Absolutely Steve, the kids had loads of fun back in the day on towables, kneeboards, wakeboards etc behind our sibs with 20 horse motors.
The Demon/Airhead style toys are not that draggy so will be fine behind a sib. They’re also steerable and often the go to choice with our kids. Great fun.
Steve, not on a Demon but here’s No 1 son getting a soaking behind our old Zodiac/Suzuki 20 combo. Two up in the boat and still plenty of Ooomph!
