This year’s event will take place in the Tri-Cities area over the July 29-31 weekend. Like the inaugural in 1966, this year’s running 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 today are almost more plane than hydro. They are thirty feet long; with 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 generating 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 field 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 boat’s roostertail can result in a boat’s engine getting clogged with water and stalling. That represents the best-case scenario. Taking a full blast of another hydroplane’s wake can sometimes result in thousands of dollars of boat damage.
One thing the 2.5 Mile Columbia Cup course has always been renowned for is speed. Boats tend to post their fastest qualifying times of the year at the Columbia Cup.
This course has been the fastest on the circuit for the last five years. If you want to see the fastest race of the year, attend the Columbia Cup. With the increased speed comes increased danger. A nudge of water from a roostertail, an inopportune roller, or a gust of wind and suddenly a hydroplane might be making an unscheduled appearance in the yearly air show. Fortunately, the safety advances in the sport have shielded the drivers from serious injury during these circumstances.
The action starts Friday evening with Dash for Cash – the top four teams will compete for a generous cash prize. Racing starts Saturday, with two sets of heats and concludes on Sunday with two more heat sets and a Final Heat. The winner not only takes home the Columbia Cup hardware, but they win the coveted parking spot under Bernie Little’s famous tree for the following year’s race.
