Even though sea journey is usually associated with ships, the oldest means of sea transport were often in the form of smaller crafts, like boats or rafts. Such vessels obviously had limited use, but one should not underestimate their ability to aid entire cultures in their migrating efforts. The most famous example for extensive use of small craft were the Polynesian people, who colonised a vast area of the Pacific Ocean with outrigged canoes led by skilled navigators. The sturdiness of these vessels was confirmed by the great experiment performed by Thor Heyerdahl in 1947, whose raft named Kon Tiki successfully sailed from Callao in Peru to the Tuamotu islands.
