Its place in the range

The 49M sits among Sunreef's power superyachts, a fully custom catamaran drawn for owners who want long-range capability with the stability of two hulls. It merges radical naval architecture with mature superyacht engineering. At 49 metres it is a true ship with the volume to match. It sits above the production power range as a bespoke commission. For an owner who wants to cross oceans without the roll of a monohull, the twin-hull platform is the draw.

The concept is built around a striking three-deck arrangement over a seventeen-metre beam. That width turns the yacht's length into exceptional deck and interior volume. Twin 3,400 hp engines drive it across oceans with range beyond 5,000 nautical miles. This is a catamaran conceived as a serious long-range motor yacht. The three decks stack owner, guest and social spaces so a large party can share the yacht without ever crowding it.

Design and deck life

The three decks give the 49M a commanding profile and a huge spread of social space. The seventeen-metre beam allows deck areas that a monohull of this length cannot approach. Owners lay out sun decks, dining, shade and a beach club to host on a grand scale. The exterior is shaped for entertaining and for life outdoors across the tropics. The upper decks give guests sweeping views while the beach club brings the party down to the water.

The styling carries Sunreef's muscular, modern signature into full superyacht proportions. Custom paint and detailing give the yacht its own presence. The tri-deck layout stacks private and social spaces for flow and privacy. The whole exterior is engineered for large parties and long voyages. Even at ship scale the design keeps the clean, purposeful lines that mark a Sunreef out on the water.

Interior and accommodation

Inside, the 49M offers the volume for a full superyacht layout with a commanding owner's deck and generous guest accommodation. The interior is finished to a bespoke brief in the owner's chosen materials. Large glazing keeps the principal spaces bright and open to the sea. The main deck flows out to the aft cockpit for indoor-outdoor living. The dedicated owner's deck gives a private retreat set well apart from the guest and social areas.

Systems, storage and tankage are scaled for genuine ocean passages with a full guest party and crew. The galley and crew quarters support professional service at superyacht level. Climate control and technical spaces are laid out for reliability far from port. The interior atmosphere is expansive and refined. The layout keeps owner, guest and crew movement separate, which is what makes long voyages comfortable for everyone aboard.

Engineering and performance

The 49M pairs its catamaran platform with twin 3,400 hp engines for a transoceanic range beyond 5,000 nautical miles. The wide hull spacing gives it stability and a comfortable motion in a seaway. The three-deck concept concentrates volume where owners want it. This is engineering aimed at crossing oceans in comfort. That range figure puts genuine transatlantic and transpacific passages within the yacht's reach.

Sunreef builds the composite structure in house for strength at controlled weight. The twin-hull form delivers efficiency and directional stability on long passages. Redundant systems support safe, self-sufficient voyaging. The result is a superyacht built to cover real distance. The redundancy in engines, tanks and systems is what gives an owner the confidence to head far from any port.

The owner it suits

The 49M suits an owner who wants a long-range motor superyacht with the stability and volume of a catamaran. It rewards those who cross oceans and host at grand scale. Buyers who value a bold, modern design and a serious range figure will find their yacht here. It carries a full crew for professional service. It fits the owner who wants to travel far and arrive rested, with none of the roll a monohull would bring.

It also stands as a distinctive flagship for an owner who wants to stand apart from monohull superyachts. The tri-deck volume and beach club give it real presence. For an owner ready for a crewed ship built to voyage, the 49M delivers. Life aboard is grand, stable and ocean-capable. The catamaran platform gives this owner a distinctive yacht that turns heads in any harbour it enters, far from the crowd of monohulls.

Who it is for: Owners who want a long-range crewed motor superyacht with the stability and volume that only a large catamaran delivers.
