5-Liter Hydroplanes

The Tri-City Water Follies is delighted to announce that the Columbia Cup/Over the River Air Show will welcome back the 5-liter class hydroplanes to its lineup of exciting boat racing on the Columbia River July 28 – 30, 2023! These incredibly fast 5-liter hydroplanes replaced the small 1-liters that have run here in years past.

“These are bigger and faster race boats, but they are still small enough to take the corners very fast. They are a lot of fun to watch”, said Kathy Powell.
