Etienne St-Laurent

Owner | Mechanical Engineer

After spending 10 years in the motorsport industry, calibrating engines for racecars, Etienne has turned his passion for speed on the roads to speed on the water. And we’re not talking only about the powertrain.

On the water, understanding how boats perform in all aspects of their design is crucial. Etienne has personally turned two sailboats into fresh water race winners at the world’s longest continuously run long distance freshwater yacht race – the Bayview Mackinac Race on Lake Huron.
