On some catamarans you get an irritating slapping of water on the bridge decks in rougher seas.
Is a catamaran faster than a monohull. Catamarans have a lot more space below decks and if youre as interested in socialising as you are in sailing you may choose the cat for the luxury and comfort. Its just that tris are typically designed with more. Your speed is very dependent.
Even when powered up a cat or tri will rarely heel more than 5-10 degrees before its time to reef. They also offer safer anchorage and are easy to control. And without the slapping that some catamarans with low bridge decks often produce.
The most noticeable thing about sailing a catamaran or trimaran vs a traditional monohull is the lack of heeling. A catamaran is faster than the average monohull boat. Because most cats draw 4 feet or less of water they can anchor in places a monohuller could not even consider.
While a catamaran is still faster than a monohull of identical size it falls short of the trimaran in terms of sheer speed. A monohull is generally faster to respond to the helm in other words they turn faster. A catamaran is much better than a monohull in many ways.
Cat will have 4 large. If capsized it wont right itself. There isnt enough headroom for people over 6ft tall in most cats under 40ft.
Besides there is ample headroom everywhere. Catamarans are more stable faster and spacious. Gone are the days.
