The Beneteau Idylle 1150 is a thoughtfully designed cruising sailboat, introduced in the mid-1980s by the renowned French builder Beneteau. Measuring just over 37 feet in length overall, with a waterline length of nearly 29 feet, she was conceived to balance comfort and performance, appealing to sailors seeking a capable and livable vessel for extended coastal cruising or longer voyages. Designed by the accomplished naval architect Jean Berret, the Idylle 1150 carved out a reputation as a composed and dependable cruiser, known for its significant interior volume and seaworthiness.

InfoView listings

The Beneteau Idylle 1150 was in production from 1983 to 1988, emerging during a pivotal era for Beneteau as the company fully embraced fiberglass construction. This transition, spearheaded by Benjamin Bénéteau's grandsons André and François, allowed for more efficient production and the development of recreational sailboats that were accessible to a burgeoning leisure market. Beneteau itself described the Idylle series, including the 1150, as an alternative positioned "between cruiser-racer and motor sailer," offering sailors the "liberty" to pursue various sailing programs. Jean Berret, the naval architect behind the Idylle 1150, aimed to create a yacht that delivered a harmonious blend of sailing prowess and onboard comfort, aligning with Beneteau's broader philosophy of providing well-built, practical yachts. While specific variations like a MkI or MkII are not widely noted for this model, sail plans could vary, with options like full batten mainsails and roller furling genoas available.

Sailing Performance and Handling

The Beneteau Idylle 1150 is characterized by its composed and dependable sailing performance, designed more for comfortable cruising than high-speed racing. With a calculated Sail Area to Displacement ratio of approximately 17.60, she possesses sufficient sail power for decent performance in lighter winds without being overly sensitive in a breeze. Her high Ballast to Displacement ratio of around 48%, coupled with a fin keel and skeg-hung rudder, contributes significantly to her stiffness and stability, allowing her to stand up well to wind and provide a comfortable motion in a seaway. The Displacement to Length ratio of approximately 212.89 indicates a moderate displacement hull, suggesting a good balance between speed and load-carrying capability, positioning her as a capable performance cruiser rather than a heavy, traditional displacement vessel. Owners generally find the Idylle 1150 tracks well and maintains respectable speeds, reinforcing her design as a stable and comfortable boat for longer journeys.

Accommodations and Layout

A key attraction of the Beneteau Idylle 1150 is its generous interior volume and overall liveability, especially for a boat of its size. The layout typically features two or three cabins, providing ample sleeping arrangements. The spacious saloon is a central feature, often equipped with U-shaped seating to port that can convert into an additional double berth, complemented by a bench seat to starboard. Forward, a traditional V-berth offers a comfortable private cabin. A well-equipped galley, complete with a sink and storage, ensures practical meal preparation on board. A private aft cabin, typically located to port, provides additional berthing. Owners also appreciate the presence of a "salon library" and 120V outlets, enhancing the live-aboard experience. While specific details on finish quality and materials vary by individual boat and refit, Beneteau's general construction ethos during this period favored robust build quality and efficient production methods, contributing to their reputation for value.

Owner's Perspectives

Owners of the Beneteau Idylle 1150 consistently praise its sturdy construction and comfortable interior, highlighting its suitability as a seaworthy cruiser. Many find the boat's spaciousness to be a significant advantage, making it a comfortable platform for extended trips or even island hopping. The sailing characteristics are frequently described as enjoyable, with many reporting that she sails wonderfully. While generally well-regarded, prospective owners of any older Beneteau model, including the Idylle 1150, should be aware of potential common issues associated with boats of this vintage. These can include inspecting for signs of deck core rot, fiberglass cracking, or corrosion in older fittings. Additionally, some owners of other Idylle models have noted issues like a loose rudder post, suggesting this as a potential area for inspection. Overall, the Idylle 1150 remains a popular choice for those seeking a reliable, comfortable, and capable cruising sailboat.
