Moorings 51 Information, Review, Specs

Sailing Performance & Handling

The Moorings 51 is a heavy-displacement cruiser that prioritizes stability and tracking over light-air agility. With a displacement-to-length (D/L) ratio typically in the moderate-to-heavy range, the boat excels in the consistent trade winds for which it was originally commissioned. Unlike modern light-displacement cruisers that may "skate" on the surface, the Berret-designed hull of the 51 slices through a chop, providing a comfortable motion that minimizes fatigue during long passages.

Under sail, the boat feels remarkably "stiff," a result of its substantial ballast and wide beam carried well aft. While the performance version (the First 51) featured a deeper keel and taller mast, the Moorings 51 utilized a more conservative sail plan to ensure it could be managed by a couple or a charter group without constant reefing. Handling is predictable, though the boat's mass requires careful planning during docking maneuvers, especially as the original configurations often lacked the bow thrusters that are standard on modern 50-footers. Historical commentary from long-term owners suggests that the boat reaches its hull speed easily in 15-20 knots of breeze, maintaining a steady helm that tracks well even when the seas build.

Interior Comfort & Variations

As a vessel designed to accommodate multiple couples in a charter setting, the interior of the Moorings 51 is characterized by a high cabin-to-length ratio. The most common configuration is the four-cabin, four-head layout, which was revolutionary for its time. Each cabin typically offers a private ensuite, a feature that transitioned the boat from a "sailor's vessel" to a "floating hotel" in the eyes of early 90s vacationers.

The salon is expansive, featuring the signature Beneteau "U-shaped" settee and a large dining table to port, with a linear galley or a secondary seating area to starboard depending on the specific production run. The use of rich mahogany or cherry veneers gives the interior a traditional, warm feel that contrasts with the minimalist, white-molded interiors of modern yachts. A sibling model, the Beneteau Idylle 15.50, shared the same hull but featured a more "owner-centric" interior with fewer cabins and a larger master suite, appealing to those who did not require the high-density sleeping arrangements of the Moorings version.

Popular Mentions & Media

The Moorings 51 holds a place of distinction in the history of The Moorings company, often cited in retrospective articles as the boat that helped define the "Crewed Yacht" experience in the British Virgin Islands during the late 20th century. While it has not been the primary subject of major motion pictures, it appears frequently in early yachting photography and promotional brochures that documented the birth of the modern charter industry. On digital platforms, several Moorings 51s have been documented by "refit" vloggers and blue-water cruisers who have chosen the platform for its robust construction and ability to be converted from a four-cabin charter layout into a spacious live-aboard.

Known Issues & Buyer’s Checklist

When inspecting a Moorings 51, potential buyers should focus on the technical realities of a boat that likely spent its first decade in a high-intensity charter environment.

• Structural Grid Bonding: Like many Beneteaus of this era, the 51 utilizes an internal fiberglass grid (liner) bonded to the hull. Inspectors should look for any signs of "tabbing" separation or cracking, particularly in the bilge areas and around the mast step, which can indicate past groundings or structural fatigue.
• Deck Core Moisture: The balsa-cored decks are susceptible to moisture ingress if deck hardware—such as stanchions, cleats, or the large hatches—was not properly re-bedded. High-signal areas for rot include the cockpit floor and the areas surrounding the chainplates.
• Engine Maintenance: Many units were originaly fitted with Perkins 4-236 or Westerbeke engines. While these are considered "bulletproof" by many mechanics, they are often high-hour units. Specific attention should be paid to the heat exchangers and the condition of the engine mounts.
• Keel Bolt Integrity: Given the age and the charter history, a pull-and-inspect or a thorough torque-check of the keel bolts is recommended to ensure no "smile" (gapping) is appearing at the leading edge of the keel-to-hull joint.
• Standing Rigging: Many of these boats were originally equipped with rod rigging rather than wire. Rod rigging has a finite fatigue life and can fail without the visible warning signs (like "fish-hooks") found in wire; if the rigging history is unknown, a full replacement is often necessary for offshore insurance.

Community & Resources

While there is no single "Moorings 51" owner association, the model is fully supported by the broader Beneteau owner community. Technical drawings and historical specifications are often accessible through the Beneteau Owners Association, which maintains an extensive database for older Berret designs. Technical discussions regarding the specific "Moorings" modifications are frequently found within the archives of The Moorings historical technical support or via dedicated Beneteau forums where owners share refit advice for the 51/15.50 hull series.

The Verdict

The Moorings 51 is a classic "heavyweight" that offers a level of seaworthiness and interior volume that is difficult to find in modern price-pointed cruisers.

Pros:

• Exceptional sea-kindliness and heavy-weather performance.
• High-quality Jean Berret hull design shared with racing pedigree.
• Robust 4-cabin, 4-head layout ideal for large families or groups.
• Substantial value for money on the used market compared to newer 50-footers.

Cons:

• Significant "sweat equity" likely required to update aging systems and charter-worn interiors.
• Large displacement makes the boat sluggish in light winds (under 10 knots).
• Maneuvering in tight marinas can be challenging without an aftermarket bow thruster.
