Lagoon 51 Information, Review, Specs

Sailing Performance & Handling

The sailing philosophy of the Lagoon 51 emphasizes ease of handling and stability over raw racing speed. Like many modern VPLP-designed catamarans, the mast is stepped further aft than in older generations, allowing for a high-aspect-ratio mainsail and a large, self-tacking jib. This configuration simplifies maneuvers for a short-handed crew, as the jib requires no winching during tacks. With a displacement of approximately 19,914 kg (43,903 lbs), the boat carries significant momentum. In a review by Sail Magazine, testers noted that while the boat is not a "light-air flyer," it maintains a steady, comfortable motion in a seaway, making it an excellent platform for blue water passages where predictability is more valued than agility.

The helm station is situated on the flybridge, providing 360-degree visibility, though the height of the boom—necessary to clear the flybridge seating—results in a high center of effort. This trade-off is common in flybridge cruisers, where the social benefits of the upper deck are prioritized. The yacht tracks well due to its fixed keels, though upwind angles are naturally wider than those of performance catamarans equipped with daggerboards.

Interior Comfort & Variations

The interior of the Lagoon 51 is a masterclass in volume maximization, offering several layouts to suit both private owners and high-end charter operations. The most common configurations include a 3-cabin "Owner" version, where the entire starboard hull is dedicated to a suite featuring a walk-in closet and a large head, or 4, 5, and even 6-cabin variants for the charter market. Each cabin typically features an island bed, a hallmark of the Nauta Design aesthetic that allows for easy access from both sides.

A standout feature is the salon's seamless connection to the forward cockpit via a large walkthrough door, a design element that facilitates airflow and communication between the two zones. The materials used reflect a shift toward sustainability, incorporating FSC-certified Alpi wood and recycled fabrics. Compared to its predecessor, the Lagoon 50, the 51 offers more headroom and larger panoramic windows that flood the living space with natural light. The low-profile transoms were specifically redesigned to provide easier access from the water or a dinghy, effectively extending the "beach club" feel of the aft cockpit.

Popular Mentions & Media

The Lagoon 51 received substantial industry acclaim upon its release, notably being nominated for and winning several "Boat of the Year" accolades. It was a featured highlight at the Cannes Yachting Festival, where it was praised for its innovative use of solar integration. The model has also been extensively documented by the sailing press for its role in Lagoon’s "Sea Drive" initiative, which explores more environmentally conscious manufacturing processes.

Known Issues & Buyer’s Checklist

While the Lagoon 51 is relatively new to the market, prospective buyers and current owners should monitor several technical areas common to large production multihulls:

• Solar Panel Maintenance: Because the 51 features integrated solar panels on the coachroof and flybridge, buyers should inspect the walk-on surfaces for any signs of delamination or micro-cracking, which can occur if the panels are subjected to excessive physical stress.
• Rigging Tension: Given the mast's aft position and the lack of a backstay, the rig relies heavily on the tension of the shrouds and the structural integrity of the chainplates. A professional survey should always include a check of the mast step for any signs of compression.
• Door and Window Seals: The forward walkthrough door is a highlight of the design but is a critical point for water ingress in heavy weather. Ensure the seals are supple and the locking mechanism provides a watertight fit.
• Electrical Management: With the increased reliance on solar and lithium-ion batteries in many 51 builds, the complexity of the Power Management System (PMS) is high. Buyers should verify that all firmware for the Victron or Mastervolt systems is up to date and that the charging cycles are balanced.

Community & Resources

Owners of the Lagoon 51 have access to a robust support network. The most prominent is the Club Lagoon, a manufacturer-sponsored platform that provides technical manuals, maintenance schedules, and a community forum for verified owners. Additionally, the Lagoon Owners Group is an active international community where sailors share specific modifications and cruising tips for the 51 model.

The Verdict

The Lagoon 51 is an uncompromising cruising platform designed for those who view their boat as a mobile home and a social hub rather than a racing machine. It excels in livability and environmental integration, making it one of the most forward-thinking models in the current catamaran market.

Pros:

• Exceptional social spaces, including the largest flybridge in its class.
• Innovative solar integration reduces reliance on fossil fuels.
• Multiple cabin configurations (3 to 6 cabins) provide extreme versatility.
• Easy short-handed sailing thanks to the self-tacking jib and flybridge helm.

Cons:

• High boom and high center of gravity can lead to more hobby-horsing in short chops.
• The large flybridge and high freeboard create significant windage when docking.
• Not optimized for light-wind performance without an optional Code 0 or Gennaker.
