When the jumper hits the ramp they will generally be going over 112 kilometres per hour (70 mph) and the load they have generated on the rope can be over 600 kilograms (1,300 lb). Speeds vary by classes but can reach up to 200 km/h. "[17] The rope and handle are anchored to the boat and played out at the stern. Competition speeds have a wide range: as slow as 22 km/h (14 mph; 12 kn) up to 58 km/h (36 mph; 31 kn) for slalom water skiing, and approaching 190 km/h (120 mph; 100 kn) in water ski racing.[13].
