PS John H Amos
''John H Amos'' is a paddlewheel tugboat built in England in 1931. The last paddlewheel tug built for private owners, now owned by the Medway Maritime Trust. She is one of only two surviving British-built paddle tugs, the other being ''Eppleton Hall'' preserved at the San Francisco Maritime National Historical Park in San Francisco, California.〔(【引用サイトリンク】title=Eppleton Hall )〕
==Construction==
''John H Amos'' was commissioned for the River Tees Conservancy Commissioners and built by Bow, McLachlan and Company Ltd. of Paisley, Scotland.〔 She was named to honour of the Secretary to the Commissioners, John Hetherington Amos who died in 1934. Before completion Bow, McLachlan & Co. went into liquidation and its yard was taken over by National Shipbuilders Securities (NSS). NSS finished the work by using materials that were already available in the yard, which resulted in a variation to design specification: some parts where therefore better, while others were worse.
On first steaming, it was discovered that the boilers used could not supply enough steam for the diagonal compound engines, meaning she could only reach 11 knots instead of the intended 13 knots. She was completed in 1931 but the Tees Conservancy Commissioners did not accept her for another two years before remedial work was completed to bring her up to design specification.
