Following the success of the Sirena Yachts range from 58 to 88 feet, a new hull study was undertaken specifically for the Sirena 118 using CFD analysis. At this length, the hull was developed to achieve efficient cruising in displacement mode while reducing fuel consumption.
The new geometry was shaped through a detailed study of volume distribution, LCG, prismatic coefficients and afterbody geometry, with the aim of reducing turbulence and eliminating the need for propeller tunnels.
Glass and carbon fibre construction, combined with resin infusion, helps reduce weight and maintenance requirements. The result is an elegant, strong and seaworthy motor yacht, balancing performance with a smooth and comfortable ride, and designed to travel the world in comfort and safety.
The Sirena 118 continues the brand’s timeless and distinctive design language. Strong yet understated, modern yet refined, her profile brings together familiar Sirena signatures including rectangular hull windows, the characteristic axe bow and aft-leaning fashion plates.
Outdoor living was central to the design. Folding aft balconies transform the stern into a generous area directly connected to the sea, while the owner benefits from a private forward outdoor space accessible directly from the suite.
Across the upper deck and sun deck, generous and flexible living areas accommodate different uses throughout the day. Rather than being conceived as separate exterior spaces, these areas form a connected living environment shaped around different levels of privacy, social interaction and a natural relationship with the sea.
The Sirena 118 introduces an interior language that is bolder, richer and more personal than previous Sirena models. Developed around the owner’s individual tastes, the interior brings together a wide spectrum of colours, materials and textures within a carefully considered design harmony.
Petrol blues, moss greens, burgundy, plum, mustard and cognac tones are combined with bronze and aged-metal finishes. Unconventional materials - including peacock feathers, seashell surfaces, antiqued mirrors, bespoke lacquers, textured fabrics and floral details - give each space its own character while remaining part of the same design story.
Many bespoke elements required extensive material research, sampling and development to balance aesthetic ambition with manufacturability, functionality and the technical requirements of life on board.
The result is an expressive yet liveable interior conceived entirely around its owner.
The Sirena 118 interior takes its cue from Sirena’s own spirit: “go further, go faster”, but also “home, sea, home”.
Built around exploration, the design draws inspiration from the people who went first, went deeper and went higher - and from the vessels and instruments that accompanied them. Riveted hulls, aircraft fuselages, vintage navy portholes and ship’s compasses are reinterpreted through contemporary forms and materials to create an interior that feels warm and lived-in rather than literal.
Throughout the yacht, this story unfolds through architectural surfaces, collected objects, bespoke furniture and unexpected materials. From the riveted bronze panels and floral glass of the main deck to the richly individual guest cabins and the owner’s two-level private space, every element contributes to a sense of curiosity and discovery.
It is an interior built for exploring, but designed to feel like home while doing so.
Strong yet understated. Modern yet refined.
The Sirena 118 continues the brand’s timeless and distinctive design language. Familiar Sirena signaturescome together in a balanced, sophisticated profile designed to retain its relevance and appeal over time.
Outdoor living becomes one connected environment.
From the main deck terrace and cockpit to the foredeck, upper deck and expansive sun deck, outdoorspaces flow naturally into one another. Folding aft balconies extend this experience even further, bringinglife on board closer to the water.
A private living environment created around the owner.
The owner’s suite extends across two levels, with a private study and lounge opening directly onto a balconyat sea level. More than a suite, it becomes an independent living environment with its own intimaterelationship with the sea.
An open space shaped around the way you live.
At the highest level, the sun deck has been conceived as an open and spacious living area offeringuninterrupted views. Its flexible configuration allows the space to adapt naturally to dining, relaxing,entertaining or navigating.
Curiosity, movement and the will to keep going.
The interior draws on the world of exploration — riveted hulls, aircraft fuselages, vintage navy portholesand ship’s compasses. Reworked through contemporary forms and materials, these references createspaces that feel adventurous yet warm and lived-in.
A richer, more expressive interior language.
Petrol blues, moss greens, burgundy, plum, mustard and cognac tones meet bronze, aged-metal finishesand richly textured materials. Bespoke pieces and unconventional surfaces bring different techniques andtraditions of craftsmanship together within one distinctive design language.
