The Monocat plans are available for purchase here:
The Monocat was not a scaled hull of a catamaran, but rather a Marblehead hull designed after one hull of a catamaran.
The boat was designed for minimum wetted surface and hullform resistance, which is why the idea came from a Cat.
The hull ended up with anti-dive rails along the sides of the bow.. Which should tell you it's major downfall in inconsistencies when competing at high level events.
It should still be a very fast boat, but any builder should be weary of it's downwind performace with a super-high-aspect ratio rig.
