You can have the hulls designed for efficiency. The most efficient hull is long, sharp, and round bottomed. Because of their more efficient hulls, light weight, and large sail plans catamarans are quite a bit faster than monohulls. They can go 25 knots or more. That's a whole different ball game compared to monohulls.
All cats are sloop or cat rigged with large efficient fully battened mainsails.
Their large efficient sails can get them moving in the lightest of breezes. You rarely see a cat with an aquiliary motor. Most small cats are made to be beached instead of moored, which is very convenient for most people, but can be tough for those who have lakefront with no beach. There is a big range of catamarans available too. Some are simple daysailor types, others are extreme speed machines, and there are many models in between.
