The Helite Tsunami (English: Tidal Wave) is a French high-wing, single-place, rigid-wing hang glider that was designed by Gérard Thevenot and produced by La Mouette under the Helite brand.

Thevenot decided to market it under his Helite brand which was also used for a line of powered parachutes.
[1] The aircraft is made from tubing, with the wing covered in Dacron sailcloth.
[1] The Tsunami won a number of hang gliding championships in the rigid wing class.
