3 Things to Know about the Columbia Cup
The HAPO Air Show and Columbia Cup are approaching with a roar! Join us as the shores and waters around the Columbia River fill up with fans.
The hydro races have been thrilling fans for many decades but may be new to you. What makes them unique, and why are so many people flooding to the shores of Columbia to see them race?
Here are three things to know about hydroplane racing:
1. The hydros are essentially boats that fly. The design is such that very little of the hull (bottom) touches the water, and the boat mostly races on an air cushion.
2. The hydroplanes race at over 220 miles per hour. The unlimited hydro is about 30 feet long, 14 feet wide, and can weigh about 6,000 pounds.
3. The engines have evolved over the years but mostly come from the aviation industry. For the first few decades after World War II, they used WWII-era internal-combustion airplane engines, typically Rolls-Royce.
