Some of what you can expect to see along the 2.5-mile course off the shores of Detroit's Belle Isle this weekend includes:
Unlimited hydroplanes, the fastest and most-powerful closed-course boats in the world, will be racing at speeds in excess of 200 mph;
Grand Prix boats with big-block engines producing some 1,300 horsepower will be hitting speeds of 170 mph;
And Formula II "tunnel boats" will hit speeds of 115 mph.
The Detroit River played host to its first sanctioned hydroplane race in 1916. The races took a hiatus during World War II, but have otherwise been an annual event.
The APBA Gold Cup, first presented in 1904, is the ultimate motorsport prize, considered the most prestigious powerboat racing trophy in the world. The Gold Cup began its relationship with Detroit more than 100 years ago and it is the oldest annual unlimited hydroplane race in the world.
