the top surface of the hull keeps water and weather out of the hull and allows the crew to operate the boat more easily
- rudder - a steering device at the back of the hull created by a turnable blade on a vertical axis
- chines - are long, horizontal strips on hydroplaning hulls that deflects downwards, the spray that produced by the hull when it travels at speed in the water
- clinker - overlapping wooden planks are attached to a frame
- carvel - a smooth hull is formed by wooden planks are attached to a frame
- GRP - glass re-inforced plastic is moulded into a hull shape
- inflatable boat - the hull created from air tight tubes that are inflated with air under pressure
- lapstrake - planks are fixed to each other and then a frame built inside the hull
- plywood - sheets of plywood are fixed to a frame built forming a smooth hull
- strip-built - thin, flexible lengths of wood are secured together and reinforced with fiberglass.
- stitch-and-glue - pre-shaped panels of plywood are edge glued and reinforced with fiberglass without the use of a frame.
