Fans of sailing very often repeat their holiday with monohulls, until by chance or curiosity rented a catamaran and discover all the virtues and advantages, such as open spaces, stability on the water, reduced displacement and high potential for navigation. Each guest or couple can have their privacy due to the vast space on the yacht, a crew usually has  it's own cabins located away from the guest cabins. On the catamaran you will not ever suffer from sea sickness, it rarely can be tilted more than 5 degrees, so the guests can have breakfast, lunch or dinner quietly in navigation. In the moorings when the sea is rough you does not feel the movements of roll, so guests can have peaceful dreams. The catamaran can enter  in shallow bays due to the reduced immersion. When the wind is weak or pulls from aft catamaran goes much faster than sailboats . Disadvantages: costs more,  the moorings also cost almost double.
