Disposable ship

A disposable ship, also called raft ship, timber ship, or timber drogher was a barely seaworthy vessel assembled from large timbers lashed or pegged together for the purpose of making just a single voyage from North America to England where the vessel was subsequently dismantled and its timbers sold piecemeal to British shipbuilders. The disposable ship avoided two problems that adversely impacted profitability of shipping in the British timber trade: high taxes and small cargoes.
