The 40 ft hydroplane 'Pioneer' under way. 'Pioneer' was an English boat, owned by the Duke of Westminster, and challenged America for possession of the Harmsworth International Trophy in 1910. Powered by a 12-cylinder Wolseley-Siddeley engine, rated at 400 horsepower, 'Pioneer' initially left the American defender, 'Dixie II', far behind, but unfortunately the engine overheated later in the race. 'Dixie II' took back the lead and retained the trophy.
