Barge
As A Found Form Of Boat A barge is a flat-bottomed ship, built mainly for river and canal transport of heavy goods. Some barges are not self-propelled and must be towed or pushed by towboats, canal barges or towed by draft animals on an adjacent towpath. Barges contended with the railway in the early Industrial Revolution, but were outcompeted in the carriage of high-value items due to the higher speed, falling costs and route flexibility of railways.

A pile driver atop a barge floated on San Francisco Bay and pounded steel piles down to bedrock.
The piles were creating a base for the new Oakland span of the Bay Bridge.
