The eight-hours' natural draught trials of the first-class torpedo gunboat Speedy (length 230 feet between perpendiculars, beam 27 feet, draught 12 feet; displacement 810 tons) fitted with two inverted-vertical triple-expansion marine engines, built by John I. Thornycroft and Co., Chiswick, for the British Government were conducted in early October, 1893. The Speedy's engines developed 3043 indicated horsepower during the trials, and were a decided success as the contract was for 2500 indicated horsepower with an air pressure of a half an inch of water gauge in the stokehold.
