Question: Why does a wakeboarding boat make it easier to jump?
About the article "Wakeboarding", section "Boats".

Candidate passages:
The most common difference between a regular runabout and a wakeboarding boat is the wakeboard tower, normally constructed of thick-walled stainless steel or aluminum tubing, which places the "pull point" about off the water's surface.
The high tow point makes it easier to jump and get air as the rope is not pulling downward as when it is attached to the low tow point used for skiing.
Most modern wakeboarding boats also have a variable ballast system, which allows for water to be pumped into and out of ballast tanks from the surrounding water.
Adding ballast increases displacement, and consequently enlarges the wake produced.
A significant portion of wakeboarding boats utilizes V-drive propulsion.
These boats have a regular inboard engine, but are turned 180° such that the transmission is in front of the engine, rather than behind, or "inline", which is a more common layout for inboard tournament ski boats.
The prop shaft exits the transmission towards the rear of the boat, so that the prop is placed directly under the engine.
When viewed from the side, such a layout appears as a "V" lying on its side.
This layout allows for better weight distribution(with the engine farther aft), and places the prop farther forward, reducing the danger of the spinning prop near the stern of the vessel, where riders enter and exit the water.
Wakeboarding is a surface water sport which involves riding a wakeboard over the surface of a body of water.
It was developed from a combination of water skiing, snowboarding and surfing techniques.
The rider is usually towed behind a motorboat, typically at speeds of 30–40 km/h (18-25 mph), depending on the board size, rider's weight, type of tricks, and rider's comfort.
This speed could also depend on the year, make, and model of the boat because some boats, which are not designed for wakeboarding, create a different size wake which the rider may not feel comfortable with.
But a wakeboarder can also be towed by other means, including closed-course cable systems, winches, and personal water craft. 
Scurfing is a form of water skiing that uses a surfboard or similar board instead of skis.
The scurfer is towed behind a motorboat at planing speed with a tow rope similar to that of knee boarding and wakeboarding.
It shares an advantage with kneeboarding in that the motorboat does not require as much speed as it does for water skiing.
Scurfing is a (towsport) it is very similar to water skiing.
The scurfboard, however, is a surfboard and is usually shorter by about two feet, wider and has three larger fins that make the board easier to manoeuvre while being pulled behind a boat.
The planing speed of the motorboat is equivalent of the speed generated by a wave, and allows the scurfer to ride behind the boat the same way a surfer would ride a wave.
An advantage of scurfing to surfing is that when the surf is flat a scurfing is still possible.
Scurfing can be done behind a boat or a jet ski on a river or the ocean.
The manoeuvres on a scurfboard are much the same as that of the surfboard, these include.
cut-backs   180  360  aerial jumps  power slides  freeriding  Freeriding is when the wake is surfed without the rope.
First the rider pulls themselves up the rope so that they are scurfing in the largest part of the wake.
The rider then gently pumps the board to maintain speed and moves their weight further forward to help them stay on the wake wave.
Once they are being propelled by the wake the rope is thrown back into the boat.
Scurfing has developed into its own unique sport but has also been used in adapting other sports such as surfing.
Before scurfing was invented there were limitations to paddling onto larger waves when surfing because surfers lacked the speed needed to stay in front of the wave.
Scurfing has shown the world the potential of big wave surfing by towing the surfer into big surf.
Therefore giving the surfer the speed needed to catch the wave successfully. 
The Claytor Lake Adventure Base is an aquatics base, which opened in the summer of 2008 making it the newest camp on the Blue Ridge Scout Reservation.
It is situated on the Claytor Lake.
At the base, Scouts spend the week motor boating, large boat sailing, small boat sailing, water skiing, kayaking, snorkeling, rowing, and wakeboarding.
The program offers Scouts the opportunity to participate in an overnighter on a large sailing vessel, where they’ll depart the base, drop anchor, and spend the night out on the lake.
Scouts who are age 14 and older can choose to focus on scuba diving, where they’ll earn a PADI scuba certification during the week.
The Base also offers a wakeboarding school, for Scouts interested in honing their skills in wakeboarding.
The Claytor Lake Adventure Base is renowned for its impressive facilities, progressive programs, and excellent food.
It is a provisional program, offering leadership for Scouts aged 13 and older.

The Air Nautique line up of boats is Correct Craft's wakeboarding package.
This means that the boat is outfitted for wakeboarding with a tower and ballast tanks from the factory.
The first Air Nautique was built in 1997, it was built off of the existing Sport Nautique Hull and had an automatic rear ballast system (Launch Control System or "LCS").
Other notable "landmarks" included Correct Craft's patented Flight Control Tower, which was essentially a modified fishing tower.
