Few motor sailers reach 50 metres. Fewer still deliver the interior volume, the deck space and the wellness programme of a yacht twice the displacement. Aresteas is one of those exceptions, a 50.75-metre ketch launched by Turkish yard Yildizlar in 2017 and comprehensively refitted in 2026, drawing lines by Karatas Yacht Design and naval architecture by Furat Turan that give her both the sailing DNA and the wide-body comfort her size suggests.
The brief was specific: build a motor sailer that performs under canvas and lives like a superyacht at anchor. The result is a cold-moulded wood hull with a ketch rig, twin MTU 10V2000M72 engines for a 15-knot top speed, and a beam of 10.5 metres, generous enough to carry six en-suite cabins for twelve guests without the narrow-corridor compromises that mark many sailing yachts of this generation.
Step aboard and the scale registers immediately. Interiors by Ridade Tuncel and Aldo Viani balance warm timbers, natural light and restrained detailing across decks that feel open and uncluttered. A full-beam master on the main deck sets the tone: low furniture, wide windows, space that breathes. The remaining five staterooms share the same material vocabulary, teak, leather, linen, without repeating the same layout twice.
Where Aresteas separates from the fleet is in the spaces between the cabins. A glass-bottom jacuzzi on the upper deck offers colour-changing lighting and views straight through to the waterline, a conversation piece that doubles as a genuine wellness feature. Below, a dedicated sauna lined with Himalayan salt walls sits beside a cold-bucket shower and a private massage room, forming a spa sequence more commonly found on yachts north of 70 metres. A full gym, step machine, stationary bicycle, kettlebells, dumbbells, yoga mats, and a cinema room complete a programme designed for guests who charter for weeks, not weekends.
On the water, her toy inventory keeps pace. Twin jet skis, Seabobs, wakeboards, water skis, paddleboards and snorkelling gear deploy from the swim platform, while a 10-metre Pirelli PZero 1100 FB chase tender, seating up to ten, turns anchorage-hopping into an event of its own. The tender joined the fleet for the 2026 season and runs at speeds that make shoreside lunches and guided coastal hikes a natural extension of each day’s programme.
Ten crew operate behind the scenes. The chef specialises in Mediterranean cuisine, seasonal, local, adapted to each charter’s itinerary, and the service model is one of quiet competence rather than uniformed spectacle. The 2026 refit touched every system, so the mechanical side of the operation matches the cosmetic finish.
At 12 knots cruising, Aresteas covers the Eastern Mediterranean with ease. Greece, the Turkish Riviera and the wider Aegean are her natural range, with the engine-and-sail combination keeping fuel consumption, and engine noise, well below a comparable motor yacht. She is equally at home on the French Riviera and the wider Western Mediterranean.
At 130,000 euros per week she occupies a position that few sailing yachts of this size can match: genuine superyacht amenities, spa, cinema, gym, a chase tender larger than most owners’ day boats, wrapped in a sailing hull that moves quietly and draws attention for the right reasons.
