The tank is “athlete powered”, meaning the water is still when athletes are not rowing. When they row, the athletes generate a flow which simulates the feeling of being on moving water when they row. Most splashing will be contained by the splash guards. The rowers sit on seats mounted on the floor; only the blade dips in the water. You will see that the blades are slightly smaller than regular oars. The blades are specially designed by our supplier, Dreher, to achieve the closest feeling to being on moving water.
