Now that is cool!
Not sure what craft like these would be classified as - not quite a hydrofoil, but not quite a "Wing In Ground Effect" (WIG or WIGE) craft either.
Another use for Copplestone's 28mm pilot figures - the head-and-shoulders-only ones designed for cockpits.
A two-place one - perhaps with a WW1-style machine gun mount around one cockpit - would also be very cool to see!
