"Wing-in-ground-effect" Any homebuild kits available?

Greetings,

I recall a few years ago several companies that were building
prototypes of ultralight sea-planes that flew in ground effect over
the water. They used fiberglass hulls and tube and fabric control
surfaces.

They were supposed to be classified as boats and not planes since they
were limited to a max altitude of about 10 feet.

Does anybody know of any kits availabe? I've seen a few 5-6 seat
russian models on the web but I'm looking for a simple 1-2 seat
ultralight type craft.

Thanks and Happy New Year
