You read and quoted too fast. Pay atention:

It was designed to be the first foiled cabin cruiser series in the World...
Williwaw was a
one-off cruising foiler, not a production boat.
The designer of the Catris, Aldis Eglajs, also built other cruising foilers before, including a cruising proa with foils in the 80's, but all were also one-offs.
The first production foiler was either the Rave or the Trifoiler (I am not sure which came first). The Catri is the third production foiler, but the first with a cabin.
I guess they remain the only ones to date (?).
