The Lagoon 52, the latest model developed by the world's leading builder of cruising catamarans, marks a whole new era in the design of such boats, as indeed did its predecessor, the famed Lagoon 500.
With its diamond-shaped vertical bows, beveled hulls, its as if levitated deck house and tall rig, the Lagoon 52 is no ordinary catamaran, but its originality goes a great deal further than just its "outer" appearance, or even its interior layout.
This new Lagoon is the result of lengthy discussions between the architects at Van Peteghem-Lauriot Prévost (VPLP), the Italian Nauta Design agency and the Lagoon design department. These discussions led us to make some important and sometimes radical choices, while remaining faithful to what we believe in, in terms of elegance, comfort, safety, user friendliness and, it goes without saying, performance under sail.

The infusion-moulding technique enables us not only to optimize the proportion of resin in the fibreglass (comparable to the pre-impregnated technique), but also to improve the bonding properties of the composite. The isolation of each balsa square by mechanical ties between the inner and outer skins improves the quality and reliability of the structure, and saves weight too. The systematic use of a very high-quality anti-osmotic resin ensures durability for all Lagoon catamarans.
Buoyancy is a guarantee of safety. All Lagoon catamarans comply with CE standards governing the unsinkability of multihull vessels. The fore and aft compartments of each hull are separated from the boat's living accommodation by watertight bulkheads. The density of the materials used and the absence of ballast increase buoyancy. Even after a collision your Lagoon will still be able to sail.
For successful cruising you have to be able to take along everything you need without overloading the boat. VPLP architects and the Lagoon design office pay special attention to this issue. An unladen Lagoon catamaran always floats well above its waterline and the hulls are designed to be just as efficient when the boat is fully laden with water and diesel, food, sailing gear and the personal belongings of the crew. Enjoy unparalleled performance and comfort.
Modern cruising catamarans thus generally carry a lot of equipment and this affects their displacement.
European pleasure boat manufacturing is regulated by CE rules that all boat builders have to observe.
Precise norms have been defined in terms of construction (structure) and safety (fire on board, flooding, etc…)
This regulation is also extremely precise concerning the way the specifications and technical characteristics should be presented to European consumers. Lagoon of course strictly follows CE norms in terms of construction, but also in terms of public information.
As an example, it is compulsory under CE norms to indicate a boat's displacement in a ready to sail condition, namely : fuel & water tanks 50% full, crew and crew equipment weight, safety equipment and sails weight etc.
As a consumer, you should make sure that all shipyards follow the rules of the game in this regard.
Although Lagoon always endeavor to reduce structural weight (infusion/sandwich techniques, etc.), significant hull displacement requires the use of fixed keels for several reasons:
Performance: A fin is not only longer and cuts through the water more cleanly, its volume also adds a significant amount of buoyancy to the design and this allows the architect to draw finer lines without affecting displacement.
Safety: The ability to hit a reef or run aground, whether voluntarily (beaching or careening) or accidentally, without sustaining hull damage is an undeniable safety factor. In the case of a Lagoon catamaran the keels are totally isolated from the hull so if one gets damaged, the yacht will not sink.
The symmetrical hulls of Lagoon catamarans cut cleanly through the water to ensure an identical flow rate on either side. Today, VPLP is the benchmark in hull design thanks to the experience gained from being the dominant force in multihull racing for more than 30 years. This experience constitutes a source of design innovation and guarantees quality and safety for the customer. Indeed, our architects are the best judges when it comes to achieving a happy compromise between performance and ease of handling.
Lagoon bridge decks are high above the water to guarantee comfort at sea with less slamming and less noise. Safety is also improved because less stress on the composite structure means greater strength. Another exclusive Lagoon innovation is the gull-wing bridge deck. First introduced in 2004 on the Lagoon 440, and further developed on all later models, the curved surface under the bridge deck reduces wave impact and noise to provide greater comfort.
The stresses on the rigging of a cruising catamaran are much greater than those experienced by a mono-hull vessel because it does not heel to port or starboard, thus the rigging and sails do not benefit from a "shock-absorbing" effect. That's why Lagoon calls upon the top specialists in the field (Z Spar, Spar-craft, Hall Spars…) to provide the most reliable and efficient equipment available. The spars, standing and running rigging and sails are all designed by our suppliers in consultation with our design office. Before entering production, Lagoon catamarans undergo sea trials to physically validate the calculated figures. These trials are carried out in the presence of technicians from our suppliers.
On-board energy supply:
Electrical circuits are one of the most vital aspects of a modern cruising vessel. Lagoon has made every effort to design electrical circuits that combine quality, reliability, ease of access and maintenance, lightness and safety.
Safety is a major consideration so the electrical systems on Lagoon catamarans are installed in strict compliance with CE standards, and even exceed them in certain respects. The quality of the cables, the way in which they are laid and ducted, their systematic coding, and the ease of access to distribution panels are all factors that Lagoon takes into account when fitting electrical systems to ensure the highest possible standard.
For health and safety reasons the conservation of foodstuffs is essential. Lagoon has therefore studied the question of on-board cold storage very carefully. No cruise would be enjoyable without an efficient refrigeration system. Lagoon and Groupe Bénéteau have much experience in this area and this has led them to implement an ideal compromise between a number of factors:
- best possible insulation, given the limited space available,
- lowest possible energy consumption,
- two-speed compressors, depending on the temperature of the compartment concerned,
- system efficiency,
- ease of maintenance,
- choice of widely available brands.
Generating and storing energy
Saving and storing energy on board a cruising sailboat is a classic problem. A pioneer in this field, Lagoon has always been heavily involved in the R&D work of the Group Bénéteau, particularly when the Lagoon 420 Hybrid was developed in 2008.
From the flexible solar panels located on Bimini awnings to the adjustable supports installed between the dinghy davits, Lagoon remains a leader where R&D in renewable energy is concerned.
Deck gear, rigging:
Experience acquired in racing has enabled Lagoon to choose nothing but the best deck gear and rigging: Harken, Lewmar, Z Spars, Sparcraft, Hall Spars, Incidences, etc.
The stresses on the rig of a catamaran are about ten times those of a mono-hull. This explains why we take so much care in selecting high quality equipment.
The deck plan design, choice of materials and calculation of stresses is a demanding job that is undertaken jointly by our architects, our suppliers and the Lagoon design office. Each item is subject to repeated and rigorous testing to ensure that we select the most reliable, efficient and durable equipment.
These tests are conducted in the marine-mist ageing chamber at the Group Bénéteau laboratory, as well as on racing boats at sea.
Lagoon catamarans are designed by internationally renowned architects Van Peteghem and Lauriot Prevost (VPLP), world leaders in multihulled yacht design.
