Setting out with the goal of building the most efficient boats we could, our founder Larry Graf and his designers sought to create earth-friendly cruisers that would inspire a new generation of boaters. And because Larry and his team played a hands-on role in developing some of the world’s best catamarans, they had an idea of what a boat could be in terms of comfort, stability, and fuel economy.
Knowing what we already knew about catamaran hull design and the many inherent benefits of multihulls, we began to explore a dual hull boat that would be different from a traditional catamaran.
What we found is the asymmetrical hull catamaran. This revolutionary hull design is called a proa and it exhibits certain benefits for power catamarans, aside from the obvious stability that is a key advantage of a catamaran over a monohull. The two hulls are identical in profile, but they are actually very different in shape—with one hull being 35 percent thinner.
