• New Yanmar 4JH57 engine w/ upgraded saildrives
• Professionally engineered transom extension increasing LOA to over 52 feet.

This 2007 Lagoon 500 represents an exceptionally upgraded and thoughtfully engineered cruising catamaran, designed for serious offshore capability, diving operations, and extended off-grid living. Over the past several years the vessel has undergone extensive mechanical, electrical, and structural upgrades, transforming it into a highly capable platform for long-range cruising, charter operations, or private family adventures.

The boat features a massively upgraded electrical and energy system, centered around a 2,100Ah lithium battery bank (UL approved), approximately 2.5kW of solar generation, and three Victron inverter/chargers, allowing the vessel to comfortably run multiple air-conditioning units, refrigeration systems, and onboard equipment with minimal generator use. Combined with high-output engine charging and an 8kW Northern Lights generator, the system provides exceptional energy independence and redundancy rarely found on vessels in this class.

Mechanically, the vessel benefits from major recent servicing and drivetrain upgrades, including a 2026 Yanmar 4JH57 common-rail diesel with only ~50 hours, upgraded Yanmar SD-60 saildrives, and meticulous preventative service across the propulsion systems. The generator, rigging, air conditioning, and many onboard systems have also been renewed or upgraded, creating a boat that is both reliable and easy to maintain while underway.

A professionally engineered transom extension increases LOA to over 52 feet and dramatically improves the boat’s functionality. The enlarged sugar scoops provide safer dinghy access, improved water entry for diving, reduced pitching underway, and additional working space for fishing or watersports. Combined with a custom dive ladder and extensive scuba infrastructure—including an onboard compressor, tank storage, and organized gear systems—the vessel is uniquely suited for serious diving expeditions.

Additional highlights include a custom oversized flybridge bimini capable of shading seating for 10+ adults, extensive refrigeration and ice-making capacity for large groups, a flexible 5-cabin / 5-head layout, and numerous thoughtful upgrades throughout the interior and exterior spaces. The result is a rare offering: a fully outfitted, energy-independent Lagoon 500 that has been meticulously upgraded for comfort, safety, and real-world offshore cruising.
