The Lechner A-390 was an Olympic Class windsurf board for the 1992 Olympics.

[1] It was only raced at the Games that year.

Lechner modified their Division II board to bring the centreboard and mast track further aft.

The rig supplier, Neil Pryde, was decided 3 years before the Olympics.

The supplied equipment stayed with the sailor for the entire regatta as it was expected that each board needed special tuning to the daggerboard system.
