The Beneteau Oceanis 510 is a well-regarded and capable bluewater yacht, and Necesse Est — a 1993 example — represents a particularly well-invested specimen of the model. At 14.97m (49ft 1in) she is a substantial yacht, well suited to extended Mediterranean passages and comfortable family cruising. Since 2009 her owner has committed to a thorough and sustained programme of maintenance and upgrades, with documented expenditure in excess of €140,000 across every major system aboard.
The most significant works include a full anti-osmosis treatment (2009), replacement of all standing rigging (2014), a new synthetic teak deck and cockpit (2020), Raymarine electronics throughout, a Tecnicomar watermaker, a stainless steel rollbar, retractable bow thruster, motorised in-mast furling mainsail, Code Zero with removable carbon bowsprit, and a complete battery replacement in 2025. She is French-flagged and currently lies at Cleopatra Marina, Preveza, Greece.

BROKER’S REMARKS
Necesse Est is a yacht with a clear and well-documented ownership story. Her current owner has taken a methodical approach to maintenance and improvement over more than fifteen years, investing heavily in the systems and structures that matter most: hull integrity, standing rigging, electronics, deck, and power management. The result is a yacht where the major capital expenditure has already been made, and where the next owner can step aboard with genuine confidence.
At nearly 15 metres, she offers a spacious and comfortable interior suited to extended passages with friends or family. The cockpit is sociable and well-equipped, with a folding table, quality cushions, a roll-up spray hood, and a purpose-built stainless steel rollbar carrying solar panels and tackles for the tender. The deck and cockpit were completely relaid in FLEXITEEK synthetic teak in 2020, giving the yacht a fresh and well-maintained appearance on deck.
Her sail wardrobe is extensive and capable — mainsail with motorised in-mast furling, furling genoa, storm jib on a Dyneema flying forestay, gennaker with funnel sock, and a Code Zero on a removable carbon bowsprit — making her an excellent platform for Mediterranean cruising in all conditions. The energy system is particularly well developed, with solar, wind, a watermaker, and a full set of new batteries, meaning extended time at anchor is entirely practical.
