Catamarans have shallow drafts.
Sailing monohull vs. catamaran. The magnificent HH66 catamaran image thanks Sail Magazine. He pointed out that catamaran buyers have voted for accommodation which means weight over performance so the dilemma of. The difference in living accommodation between say a Lagoon 410 and a Bavaria 46 cant be overstated.
Monohulls are more maneuverable have lower costs and better when sailing upwind. Due to their lower waterline surface area catamarans are certainly faster. A catamaran is much better than a monohull in many ways.
In 2011 I was involved in a test of three cruising catamarans and among my fellow judges was multihull design legend Nigel Irens. The average cruising catamaran is big like really big compared to the average cruising monohull. Having said that overall monohulls point higher and have better performance upwind.
Another can be even ones purpose-built for cruising. A 44 Catamaran has about the space of a 53 monohull. This is probably because catamarans are easier to sail than monohulls and they can also be safer if you are just getting started as a sailor.
Deciding between a catamaran and a monohull is a big decision and one worth considering well before taking the plunge. Monohulls heel upwind and when the wind is on the beam while catamarans stay flat but pitch upwind. Not only is each space galley cockpit cabin and heads bigger but there are more of them.
Catamarans are in most of the sailing conditions faster than monohulls because of their hulls which are less immersed in the water and have a smaller area in the water to create drag. Do you want one hull or two. This means catamarans can get into places monohulls yachts often cannot reach and that they can also anchor closer to shore.
