Lagoon 450 Information, Review, Specs

Built by Lagoon Catamaran, a specialized division that originated from Jeanneau Technologies Avancées (JTA) in 1984, the 450 benefits from a heritage rooted in innovation and engineering excellence. Lagoon's consistent collaboration with VPLP Design, coupled with interior and exterior contributions from Nauta Design, ensures a harmonious blend of aesthetics and hydrodynamic efficiency.

History and Design

The Lagoon 450 entered production in 2014, evolving from the established success of previous Lagoon models like the 440, which notably introduced the concept of a flybridge to cruising catamarans of its size. VPLP Design, in partnership with Lagoon and Nauta Design, took on the challenge of creating the 450, aiming for a larger vessel with increased sail area and enhanced comfort. This model became one of Lagoon's best-selling catamarans, with over 800 units produced.

The design philosophy behind the Lagoon 450, as with many Lagoon models, focuses on maximizing living space and creating a seamless flow between interior and exterior areas, all while maintaining seaworthiness and ease of handling. A significant design variation introduced with the 450 was the option between the "F" (Flybridge) version and the "S" (SporTop) version. The 450F features a raised flybridge helm station, offering excellent visibility and a dedicated area for sailing operations. In contrast, the 450S (Sportop) positions the helm at deck level, aiming for a lower profile and easier access to the cockpit, enhancing the sense of connection with the water and simplifying handling with a smaller crew.

Sailing Performance and Handling

The Lagoon 450 is a cruising catamaran designed for comfortable voyages rather than outright racing performance. With a reported total sail area of 1398 square feet (with the standard full-batten mainsail), she is capable of respectable speeds for her class. Owners typically report average speeds of 7-8 knots, making her efficient for passage making. While catamarans generally do not point as high into the wind as monohulls, the Lagoon 450 is noted to sail at approximately 45 degrees apparent wind angle, equating to a course over ground of around 55 degrees, which is reasonable for a cruising multihull.

Her wide beam of 25.82 feet contributes significantly to her inherent stability, a hallmark of catamaran design, providing a comfortable and level platform even in choppy seas. The twin rudders enhance maneuverability, and the dual Yanmar 90 HP engines provide ample power for motoring and close-quarters handling, an essential feature for a vessel of this size. Overall, the 450 is known for being relatively easy to handle, even for a small crew, particularly the Sportop version with its deck-level helm.

Accommodations and Layout

The Lagoon 450 is celebrated for its generous accommodations, leveraging its wide beam to offer spacious interior and exterior living areas. The layout is typically available in two main configurations: a 3-cabin owner's version or a 4-cabin charter version.

In the popular 3-cabin owner's version, one hull is often dedicated to a luxurious owner's suite, typically featuring a large double berth, ample storage, and a private head with a separate shower. The other hull houses two guest cabins, each with its own en-suite bathroom. The 4-cabin layout provides four independent cabins, each with an en-suite head, making it highly suitable for charter operations or larger groups.

The main saloon is a significant feature, characterized by Lagoon's distinctive rounded corners and large vertical windows that provide panoramic views and abundant natural light. This open-plan space seamlessly connects to the expansive aft cockpit, creating a large, integrated entertaining area. The galley is typically well-appointed, often located within the saloon, and designed for functionality at sea. Storage throughout the vessel is generally plentiful, accommodating the needs of long-term cruisers. While specific details on ventilation systems may vary by individual boat and optional upgrades, the large windows and deck hatches facilitate airflow.

Owner's Perspectives

Owners of the Lagoon 450 frequently praise its comfort, stability, and the sheer volume it offers for liveaboard cruising. Many appreciate its ease of handling for a boat of its size and its capacity for long-distance voyages. The dual helm options (Flybridge vs. SporTop) are often a point of discussion, with owners choosing based on their preferred sailing style and visibility requirements.

However, a well-documented concern among some Lagoon 450 owners relates to potential issues with bulkheads, particularly in earlier models. While Lagoon states that quality and safety are central to their design and manufacturing, and they provide support for owners, this issue has been a recurring topic in owner forums and discussions. Prospective buyers of a Lagoon 450 are often advised to investigate whether any necessary bulkhead reinforcement kits or repairs have been carried out. Despite this, many owners express overall satisfaction with their Lagoon 450, highlighting its liveability and solid construction.
