The main goal of a mechanical self-steering gear is to keep a sailboat on a given course towards the apparent wind and to free the helmsman from the steering job. An advantageous side effect is that the sails are kept in optimal angle towards the apparent wind and deliver optimal propulsion force by that.
The Parasailor has a double-layer wing which inflates as the wind fills the sail. This acts like a soft batten, holding the sail out and actively re-opening the collapsed leech. The wing generates a lift that raises the bow of the boat, and also ensures that there is no loss of propulsion.

There are two 301st wings. The 301st Fighter Wing, which is one of three Second World War wings to be wings (others are 24th and 54th), was revived in 1972 as the overall headquarters for reserve F-105 units. The 301st Bombardment Wing was one of the first wings under the Hobson Plan, and served SAC, ultimately as an air refueling wing until 1992.
Edel Paragliders was a South Korean aircraft manufacturer based in Gwangju and headed by Sung Heon Song. The company specialized in the design and manufacture of paragliders and paramotor wings in the form of ready-to-fly aircraft.
In these competitions, the parasail is towed to a specific height behind a vehicle, and the driver and/or the parasailor releases the tow line to land in a specific target area. The first international competitions for land-based parasailing were held in the mid-1980s and have continued annually since then.
Its 11.8 m (38.7 ft) span wing has a wing area of 23.8 m 2 (256 sq ft), 53 cells and the aspect ratio is 5.8:1. The pilot weight range is 40 to 70 kg (88 to 154 lb).
