The largest Sirena yet
The 118 is the largest yacht Sirena has built in composite and the first true tri-deck in the range. At 36 metres overall on a 34 metre hull, she moves the brand out of big flybridge territory and into superyacht scale while staying in the material the Orhangazi yard knows best. GRP at this size is a considered choice, holding weight, maintenance burden and cost below what a comparable steel build would demand.
Volume is the headline. The yacht measures 265 gross tons under ITC 69, deliberately below the 300 GT threshold where regulation steps up sharply, so an owner gets close to maximum interior for a rulebook that stays manageable. Six guest cabins, seven heads and crew quarters for five are drawn into that envelope, and the tri-deck arrangement keeps the general layout flexible from hull to hull.
Frers, at displacement pace
German Frers, who has drawn every hull in the composite range since the first 64, gives the 118 a fast displacement form. Standard power is a pair of 1,550 hp MAN V12s, with 1,900 hp units on the options list. The yard quotes 15 knots as the natural cruise and 18 knots flat out, rising to 21 with the larger engines, numbers chosen for covering sea miles in comfort.
The philosophy matches the rest of the fleet. Long waterline, moderate power, low noise. Sirena's hybrid carbon fibre lamination appears again in the superstructure to keep weight aloft under control, and the yard's fixation on sound insulation carries into a hull intended to spend weeks at a time underway with its owner aboard, where the noise floor in the master cabin decides how a passage actually feels.
Superyacht volume, a private owner's balcony and a Frers hull, held just under 300 gross tons.
An owner's suite with its own balcony
The owner's stateroom is the 118's signature. It takes sea views on three sides and opens onto a private balcony with direct access to the sea, a feature normally reserved for yachts well above this size. The suite heads a layout of six cabins for twelve guests, which lets the boat work as a family flagship one month and a charter-capable platform the next.
Glazing is generous everywhere. The design team talks about enormous windows and carefully layered natural and artificial light, and the first interior images bear the claim out, with full-height glass on the main deck and long runs of hull glazing below. Cor D. Rover, who styles the interiors across Sirena's larger models, handles the fit-out, keeping the material palette calm and letting the light do the work.
Decks that unfold
Aft, folding deck wings extend the usable beam when the yacht is at rest, and a hydraulic platform launches and recovers the tender and water toys. These are systems from a class above, and they signal how the 118 expects to be used, anchored off a coastline with the sea deck open, the platform awash and the toys in the water while the yacht serves as basecamp.
Crew circulation is drawn tri-deck style, with three crew cabins for five and service routes that keep staff out of guest sightlines. Twelve guests, five crew and seven heads is an unusual density of accommodation for 36 metres, and it works only because the 265 gross tons are spent with discipline, an exercise the yard's engineering-heavy culture is well suited to.
From Monaco reveal to the water
Sirena unveiled the model at the 2024 Monaco Yacht Show and then kept an open build diary through 2025 and 2026, with BOAT International and SuperYacht Times both tracking the project as on schedule for a 2026 delivery. Hull one entered the water at the yard in July 2026, and the world premiere is set for the Cannes Yachting Festival in September 2026.
For the brand, the 118 does what the 88 did in 2019, stretching the ceiling and pulling the whole range upmarket behind it. For an owner, it offers tri-deck superyacht living from a yard whose value case against the established Italian and northern European names has been a running theme of press coverage at every size it has entered, with the Frers pedigree carried along intact.
Who it is for: An owner who wants tri-deck superyacht living and charter-grade accommodation without crossing the 300 GT regulatory line, from a yard still priced like a challenger.
