Luigi Castoldi, founder of Castoldi Company and other world renowned Companies such as B.C.S. and Mosa was an ingenious and acclaimed engineer. At the age of 24, he designed a racing boat which, with his brother Achille at the helm, won the 1930 World Speed Record in the 100 HP outboard category.
In the early 60s he revolutionized the waterjet propulsion system.
Mario Castoldi designed the Macchi Castoldi "M.C. 72" hydroplane, which won the Schneider Cup and set the world water speed record of 382,94 knots, which remains unbeaten.
Achille Castoldi, 5 times world champion and world speed recordman 800 Kg Racers class in his "Arno XI" Timossi boat / Ferrari engine F1 : 131,51 knots. Record still unbeaten.
Franco Castoldi won the offshore race Santa Margherita - Montecarlo - Santa Margherita. He travelled 200 nm at an average speed of 57,2 knots with an Enfield 37' boat equipped with two 600 HP engines and a special twin stage counter revolving waterjet drive, designed by his father Luigi Castoldi.
This is, to-date, the only long-distance offshore race in the history of motor boating to be won by a boat having something other than a propeller as its propulsion system.
