The heart of the catamaran is the saloon. This is a very bright area, surrounded by large windows, capable of accommodating a dining area for crews of 8 to 10 people, a well-stocked galley, and the chart table with a full instrument panel. It can be up to more than twice the size of a dinette of a monohull of the same length. In case of bad weather, you don't have to take refuge in the cabins below deck, but can sit comfortably on the dinette sofa without giving up the view around you.

On the same plane as the saloon is normally organized the cockpit, a large area equipped with seating, sofas and a dining table. The cockpit outside and the dinette inside are connected by a hinged or sliding door. The cockpit is usually protected by a structural bimini that provides shelter from sun, rain and wind.

It is usually located at the entrance to the square, like a peninsula separating the indoor and outdoor space. The kitchen is equipped with all amenities. You will find a cooktop and refrigerator like those in the house. You will also have ample space to stow galley, dishes and equipment. Thanks to its location "out of the water" you.

The sleeping area is divided into the two hulls and reached by steps from the saloon. The cabins are of an extraordinary size and height, nothing to envy the bedrooms of homes or hotels. Typically, a 40-foot catamaran has four double cabins and two bathrooms; a 44-foot catamaran may have four double cabins each with private bathrooms and two sailor cabins (singles) in the bow. The cabins in most cases have double beds and have rectangular windows, which are larger than portholes.

This is the large space located in the bow. Where you can walk around, lie down to sunbathe or use it as a springboard for diving into the sea. Sometimes the net is replaced by a rigid structure that will still allow you to lie down and enjoy sailing.

In most cruising catamarans, the helmsman's station is located in an elevated position above the cockpit. This has the great advantage of having the entire guest area completely clear of maneuvers and, at the same time, allowing the skipper to maneuver without having any kind of obstruction. It also ensures a 360-degree view for the skipper, which is especially useful during mooring phases.
