The four races of the 12-liter class for the world title are divided as follows: two in Europe (in Italy in Venice and in Switzerland in Geneva) and two in the USA.
Theo Rossi and his splendid Alagi write their name for the first time in the roll of honor of the class, thus becoming the first Italian world champion of powerboating. Thanks to the successes in Venice in the Coppa Re Imperatore, Coppa Città di Ginevra and the wonderful victory at the Gold Cup in Detroit, our champion makes the title his.

The other American race on the waters of the Potomac, the President's Cup Washington, has only an Italian pilot at the start, hence the decision not to participate. After winning the world championship, the American President Roosevelt congratulates Theo Rossi by inviting him aboard his yacht.

In 1938 the Italian Agostino Morandi, aboard his Augustus III (Quaroni shipyard hull with BPM engine) takes the world title for the 400-kilo racers category.
With the same Isotta Fraschini engine as the Alagi , the engineer Guido Cattaneo, at the helm of another Baglietto, a very interesting complex equipped with a particular inboard-outboard transmission with counter-rotating propellers, spaced from the stern drive shaft named ASSO, establishes in Arona (Lake Maggiore) the new world record for the 1200-kilo category with over 150 km/h.
