Timber rafts are used in Southeast Alaska and the Pacific Northwest to cheaply transport whole logs by water. Timber rafts can be of enormous proportions, sometimes up to 600 metres (2000 ft) long, 50 meters (165 ft) wide, and stacked 2 metres (6.5 ft) high. Such rafts contain thousands of logs and tug boats are used to pull and maintain control. Read more here and here. See a short video of a log raft being pulled by a small tugboat here.
