(the basis for this article was taken from Embassy Grand Prix Programme 1977)
Soon after WWI, under the unrealistically costly shadow of building and entering unlimited engined boats for the Harmsworth Trophy, a small group of enthusiasts decided to develop a class of boat costing no more than £300, by limiting the engine capacity to perhaps, 1.5 litres.
In 1922, Mr Jack Brooke of Lowestoft (uncle to Tom Percival) built the world’s very first 1.5 litre powerboat – a 30hp, 15ft hydroplane called Mr Poo with a maximum speed of 28.25 knots.

In 1971 the Italian ace and current World Formula 1 champion, Renato Molinari, won the trophy, with Britain’s Bob Spalding winning it the following year. 1973 saw the first mighty unlimited Rotary engines from OMC, and it was with one of these that the American team of Mike Downard and Tom Posey captured the trophy.
