HAPO Columbia Cup

From HAPO Columbia Cup Website:

The 2014 HAPO Columbia Cup will mark the 49th time Unlimited Hydroplanes have raced on the Columbia River. This years event, like the inaugural in 1966, will most likely have 12 Unlimiteds in attendance. But the modern Unlimited Hydroplane has very little in common with those first boats that churned the waters of the Columbia River. The hydroplanes of 2012 are almost more plane than hydro. They are thirty foot long, 7,000 pound wings that glide over the water with only the bare minimum of the boat making contact with the river. Powered by Turbine engines capable of nearly 3,000hp, the boats can reach straightaway speeds close to 200 miles per hour. Qualifying lap averages in the mid 160mph range are common with the faster boats in the fleet. To put it in simpler terms, at speed, an Unlimited Hydroplane will travel more than the length of a football fields in the space of a second.

The other unique quality of the hydroplane is the wall of water it throws in its wake. Called a roostertail, it trails hundreds of feet behind the boat and represents a unique obstacle to the racers on the course. Getting too close to another boats roostertail can result a boats engine getting clogged with water and stalling. That represents the best case scenario. Taking a full blast of another hydroplanes wake can results in thousands of dollars of boat damage.
