Cruising Catamarans Offshore
After reading this:
I can say that I understand Catamarans stability better.
Comparing Catamarans with Monohulls, Catamarans are much less prone to be capsized by a wave, but on the other hand they can be capsized by excessive wind, an impossible thing with a modern monohull.
Catamarans are also easier to pitch pole being the main risk factor (to capsize) the conditions where you can find big waves (heel)associated with strong or gustier winds.
