I already wrote a post about the 150 by SUNREEF. The design department of Sunreef Yachts has pushed the concept as far as possible and came out with stunning 3d of the interior and exterior of this amazing mega catamaran. In the following text, Sunreef Yachts details the concept behind the design. Enjoy…


For immediate release,

15 May 2009 – Gdańsk, Poland


ONE FIFTY by Sunreef is the result of a year-long study into a new, revolutionary concept for modern and luxury catamaran – the megayacht, as an alternative, both aesthetically and functionally, for all current catamarans on the yachting market. This unique design technique insisting on pure simplicity and minimalism of form has been successfully adopted by the car industry and is now becoming increasingly popular in yachting. ONE FIFTY by Sunreef is the biggest sailing catamaran in the world. However, still in the design stage, this megayacht is waiting for her future owner.

The key words for this extravagant design are: uncut teak, sleek shell (hulls) and streamlined core (deckhouse).

The futuristic look of ONE FIFTY by Sunreef comes from one big innovation, namely almost invisible full-beam deckhouse. The link between the aft deck and the navigation station on the top is through a centrally positioned sloping deck. We are not talking here about a typical deckhouse shape, as the hulls, sides, bulwark and the superstructure itself are not traditionally shaped but rather combine together into one huge solid. The deckhouse spanning the entire beam provides the significant advantage of creating another level (floor) within the hulls. Thanks to this, the possibilities for arranging space increase remarkably. The main deck has gained impressive living space; all cabins for 12 guests are on this level and are generously illuminated by a big glass top. Below decks are located crew quarters for 9, all storage rooms and the galley.


A closer look at the whole yacht allows us to see two clearly contrasting structural elements, placed one inside the other. The external layer is a wide clear metallic shell with a black, monolithic core inside. The teak is applied continuously along the hull line, which enhances the sleek shape of the boat. The shell is the most streamlined part of the boat and logically forms hydrodynamic hulls. On the sides, there are two pure, aesthetic lines comprising a set of windows. The core looks like a huge glass construction yet it is not made of glass but simply imitates it. Solar panels can be fitted to provide lots of natural, green energy to the yacht.

As for the deckhouse, the ONE FIFTY by Sunreef does not have a classic deckhouse clearly dominating the bulwark level. This tendency to simplify the profile line can be observed frequently on monohull superyachts. The deckhouse lowers towards the bow section and finally reaches main deck and hulls level. This gives the yacht’s profile an expressive look and has an aggressive exterior shape. Pure lines and a minimalist shape can be eqasily disturbed by installing traditional guard rails on board; therefore ONE FIFTY by Sunreefhas a profil sleak and clean, free of railings and exploits instead differences in deck levels as a natural protection.

The exterior teak surfaces are the only ones accessible to guests and the glass/ sololar panels tops above them can be reached by crew only for maintenance purposes and mooring.

Another innovative technical feature on board is the boom which doubles as a crane for the lifeboat or for a large tender to be stowed out of sight, aft of the engine room.

The teak covering aft section creates an impression of fluidity and seems to fall down from the navigation station throughout the main deck level towards the end of the hull


The interior design is based on the specific aesthetic tendency in space organisation; therefore, it is not a final solution, rather a suggestion. The steel frame supporting glass top is created by symmetric squares and combines very well with the space division of the salon and cabins thereby giving the impression of linear fluidity.

Thanks to high level of luminosity and the glass walls of the salon and alley, the border between indoor and outdoor space is very soft. Guests will be able to enjoy panoramic views looking at the aft or admire flapping sails above their heads. Shade can be created by pulling down blinds between ceiling panels.

The sloping deck with glass walls hides below a small garden and mattress and thus create a intimate meditation area which can be converted into a comfortable cinema spot with a huge screen in the shady zone where the sloping deck becomes a fly-bridge.

To enable the crew to operate the yacht efficiently, access throughout the ONE FIFTY for crew and guests has been carefully separated for both parties. Access for guests is aft via large glass doors while the crew enter directly from the hull by a passerelle.
