A catamaran is much better than a monohull in many ways.

Catamaran vs monohull seasickness. While the Monohulls stability is more easily questioned than that of a catamaran a monohull sailboat requires four times less force to capsize than a catamaran of comparable size. Getting a mechanic to service two engines and sail drives will be more expensive than a comparable monohull with one engine. This is why we stated that a catamaran is good for shallow waters.

A monohull typically sits deep within the water while a catamaran sits much higher on the water. Monohulls are more back and forth and side to side while the catamaran feeling is circular a washing machine like motion. Catamarans cause less chance of motion sickness because they allow for gentler motion and be more predictable.

On a monohull any of these events will breach the watertight integrity of the entire vessel but on a catamaran the strong likelihood is that only one hull will be breached leaving the other hull intact and. There is no question that catamarans are faster under power or sail. Monohulls offer heeling faster steering response less noise from water slapping are cheaper to buy and maintain and have one hull.

Catamarans are usually more expensive to buy or rent and to moor and dock than monohull sailboats but they do offer a lot for their price. Catamarans can be difficult to anchor and take twice as much docking space as a monohull. This means catamarans can get into places monohulls yachts often cannot reach and that they can also anchor closer to shore.

Catamarans usually have a lot more systems engines plumbing electrics etc than monohulls. Although catamarans are fast when sailing downwind monohulls can be faster sailing upwind. They also offer safer anchorage and are easy to control.

There is more more yawing on a catamaran and unpredictability to the motion while a monohull has more specific pitch and roll motion. Cats are more stable faster offer more space and have two hulls. The reduction of seasickness for passengers is one of the most evident benefits of catamaran stability.
