The Elfe series started from a 9 m sailplane designed by W.Pfenninger before World War II. A new design was introduced by him in 1947 to become the Elfe 2, probably the first sailplane with a laminar flow airfoil. Subsequently the series was further developed by Markwalder in 1951 to become the Elfe PM-3 (brought to the US in the sixties).
Markwalder had completed the drawings after Ruedi Sägesser had problems with the construction. Pfenninger came up with the idea of the construction.

In 1989 designer and manufacturer Larry Seifert introduced the Mariner. The Mariner is a two-place tandem seating amphibious bi-plane. It was being offered in kit form, which would take the average builder between 300 and 600 hours to build, and required no special tools, or jigging. It was also offered as a ready to fly plane under the new Light Sport Aircraft category.
The Mariner is set up to take a number of different engines, from the Rotax 503 and 582 on up to the Subaru auto conversion. Depending on engine power cruise comes in between 55 and 75 mph, top speed 95 mph, climb rate 1,000 feet per minute and stall 28 mph. Take off from land or water requires 150 to 200 feet.
