Bozeman Paragliding owns two hydraulic payout winches. A hydraulic payout winch is a winch which adds tension to the towline by gently increasing oil pressure in a motor attached to a spool of line. Hydraulic winches are known for being smooth and accurate for both pilot and winch operator. Not every paragliding school has access to a winch, let alone two. We should all use every chance we get to go towing, as it's an important part of the sport of paragliding!
As a pilot at the end of the towline, launching is very similar to launching from a hillside - we either do a forward or reverse launch, depending on wind strength. When our wing is above our head and ready to fly, we lean forward and accelerate. When the winch operator sees that both wing and pilot are ready to launch, he smoothly adds tension to the towline. This gently lifts the pilot into the air. Once in the air, all the pilot has to do is keep his wing pointed at the truck/boat in front of him. The pilot is in control of when he releases from the towline, which is usually done several thousand feet over the ground. After release, the pilot is free to either find a thermal (over the ground) or practice maneuvers (over the water).
Every year Bozeman Paragliding goes flatland flying. One of our favorite places is Shelby, MT (first two images on right). Shelby is almost perfectly flat, there is a gridded road system for retrieves, and Highway 2 runs east/west through Shelby and across the entire state of Montana. The distance flying is fun and relaxed, as wind direction and speed are less of an issue, and there are no obstacles (mountains) that produce rotor or other tricky micrometeorology. A pilot can search for lift all the way to the ground and once the lift is found, he can simply drift with it wherever the wind is taking him. It seems like every time we go to Shelby with a pilot who hasn't been there before, that pilot gets a personal best distance flight.

The winch in the photo to the right is a permanent fixture in Bozeman Paragliding's tow boat. In addition to being one of the smoothest launching winches, it is also one of the easiest to operate and rewind. It uses a large pressure gauge, a swivelled pressure relief valve knob, and a clutch-pump rewind system. By using the boat engine to rewind the line after the pilot releases, more time is spent watching the pilot instead of starting a noisy gas motor or fishing the drogue chute out of the lake at the end of the rewind. Another product of the clutch-pump system is the tightness of the rewound line on the spool. A tight rewind means no line-digs on the next tow (which can end a tow early, break weak links, and send the line splashing down into the water). We have used this winch since 2005, and so far we've had no issues with the line jumping off of the pulleys, no line-digs, and no clutch pump problems. Having a winch like this keeps the boat driver/winch operator happy. If the driver and tow tech are happy, we're all happy.
Over the water towing is something every pilot should experience. It's usually warm and sunny, we're at the beach all weekend, we camp there, eat there, and entertain ourselves there. The flying is amazing, and the pilots can practice whatever they want with the safety of the lake and rescue boat below them. It's a great chance to let your inner-redneck out and dazzle us with campfire stories and campfire songs.
