Boats

Boats vary in proportions and construction methods according to their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style, partly to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats, and sailboats. Houseboats may be used for vacationing or long-term residence. Lighters are used to move cargo to and from large ships unable to get close to shore. Lifeboats have rescue and safety functions.
