Sports spotlight | Okawa’s favorite number is 80
TU/e boasts a total of 38 student sports associations. And every one of them offers its own unique experience: from slamming aces to skimming across the water. At student sports center SSC, you get a wide range of options to choose from: gaming, jumping, running, cycling, rowing, flying, shooting, hanging, playing chess, surfing, punching and pushing. Cursor wants to put every one of these associations in the spotlight. The first question is “What is your favorite number?”
Warming up
Okawa is the only student whitewater kayaking association in the Netherlands that has whitewater as its primary discipline, says Chiel Ton, now a PhD candidate at Electrical Engineering. He has been a member of Okawa for ten years and is now also an assistant instructor. “We don’t consist of a collection of teams, like you see in a soccer association. And kayaking is not a solo sport, as many people believe. No – because we kayak on whitewater, we’re a very close-knit group. You’re often in the middle of nowhere, so you need to keep an eye on each other. You’re seriously responsible for one another’s safety.”
First, Ton shares a fun fact about Okawa members. “We’re all a little bonkers, seeing as we chose to join an association for kayaking on whitewater in the as-flat-as-it-gets Netherlands.” Whitewater can be found in the Ardennes, the Eifel, the Pyrenees, and Slovenia, and Okawa has explored basically every corner of the Alps as well. They also went to Uganda once, but that is now a thing of the past. There are vague plans for the Zambezi, the Grand Canyon, or Norway, “but those are still just dreams”.
Their favorite number is 80 because that’s an ideal water level on the gauge in Monschau, in the Eifel region. That is when the Rur, a rain-fed river in that region, turns into a “roaring stream”, according to Ton. “Many Okawa members get very excited about that and then start wondering whether the lecture they’re supposed to be attending that day is really more important than kayaking on the Rur.”
Scores
- 9.3 cm is the water level at Monschau in May 2025. “Bone dry”
- 80 cm is an ideal water level in Monschau
- Okawa owns 44 boats
- There are 47 members
- The longest trip Ton can remember was 17 kilometers
- Once a year, they organize a summer camp
- Your average freestyle kayak is 170 centimeters long
- A hefty whitewater boat is 273 centimeters in length
- Ton’s shoe size is 46, so you can imagine he has trouble fitting into a freestyle boat
- A new kayak costs more than 1000 euros
- You can buy a second-hand boat starting at 200 euros
- Ton’s boat weighs 25 kilos, including a few liters of water, a first-aid kit and a throw bag
Analyses
Somewhere in Germany (“Eifel or Sauerland”), Ton learned that you shouldn’t do a 17-kilometer trip with inexperienced kayakers in winter. “We wore anoraks over our wetsuits, but it still got really cold after a while. Keeping everyone warm was a real challenge.”
The shape of the boat determines how the water gets a grip on you and how you get a grip on the water. The shorter the boat, the more maneuverable it is. The longer it is, the faster it goes. So a freestyle boat, which you can use to do a cartwheel (a sideways spin with the boat) or a flat spin (turning the boat 180 degrees), is a short boat. And a small boat also has a narrow bow. So the fact that Ton’s kayak is 273 cm long doesn’t just mean it’s fast, it’s also convenient for his size 46 feet.
