How much power do you need for water skiing? |

Towing water toys such as skis and wakeboards need power. It is a good thing that today’s powerboats are up for the challenge. Their engines supply the right amount of horsepower that skiers need to pull their tricks on the water.
Running at 250 to 350 horsepower, today's ski boats have come a long way in terms of engine power and design. They come as powerful, comfortable tow boats with speed-control packages, electronic engine-management modules and sound systems.
Measuring 16 feet to 24 feet, ski boats are usually powered by a gasoline, 4-cycle, V-8 engine, as a straight inboard direct drive system. Ski engines can cast a perfect wake for very serious water skiers.
The sport of water skiing itself is not new; in fact it is almost a hundred years old. In the early 1920’s an 18-year-old boy named Ralph Samuelson made his initial attempts to “fly” on water. He first did it by skiing on barrel staves and snow skis but he did not find success until he used pine boards measuring 8 feet long and 9 inches wide.
Skiing has come a long way since Samuelson. It is now a very popular recreational and competitive sport attracting people of all ages. Water-skiing comes in many forms. These include slalom skiing, trick skiing, jumping, knee boarding, ski-boarding, speed skiing, kite flying, show skiing, and barefoot water-skiing.
Developments in technology have improved the design of skis and boats used for towing skiers.
For skis, the design varies from the basic two pine boards to the shorter and narrower slalom ski with a concave bottom. Fat skis, however, are the favorite among beginners. Longer skis with flat bottoms help beginners to get more stable on water and allow them to turn easily.
The shape of the ski varies due to the purpose of the ski. To go faster, skis with sharp edges will help you do the trick. Large tipped-skis allow for skier’s quicker pull up. Fins on other hand makes maneuvering easier.
Boat designers and manufacturers are also responding constantly to meet the needs of the ever-growing skiing market. Aside from boosting power, the engines and propellers of water ski boats have been redesigned to make a smaller wake.
The engines and propellers have been redesigned to make a smaller wake. Skiers prefer less turbulence because it is harder to maintain balance when a big wake causes irregularity on the water.
A water ski would usually feature an open cockpit with a powerful "V-8" engine placed as low as possible in the center of the boat. This engine, coupled with a specifically designed propeller, gets the boat and the skier/wakeboarder up on plane (on top of the water) within a few seconds. Dedicated ski boats generally create low, flat wakes, which are ideal for skiing. Engines that produce less noise and pollution are more ideal for skiers.
The skier can pull different moves and tricks depending on the speed of the boat. The faster the boat travels, the easier it is for the skier to stay up on the water. To keep a 150-pound adult up on water ski, the ski boat should be running about 32-40 kilometers per hour (20-25 miles per hour).
