I just Googled Harris-Kayot Catamaran and Google brought me back to your post on Winni.com....however I did come up with this.

It's NOT a Catamaran but a modified "V" hull with the Volvo O/D. A SINGLE
Outdrive Powered Catamaran would be problematic. To be practical, a catamaran hull would need TWO outdives..One in each hull.
Harris-Kayot also seems to make conventional aluminum
Toon Boats.
