People often think that I must be a multihull hater, just because I own a monohull.
Not true, I love well-designed catamarans (and tris, too) like this way-cool Chris White 42.
But here’s the key point:
To be safe, and deliver on their speed potential, cats must not be overloaded.
Check out how thin the hull of this same cat is. It won’t take a lot of weight to push this hull dangerously low in the water.
Overload this boat, and she won’t be much faster than a mono, and, counterintuitively, will be much more likely to end up upside-down than if kept light.
So to have a safe cruising cat, and to be able to carry a reasonable load of cruising comforts, we will often need a bigger cat than we might at first expect.
