BMW-Oracle Racing Keel

The Racing Keel

The BMW ORACLE America's Cup racing yacht features a state-of-the-art  keel that accounts for 19 of the vessel's 24 legal tons.

BMW ORACLE racing keelDesigning and manufacturing the keel posed an exceptional engineering challenge. Engineers needed to balance strength with maximum hydrodynamic efficiency.

These vibrations transfer to the hull affecting the yacht's structural integrity. To improve the yacht's stiffness, BMW engineers have applied similar technology used in stiffening the companies motor cars. They've also refined the shape and position of the keel wings to increase boat speed.
