Request Pre-Charter InspectionAbout DIONEA
DIONEA is a 51.8-metre steel displacement yacht built in 1962 by Italian yard C.N. Felszegi and comprehensively refitted in 2020, carrying the Italian flag with interiors by Porfiristudio. At 307 gross tonnes she accommodates 12 guests across six cabins with a crew of nine. Her longevity is a testament to the quality of her original construction; a vessel that has been continuously maintained and substantially refitted across more than six decades occupies a distinct category from both modern production builds and from vessels whose age reflects neglect rather than stewardship.
DIONEA operates across the Western Mediterranean, with charter availability along the French Riviera, Amalfi Coast, Corsica, Sardinia, Monaco, and the broader Italian and French coastlines. This geography is well matched to a vessel whose displacement hull and cruise speed of 11 knots reward unhurried itinerary planning. She is suited to guests who appreciate the atmosphere and material honesty of a classically built steel yacht, and who value the character that comes from six decades of considered use. Those seeking contemporary amenity depth or a fast passage-making profile would look elsewhere.
The character of DIONEA has been shaped by the 2020 refit, which brought Porfiristudio's interior sensibility to bear on the vessel's existing spaces. The result is a yacht that wears its age with intention rather than apology — the steel hull and displacement form carry genuine authority in the anchorages of the Ligurian and Tyrrhenian coasts. Stabilizers both underway and at anchor ensure that her age does not translate into discomfort; she moves and rests with the assurance of a well-managed, mature platform.
The watersports programme is varied: two three-seat Sea-Doo jet skis, a windsurfer, two kayaks, wakeboard, water skis, a banana boat, doughnut, Sea-Doo sea scooter, and snorkelling equipment provide a full day's activity at anchor. Satellite TV, Wi-Fi, air conditioning, and audio connectivity address the interior living requirements of extended Western Mediterranean charter. DIONEA is a charter yacht for guests who understand that provenance and authenticity are as relevant as specification.
