Golden Yachts unveiled O’Ceanis in October 2025 — an 85-metre motor yacht already in build at the group’s own facilities at Perama, on the western edge of Piraeus, and set to launch in 2027. She is steel and aluminium, 13.2 metres in the beam and drawing 3.45, with her exterior, her guest suites and her bridge drawn by Studio Vafiadis and her interiors by Massari Design of Fano. The line that matters, though, is not a dimension. Her propulsion is diesel-electric — 19.5 knots at maximum, 16 at cruise, and silent running for 4 hours by day or 8 by night.
Aboard, on paper
The owner’s suite takes a private balcony of its own. Beyond it lie two VIP suites and double and twin guest cabins. A swimming pool sits on the main deck, a lift serves every level, and the bow carries a fully certified helipad. The upper deck holds a bar carved from rock; the sundeck, a wellness centre with a massage room and a gym. At the waterline the beach club opens onto a swim platform with a firepit and a hammock, and the garage is sized for a 9.8-metre limousine tender and an electric Frauscher x Porsche 850 Fantom Air.
Massari Design’s drawings keep a dark and deliberate register — marble floors, modern art hung with intent, and a curving staircase clad in dark wood that is plainly meant to carry the eye rather than the traffic. It is the vocabulary the Fano studio brought to the yard’s 60-metre O’Madeleine, delivered in 2025, held at a larger scale.
The case for silence
Diesel-electric is the news beneath the specification sheet. Generators make the power and motors turn the shafts, which frees the engines from the rhythm of the propellers and takes the vibration out of the hull. The stated consequences are lower carbon dioxide emissions and those silent modes: 4 hours in daylight, 8 through the night.
Eight hours is not a technical curiosity. It is a whole night at anchor in a Cycladic bay without the hum that usually stands between a guest and the water — the sound so constant on a yacht of this size that most owners stop hearing it and only notice its absence. For a vessel intended for Greek waters, where the pleasure of the thing is very often stillness, that is the specification with the most to say.
The arc of the yard
O’Ceanis is not the largest hull Perama has floated. That remains the 95-metre O’Pari of 2020, and below her the 88-metre Project X of 2022 and the 85-metre O’Ptasia of 2018 — a fleet that also carries the 77.7-metre O’Rea from 2023 and the 60-metre O’Madeleine from 2025. What the new hull marks is not a record but a consolidation: a Greek yard building at the top of the market often enough that the length has stopped being the story.
Studio Vafiadis has drawn three of those vessels for Golden Yachts before this one — O’Ptasia, O’Pari and O’Madeleine — which is the kind of continuity that separates a yard with a house style from one taking commissions as they come. A yacht is a long conversation between a builder and a designer, and the fourth is easier than the first.
What she signals
Greece has been a shipping country for as long as it has had a coast, without that authority translating cleanly into the building of yachts at the very top of the market. That correction has been under way at Perama for some years, quietly, out of sight of anyone who comes to Athens for the city. It is a working shore of slipways and cranes on the far side of the port, and it has grown into work of this order rather than announcing it.
In 2027 a yacht of this order will come off a slipway a half-hour from the centre of Athens rather than out of a shed in northern Europe, and she will lie at anchor without a sound. For the client who takes the Cyclades from the water, both halves of that sentence are worth something.
The house makes the introduction, for those who ask.
