Sun Odyssey 51 (Jeanneau) Information, Review, Specs

The Jeanneau Sun Odyssey 51 was introduced in 1989 and remained in production until 1992. During this period, Jeanneau, under various corporate shifts, maintained its core manufacturing ethos of embracing new technologies and prioritizing quality in fiberglass construction, a hallmark established with their earlier successful models like the Sangria. The design of the Sun Odyssey 51 was a collaborative effort, with J&J Design responsible for the overall concept, deck, and interior arrangement, while the prestigious office of Bruce Farr, known for designing fast racing yachts, handled the hull design. The interior aesthetics were further refined by Andrew Winch, who harmonized colors and materials to enhance the boat's character.

The design philosophy behind the Sun Odyssey 51 was to create an ultimate holiday sailing cruiser, emphasizing an entirely open, simple, and uncluttered deck layout with ropes led aft for ease of handling. Although many units were built for the charter trade, owner versions were also available, often featuring a 7-berth layout [7, 9,. This model was also known by the designation STARDUST 525 during its production and later evolved into the Sun Odyssey 52.2 [8,.

Sailing Performance and Handling

The Sun Odyssey 51 is recognized for its impressive sailing performance and easy handling characteristics, a testament to its thoughtful design. With a displacement of 30,860 lbs and a waterline length of 42.33 feet, it boasts a Displacement to Length (D/L) ratio of approximately 181. This indicates a relatively light displacement for its size, suggesting a more agile and potentially swifter cruising yacht compared to heavier, more traditional designs.

Its Sail Area to Displacement (SA/D) ratio of around 17.33 is respectable for a cruising vessel of this magnitude. This ratio suggests that the Sun Odyssey 51 is well-powered to perform capably across a range of wind conditions, including lighter air, without being excessively tender in stronger breezes. The boat's ballast-to-displacement ratio stands at approximately 0.32, which is moderate. However, this is complemented by a substantial 16-foot beam and a wing keel, both contributing significantly to initial stability and lift. Owners frequently praise the boat's comfortable motion through chop, and its balanced helm under sail, even in brisk conditions, contributing to its reputation as a very capable long-distance cruiser. The clean, unobstructed deck layout, with all lines led aft, further simplifies sail handling, making it manageable for a cruising couple or family.

Accommodations and Layout

The interior of the Jeanneau Sun Odyssey 51 was designed with comfort and livability in mind, consistent with Jeanneau's broader philosophy of creating "liveable boats" with clever layouts and comfortable amenities. While specific headroom figures are not consistently available, the boat was intended to serve as a genuine "second home on the water".

Interior layouts typically included multiple cabins, reflecting its suitability for charter operations or larger families. Versions with five cabins have been noted, likely for charter purposes, alongside more common owner versions offering up to seven berths. The design prioritized spaciousness and functionality, with Andrew Winch's influence visible in the harmonious blend of colors and materials. Common arrangements would feature forward V-berths, a main salon, a well-equipped galley, and aft cabins, offering privacy and comfort for multiple occupants. The emphasis was on durable finishes and practical storage solutions, providing the amenities necessary for extended cruising.

Owner's Perspectives

Owners of the Jeanneau Sun Odyssey 51 generally commend its robust construction and its ability to deliver a comfortable ride, particularly in varied sea states. Its ease of handling, especially given its generous dimensions, is a frequently lauded characteristic, making it a viable option for both experienced cruisers and those looking to move into a larger vessel. The boat's design as a "very capable long-distance cruiser" is often highlighted, underscoring its suitability for extended voyages.

However, like any yacht of its age, potential buyers and current owners should be aware of common maintenance considerations. A "rusty keel" can be a localized issue, typically stemming from maintenance neglect rather than a design flaw. There have also been anecdotal mentions of concerns regarding loose stringers and creaky floors in some older models, suggesting that a thorough survey is advisable to identify any structural issues that may have developed over time. Given that many Sun Odyssey 51s were originally built for the charter market, their operational history should be carefully reviewed, as heavier use can impact the condition of various systems and components. Independent owner forums often serve as a valuable resource for sharing insights on maintenance, potential upgrades, and addressing common wear-and-tear items.
