About this Concept

The 143-foot (43.5m) SEA VOYAGER 143 is ready for production, promising extreme seaworthiness and luxurious comfort. Her concept allows owners and guests to live on board, becoming one with the sea.

SEA VOYAGER 143 boasts incredible internal volume with an exoskeleton superstructure that provides flexible layout options and lends itself for social use; as such, she is ideal for families, entertaining or chartering. The luxury sailing yacht’s main deck is divine showcasing spectacular views from expansive windows that surround. The lines between indoor and outdoor living on board are blurred.

As a new build, SEA VOYAGER 143 allows for versatility with its accommodations layout; it is able to accommodate 10 to 12 guests in five to six luxuriously appointed staterooms. Her on-deck master suite is a tranquil haven providing astounding views; it is complete with a dressing room and office. There also is a build option for the master suite to be built as two identical VIP staterooms. The luxury yacht’s additional four staterooms are found below deck. Each stateroom is complete with its own en-suite bath.

SEA VOYAGER 143’s hulls feature doors that open directly to the transom, right over the sea, allowing for unlimited recreational possibilities. The yacht also features a phenomenal beach area that allows for days to be spend lounging while relishing time on the water.


Mixed composite aluminum / fiberglass is used for the exterior skin under the water line for impact resistance, to allow cruising in high and low latitudes where ice is present. 
Above the water line, sandwich glass/carbon PVC, will be used for hulls, floors and bridges. 
Two main carbon beams connect the hulls. Secondary beams, take compressive load of masts.

Hull - Alumium (carbon option)
Deck - Glass (carbon option)
Mast - Alumium (carbon option)


The huge surface area of the hard top allows a solar collection network of 200m² capable of producing a significant amount of energy, complemented by photovoltaic glass windows which represent around 125m².


Carbon beams are a major element of the architecture of SV143’ creating an exo-skeleton.  They also have the function to drive a constant air flow across SV143’.


More than ever we are in a concept that wants to unite a man, a boat and the sea. “Sea-Voyager 143’  “, is our multihull  which open the gate to “Super  Yachts” category. Designed  to be  in  the linea  of transoceanic cruises, adapted to exceptional receptions or events. We have keep our goal to build  a large catamaran  able to sail with realistic performances  promising  a speed  of 15/18  nds, with the necessary comfort  to  a  super yacht  as is  the SV143’  that  can safely sail   whilst respecting the environment. To optimise the velocity of SV143, the confort of the boat under sail and  facilitate    beach  access,  we  have  made  the  choice  to  use  the  first generation of foilers


This is divided into two areas : One as a main living space, with part taken for the bridge and navigation station. The second  aft, an  independent  area  reserved  for “Owner’s cabin”  of  a feature  of all  Sea Voyager  yachts.  A  king size bed, a desk, a bathroom, dressing  room, made of this a luxurious space.  The option exists for 2 equal Master cabins each with full sea view.


Access to the bridge  is by a companionway  linking  the two decks. 
The twin Sea Voyager 143’  helm station allow 360 degree vision and ease maneuverability.  
Aft is the beach deck where discreet sunbathing is available up to eight lounger


4 further guest cabins, 2 twins cabins and 4 crews cabins, a professional  galley and enough storage for round-the-world autonomy.  Anchors are fixed and stored sit in the middle line of the main deck- Vertical transom doors give direct water access for  water sports and forward access to  the engine rooms and galley.- 2 shell doors on port side and starboard, allow tender storage.-Tank’s capacity of SV143’, whatever the latitude, permit to make the round  world, under sail or motor
