Each cabin on both Monohull and Catamarans are double bed and sleeps 2 people max. If you decide to travel by yourself then you will have a cabin to yourself.
Catamaran cabins are bigger and more spacious due to the yacht being wider.
Monohull cabins are more narrow in comparison but still have plenty of space for 2 people. *On the Premium Monohulls and some Custom Yachts, there are bunk bed cabins sleeping 2 people.
There is also the saloon area that has a sofa bed where the table goes down and becomes a double bed - this sleeps 2 people comfortably.
