There may be some exceptions with dagger boards but overall monohulls have a better upwind performance.
Catamaran vs monohull ocean sailing. If you want to use a diesel motor there is more space available for an engine in a monohull than in the cats slender shallow hulls making it more accessible and easier to work on. For the most part catamarans stay stable and you dont get the same feeling with. Downwind cats feel like a house gliding on the ocean at speed while monos roll from side to side.
Monohulls heel upwind and when the wind is on the beam while catamarans stay flat but pitch upwind. On average a cruising catamaran or trimaran is around 25-30 speedier than a conventional monohull of an identical size. In contrary monohulls might provide you with more of a real sailing feeling more thrills and exciting moments.
Monohulls are more maneuverable have lower costs and better when sailing upwind. On downwind runs reaches and broad reaches in particular catamarans usually beat monohulls when it comes to speed going about 20 faster than a monohull even outrunning bad weather when necessary. Due to their lighter weight multihulls tend to be faster and can sail better in lighter winds.
Catamarans usually have a lot more systems engines plumbing electrics etc than monohulls. Getting a mechanic to service two engines and sail drives will be more expensive than a comparable monohull with one engine. Load-carrying ability is a double-edged sword.
The only downside is that multihull vessels are only this fast if. They also offer safer anchorage and are easy to control. The experience on the water can change depending on whether you rent a catamaran or whether you rent a monohull.
Sailing Upwind - A monohull will point higher upwind and have better overall performance sailing upwind compared to an average catamaran. Catamarans have great maneuverability since most catamarans have twin engines they can be more comfortable to dock than a single engine monohull. Modern catamarans can do a 360 turn in their length.
