2018 Lagoon 450 F

This 2018 Lagoon 450F named “Altair” represents one of the most compelling value opportunities currently available in the Caribbean market.

Professionally maintained and proactively upgraded, Altair stands apart from comparable vessels by addressing the most common concerns associated with the Lagoon 450F platform—before they become issues. The result is a structurally reinforced, mechanically sound, and fully vetted vessel that offers true turnkey ownership.

Unlike many sister ships that require deferred maintenance or structural updates, Altair has undergone extensive improvements, including factory-certified bulkhead reinforcement, comprehensive system upgrades, and over 60 documented service items completed since 2024.

With major systems already addressed and additional scheduled service included in the sale, this vessel offers a rare combination of immediate usability and long-term confidence.

The current owner, a UK citizen, is preparing the transition to his next vessel and has priced Altair competitively to encourage a timely sale. Serious offer are welcomed and encouraged.

Structural Integrity 

Altair has undergone proactive factory-certified bulkhead reinforcement, completed in 2023.

This work was performed preventatively—not as a repair, meaning:

• No structural failure occurred
• Work was completed to Lagoon factory specifications
• Certification is on file

This eliminates one of the most well-known concerns with the 450F platform and provides long-term structural confidence for the next owner.

Why This Boat Stands Out

Most Lagoon 450Fs fall into two categories:

1. Deferred maintenance and hidden issues
2. Fully refit and priced significantly higher

Altair sits in a rare middle ground:

• Major structural and mechanical concerns already addressed
• Extensive documented maintenance history
• Turnkey readiness with scheduled service included
• Priced at a market-leading entry point
