The La Mouette Topless is a French single-place, hang glider that was designed and produced by La Mouette.[1]

Design and development

The Topless was introduced in 1995 and was the first commercially produced modern hang glider without a kingpost and upper flying wires. Intended as a competition glider, it was based on the development work of Christof Krazner.[1][2]

The aircraft is made from aluminum tubing, with the wing covered in Dacron sailcloth. It was built in three different sizes, designated by their metric wing areas and all with a nose angle of 132°.[1]
