Based on different styles designs sizes and prices some of the best catamarans are Outremer 45 Catana 50 and Balance 526.
Catamaran with keel. Catamarans with dagger boards are able to point much better than catamarans with keels. If catamaran cruising is a passion you have been longing. The choice of having daggerboards is mostly a compromise between comfort and performance.
The most important catamaran design hull shape factor is the Prismatic Coefficient Cp. Boats with fixed keels are sometimes slower usually also heavier but also more comfortable as they have more living space. The best cruising catamarans with daggerboards or centerboards provide great cruising capability comfortable living ease of handling and strong construction.
The Lagoon 560 and the NYX 565 with hulls both designed in France declare a draft of 15 m 492 feet but they do not say how much is the boat draft and the respective fixed keel length height. LWL 128m 42ft BOA 73m. This also means more climbing and more scaffolding to work on the boat.
This is less the case on deep finely shaped performance catamaran keels. Catamarans sit on top of the water with much less keel area below the water and are much more affected by the wind. A monohull with a large keel lateral resistance makes less leeway than a catamaran with shallow keels.
You can feel it before you leave the marina how well they pivot around it. This is also why airplanes fly. Instinctively you might think that fine ends would be faster as they would cut through the water better.
The two hulls combined also often have a smaller. I think we all know and all agree that the best sailing boats are going to be the one with fin keels. But in fact you want a high Cp for high speeds.
