A waterslide defined by a trough proceeding generally downhill and carrying water to be skimmed over by a rider, is arranged with successive uphill and downhill sections at a crest. Water injection ports along the uphill section approaching the crest are inclined in the direction of motion and assist slower riders over the crest. The same ports can direct sufficient water over the crest for braking faster riders along the downhill section. A portion of the water injected along the uphill section flows backwards to a low point. An elongated drain at the low point prevents pooling of water tending to slow down the riders. A pad for supporting the rider while traversing the waterslide has a U-shaped bow support web disposed at a front of the apparatus, with spaced legs extending rearwardly and an integral handle graspable by the rider. Two integral web and handle members are wrapped part way around by the leading edge of the pad and attached thereto by push pin fasteners.
