Sirena crosses into superyachts at 36m, stays under 300 GT
Sirena's biggest hull yet, kept under 300 GT
Sirena Yachts floated the first 118 at its Yalova yard in Turkey on 14 July, a 36-metre, 118-foot tri-deck that is the largest composite yacht the builder has produced. Naval architecture is by German Frers, the exterior styling comes from Sirena's in-house team, and the interior is by Dutch studio Cor D. Rover. She carries up to six guest staterooms and runs on twin MAN V-12 engines rated at 3,100 hp each for a 16-knot top speed, with an optional 3,800 hp package lifting that to 21 knots. The yacht makes her public debut at the Cannes Yachting Festival in September.
The number that reframes the boat is the tonnage. At 36 metres most yachts push past 500 GT, which triggers a heavier commercial code, more crew and a bigger survey and running bill. Sirena drew the 118 to stay under 300 GT, so an owner gets superyacht length on a footprint a smaller crew can run and a private owner can insure without stepping into full commercial territory. She is nine metres longer than the yard's previous flagship, the 88, and the volume gain is where the money goes.
A two-level owner's loft, and a repeat buyer already signed
The owner's accommodation is the headline layout. The main-deck suite connects by a private stair to a lower-deck room that Sirena's Ali Onger calls a 'loft', a space the client can fit out as an office or hobby area, opening onto a fold-down balcony at the water. The first hull was not built on spec: BOAT International reports she is already sold to a repeat Sirena client, and construction has moved through lower-deck joinery into systems, teak and paint.
A repeat owner stepping up to the yard's biggest boat is the quiet signal here. It says the production ladder is working, because a client who already owns a Sirena stayed inside the brand rather than defecting to a dedicated superyacht house at the 30-metre mark. For buyers watching from below, it also means the 118 arrives with a real owner's brief behind it rather than a show-boat spec, which tends to sharpen the layout choices on hulls two and three.
The 118 is one half of a two-track push up-market
The launch lands in Sirena's 20th-anniversary year and comes paired with a second, separate move. Alongside the composite range that now runs 48, 60, 68, 78, 88 and up to the 118, the yard has opened a steel-and-aluminium line starting with a 42.2-metre, 433 GT project. That larger boat uses a Van Oossanen fast-displacement hull, exterior lines by Luca Vallebona and an interior by Hot Lab, and is being offered for sale as it moves through paint.
The 118 and the 42 are two materials pointed the same way. Sirena is building a ladder that carries an owner from a production cruiser up to a 42-metre steel superyacht without leaving the brand, and the 118 is the rung where it crosses into territory usually held by larger, pricier yards. For a buyer, the draw is a semi-custom builder with a long series behind it now offering length and volume that used to mean starting from scratch with an unfamiliar shipyard. Cannes in September is where the market decides whether the jump convinces.
What owners and crew report
The owner's suite is built as a two-level private loft, not just a bigger cabin

What is good, and what to watch
Strong points
- Superyacht length without superyacht overheadHeld under 300 GT by design, the 118 gives an owner 36 metres of length while staying inside a survey and crewing bracket usually reserved for boats several metres shorter.
- A repeat buyer signed before the first hull even launchedBOAT International reports the first 118 already belongs to a returning Sirena client, evidence the yard's production ladder is retaining owners rather than losing them to bespoke builders at the 30-metre mark.
- A two-track route to bigger boats without leaving the brandSirena is running the 118 alongside a new steel-and-aluminium 42-metre line, letting an owner move from a production cruiser to a 42-metre superyacht without changing shipyards.
What to watch
- No independent sea trial or price exists yetEvery performance figure and the asking price both come from the yard; the boat has not yet had its public debut, due at Cannes in September, so there is no outside account to check them against.
- 16 knots standard is modest for a 36-metreThe base twin-MAN-V12 package tops out at 16 knots and cruises at 11 knots; the extra speed of the 21-knot version is a paid option, not standard equipment.
- The first hull's layout was built around one owner's briefA two-level owner's loft built for a specific, single repeat client can pull the standard inventory for hulls two and three toward that buyer's tastes rather than a blanker canvas.

| Speed and range | Standard twin MAN V-12s cruise at 11 knots and top out at 16 knots; the optional 3,800 hp package raises top speed to 21 knots (Sirena Yachts specification, Yachting Magazine). |
| Second hull | A second 118, hull 02, is already under construction for delivery in 2027 alongside the first hull (YachtBuyer). |

Questions this story answers
What happened?
Sirena Yachts floated its new 36-metre 118 flagship at Yalova on 14 July, the largest composite hull the Turkish production builder has ever launched and a clear step up from its 88. She arrives already sold to a repeat client, months before her Cannes premiere. For buyers the figure that counts is the tonnage: Sirena held the 118 under 300 GT, keeping crew, survey and running costs down at a length where most rivals cross into heavier commercial territory.
What is good about it?
Superyacht length without superyacht overhead. Held under 300 GT by design, the 118 gives an owner 36 metres of length while staying inside a survey and crewing bracket usually reserved for boats several metres shorter.
What should an owner or buyer watch?
No independent sea trial or price exists yet. Every performance figure and the asking price both come from the yard; the boat has not yet had its public debut, due at Cannes in September, so there is no outside account to check them against.
