Remarks :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.

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.

Accommodation :Necesse Est offers a generous interior typical of the Oceanis 510, with ample headroom throughout and natural light from the deck hatches and saloon windows. The saloon lends itself equally to coastal cruising and extended passages, with a practical galley and a well-appointed navigation area. The forward crew cabin has been converted by the current owner into a dedicated sail locker and equipment store, making the remaining cabins and heads all the more spacious and comfortable for a cruising couple or family. LAYOUT The yacht features a central saloon with settee and dining area, a forward accommodation area, and twin aft sleeping cabins offering good privacy. Two separate heads compartments are fitted, each with electric toilets. The forward cabin has been repurposed as a sail locker, walk-in equipment store, and spare parts stowage — a practical modification for serious cruising.
