Control is by the normal method with hands on the basetube. Legs are supported by a line and foot stirrup from the carabiner. The base tube is typically 6 inches above the thighs when correctly seated. Flying in a seated position within the confines of the control bar. Feet may rest on a stirrup or on the base tube.
Control is by hands on the uprights.
This position is far less common than supine and requires placing ones feet up and over the base tube after launch and back behind the base tube before landing. Perhaps the best advantage of this method is that the glider's control bar does not have to be re-rigged from the prone position. This is the postion used by the Wills Wing Sky-Floater system utilizing a modified paraglider harness. These technique changes will be easy for most competent pilots. This speed range has been sufficent for all normal flying but will probably not do for all out competition racing.
