Uninterrupted ocean views
Travelling with a Long Island Power is a whole new experience, with amazing sea sight wherever you are on board.Beyond an uninterrupted ocean view, the catamaran features a natural stability, equally navigating and mooring, allowing to live on board in comfort and serenity. The deck surface adds a lot of living spaces. The Long Island Power 78’ main deck offers a lounge area and a sea water bath, providing a safer alternative to sea bathing. This relaxing space is directly connected to the saloon, creating a continuity and blurring the lines between interior and exterior. This combination brings a breathable and smooth circulation on board, multiple spaces can be enjoyed in various ways, creating a peaceful retreat or a welcoming spot for a family or friends gathering.
The main aft deck is divided between a lounge, a dining area with a table for 8 persons and sunpads on both sides. A long seat separates the main aft deck from the hydraulic platform. It can be fully protected from disturbed weather, creating an additional indoor space.
The hydraulic-platform can support up to a 15’ tender, and offers the possibility to create an added access to the sea and in the most lowered position, can become a beach to sunbathe and jump in the water. The aft starboard transom is equipped with a hydraulic passerelle to reach land when being at quayside. The shallow draft enables to reach breath-taking anchorages.
Boundless possibilities
The voluminous indoor spaces are flooded with natural light and immediately makes you feel at home. The warm and rich selected woods (oak and walnut) complement the welcoming and serene atmosphere. With 132 square meters of living area, this boat has a lot to offer. The main space is comprised of a galley, main saloon, dining area and a desk. A large central island made of granite separates the spaces.
Aboard 4Ever, the association of the interior layouts entirely designed and made to measure by JFA Yachts and the presence of furnitures from renown brands (Valdenassi, Tribu, Moroso, Poltrona Frau, Cassina, Berto Salotti) make this first Long Island Power particularly personal and endearing.
