Beneteau Idylle 1550 Buyer's Guide
Shopping the brokerage market for a Beneteau Idylle 1550 means looking at a German Frers-designed, mid-1980s bluewater cruiser built by Beneteau and also marketed as the Idylle 51 and Moorings 51. She is the largest of the Idylle line, aimed at long-range cruising rather than racing, and the used fleet reflects that heritage in both layout and equipment.
Layouts on the Used Market
Owner three-cabin layouts are the more common on the used market, but both forward- and aft-master versions are available, and ex-charter examples are common. The aft-cockpit hull has no center-cockpit variant. Typical interiors pair a master cabin with ensuite, two additional double guest cabins, and on many boats a twin-berth crew cabin in the forepeak. The saloon carries a large U-shaped settee often to port, a straight settee opposite, and a proper navigation station; headroom is around 6 feet 6 inches.
Equipment and Common Upgrades
Buyers will find that watermakers and solar arrays are commonly fitted, reflecting the boat's passage-making intent, along with inverters and autopilots that support extended autonomous cruising. Chartplotters, EPIRBs, and life rafts are also commonly fitted for safety and navigation. The most consequential clusters for a buyer are power and energy — solar, inverter, and watermaker define how independently she can live at anchor — and safety systems, where a liferaft and EPIRB should be verified as serviced rather than assumed.
What to Inspect
The most documented concern is original deck core delamination from water intrusion, so tap-test the decks and check around fittings and winches original deck core delamination due to water intrusion. Original electrical systems are often outdated and warrant a survey of the panel and runs. Interior finishes may be tired, and the Perkins diesel, while reliable, could be reaching the end of its operational lifespan based on hours and care. Confirm hours and service history. Some owners have noted the boat can feel underpowered in light wind with the traditional rig unless modern sails are fitted.
Availability and Buyer's Takeaway
These yachts typically appear in Italy and the United States. For a buyer, the short checklist is: confirm deck-core condition, review the electrical system, verify engine history, and assess sail inventory for light-air performance. A sound example offers a spacious, solidly built cruiser with a protected cockpit and serious accommodation for long voyages.
