The sailing versions have been built. The "La Hina Ma" (I think I spelled it right) sailing charter boat is a G-Force 36 Sport Cruiser based out of the Seafood Shack marina in Cortez, FL. The owner previously used a Stiletto 30 which he said was constantly breaking down, while th G-Force holds up much better. There was also a Salon Cruiser built. I don't think any power-boat versions were made. Also built and recently up for sale (can't remember where I saw it) was a 40'(?) Trimaran using G-Force 36 hulls as amas.
The sailing versions have center-board style rudders.
