A Sail Tri-deck is a type of sailboat with three decks, the highest of which is primarily used for relaxing and entertaining. The design of the sailboat means that it usually has a main cabin that is located on the lowest of the decks and additional guest cabins located on the middle and upper decks. It also typically comes with a wide range of amenities, such as an onboard kitchen, washing and drying machines, and a dining room. With three decks, the sailboat has plenty of space to divide up activities, allowing passengers to maximise their time on board.
