The 2020 Lagoon 46 catamaran is built on a fiberglass hull with a beam of 26 feet, offering the spacious accommodation and practical layout that defines this successful cruising design. Twin Yammer diesel engines of 114 horsepower each drive her through the water via saildrives, delivering a cruising speed of 7.5 knots with a maximum speed of 9 knots. The yacht retains excellent sailing characteristics alongside her reliable power capabilities.
Accommodation consists of six cabins and four heads, arranged in a configuration with four main cabins plus crew quarters forward in both hulls. The flybridge helm provides commanding visibility and control, while the deck layout prioritizes both safety and practicality for extended voyaging. The cockpit and cabin spaces reflect Lagoon's design philosophy of combining comfort with functionality for long-term cruising and liveaboard use.
Systems supporting self-sufficient operation include a 1,200 amp-hour lithium battery bank installed in 2026, paired with a 1,200-watt solar array added in 2025 and managed through a Victron energy system. A Rainman watermaker, 72,000 BTU Dometic air conditioning, 11-kilowatt Onan generator, and Starlink internet connectivity provide independence from shore facilities. The saildrive seals were replaced in April 2025, and standing rigging was professionally inspected in 2026. The yacht benefits from factory-reinforced structural bulkheads specified during construction and carries no history of grounding or structural damage.
Equipment inventory is extensive and includes a 2020 Highfield 340 centre-console tender with a 2025 Mercury 20-horsepower outboard. Additional gear encompasses diving equipment, fishing tackle, kitesurfing and paddleboard equipment, an underwater scooter, spare anchors, comprehensive Yammer engine spares, watermaker spares packages, saildrive seal kits, and two spare propellers. Regular engine and generator servicing has been maintained throughout ownership.
