ABSTRACT:
A keel guided acrobatic kite and control apparatus are disclosed in which a reference point included on the keel of the kite is maintained no more than a fixed maximum distance from reference locations included on the body of the kite. Stabilizer lines are secured between the reference location on the keel and each of the reference locations on the body. When the kite is in a nominal flying position, the keel is disposed essentially perpendicular to the body of the kite, and the stabilizer lines are taut. Two control lines are received by guidance structure connected to the reference location of the keel. One end of each control line is secured to one of the reference points on the body. In operation, one of the control lines is pulled, causing the reference point on the keel to move toward one of the reference points included on the body. The stabilizer line connected to that reference point slackens while the other stabilizer line remains taut. The keel forms a pocket extending toward the taut stabilizer line, changing the aerodynamic properties of the kite, and causing the kite to turn.
