The roar is different. If you’ve never stood on the banks of the Columbia River when a turbine engine screams past at 200 miles per hour, you haven't really heard noise. It’s a physical thing. It vibrates in your chest. For folks in Kennewick, Pasco, and Richland, the Tri Cities boat races—officially known as the Columbia Cup—are basically a secular holiday.
Every July, the population of the region feels like it doubles overnight. People stake out their spots on the grass days in advance. You'll see "Blue Bridge" traffic backed up for miles, and honestly, the smell of sunscreen mixed with barbecue and methanol is just the scent of summer here. But what’s actually happening on the water is a high-stakes, multi-million dollar gamble involving physics that shouldn't really work. These boats are basically planes that are terrified of flying.
The Physics of Staying on the Water
An Unlimited Hydroplane is a weird beast. They’re 30 feet long, weigh over 6,000 pounds, and are powered by Lycoming T55-L-7C turbine engines—the same ones used in Chinook helicopters. When you see them hitting the straightaways during the Tri Cities boat races, they’re only touching the water at three points.
It’s a balancing act. If the nose gets too much air, the boat "blows over." If it gets too little, it "stuffs" into a wave. Both are terrifying.
Why the Columbia River is Unique
The Lampson Pitts Memorial course is legendary among drivers like J. Michael Kelly or Andrew Tate because the water isn't "dead." It moves. You’ve got a current flowing downstream toward the McNary Dam, and when the wind kicks up through the Columbia Gorge, it creates "rollers." These aren't just ripples; they’re swells that can toss a boat like a toy.
The strategy here is different than at the Seafair in Seattle or the races in Madison, Indiana. In the Tri-Cities, the lanes are wide, which invites more aggressive deck-to-deck racing. You can't just hide in the inside lane and hope for the best. You have to fight for it.

The HAPO Columbia Cup by the Numbers
Let's talk scale because people often underestimate how big this event actually is for Eastern Washington.
- Attendance: We aren't talking about a few thousand people. Over a typical weekend, the Water Follies event draws between 65,000 and 70,000 spectators. That’s more than the capacity of many NFL stadiums.
- Speed: The qualifying laps often exceed 160 mph average, with top speeds on the backstretch hitting 190-200 mph.
- Economic Impact: Local tourism boards, including Visit Tri-Cities, have historically estimated the economic injection to be around $3 million to $5 million for the local economy in just three days. Hotels from Hermiston to Yakima fill up.
- Safety: There are over 100 rescue divers and personnel on standby. These guys can get to a flipped boat in under 60 seconds.
The Heat Races and the Saturday Grind
Saturday is when the "real" fans show up. Friday is for qualifying—it's cool to see the raw speed, but Saturday is the chess match.
The heat races determine who gets the best lanes for the final on Sunday. If you finish poorly on Saturday, you’re stuck in the outside lanes, which is basically a death sentence for your chances of winning the trophy. You’re hitting the "rooster tail" of the lead boat. A rooster tail is a massive wall of water thrown up by the propeller that can be 300 feet long and weighs several tons. If you drive into one, it’s like being hit by a fire hose. It can crack a canopy or kill an engine instantly.
It’s brutal.
What People Get Wrong About the Shoreline Experience
If you’re planning to go, don’t just buy a ticket and show up at noon. You’ll be staring at the back of someone's tent.

The "State Park" side (Pasco) and the "Columbia Park" side (Kennewick) have totally different vibes. Kennewick is where the pits are. If you want to see the crews working on the engines or smell the grease, that’s your spot. Pasco is a bit more laid back, usually better for families who just want to park a truck and watch from the bed.
Pro tip: Bring a radio. You can’t hear the announcers over the engines. Most locals tune into the live broadcast on KONA or similar local stations to know why the yellow flag is out. Otherwise, you’re just watching fast boats go in circles without knowing who’s actually winning on points.
The Evolution of the Sport
Honestly, some people miss the old days of the piston-powered "thunderboats." The Allison and Rolls-Royce Merlin engines had a deep, guttural growl that the modern turbines just don't have. The turbines sound like a giant vacuum cleaner.
But the speed? The turbines win every time.
The sport has also become much safer. In the 1980s and earlier, drivers sat in open cockpits. If the boat flipped, they were often thrown out or trapped. Today, they sit in reinforced F-16 fighter jet canopies with oxygen supplies. When a boat like the U-1 Miss HomeStreet or the U-91 Miss Goodman Real Estate hits a wake and goes airborne, the driver has a much higher survival rate than they did thirty years ago.

Beyond the Hydroplanes: The Air Show
It isn't just about the water. The Tri Cities boat races are officially part of the "Water Follies," which includes a massive air show component.
We’ve seen the F-35 Heritage Flight, A-10 Warthogs, and vintage P-51 Mustangs. The geography of the river valley acts like a natural amphitheater for the jets. They pull vertical right over the river, and the sound echoes off the hills of Horse Heaven Hills. It’s loud. It’s American. It’s exactly what you’d expect from a mid-summer festival in the desert of Washington.
Actionable Insights for Your First Trip
If you’re heading out to see the Tri Cities boat races, don't be a rookie.
- Hydrate or Die: It’s often 100 degrees Fahrenheit in the shade. The Columbia River reflected sun will burn you in twenty minutes. Bring a gallon of water per person.
- The "Hole Shot" Matters: Watch the start. The race isn't won at the finish line; it’s won in the final 30 seconds of the countdown to the start. If a driver times it perfectly and hits the start line at full speed just as the clock hits zero, the race is basically over.
- Check the Schedule: The schedule changes constantly due to wind. If the "whitecaps" appear on the water, they’ll pause the racing. This is a great time to hit the food vendors. Get a gyro or a corn dog; it’s tradition.
- Pit Passes: They are worth the extra $10-$20. Standing next to a 30-foot hydroplane makes you realize just how massive these machines are. You can see the carbon fiber hull and the tiny steering wheel that controls all that power.
- Parking: It's a nightmare. Use the shuttle buses from the local high schools or malls. It'll save you two hours of frustration.
The Tri-Cities doesn't have a professional NFL or MLB team, but for one weekend in July, this is the center of the sporting world in the Pacific Northwest. It’s chaotic, hot, and loud. It’s also the most fun you can have on a riverbank.
Check the official Water Follies website for the specific race dates this year, as they usually fall on the last full weekend of July. Get your tickets early, because the "Event Footprint" sells out fast. If you miss the big boats, the Grand Prix West hydroplanes (the smaller, piston-powered ones) often put on an even better show because they race closer together. Don't leave until the final heat of the day—that's when the drivers stop playing it safe and go for the trophy.
