Lagoon 400 S2 (2017) – 4 cabins / 4 bathrooms

Lagoon 400 S2 from 2017, this well-maintained 4-cabin, 4-bathroom catamaran is a highly capable and extensively upgraded cruising yacht, designed for comfort, performance, and true autonomy at sea. Combining recent high-value equipment—including lithium batteries, large solar capacity, new sails, and modern electronics—with practical liveaboard features and thoughtful custom storage, this vessel is ideally suited for long-distance sailing or full-time cruising in complete independence.

Autonomy & energy systems
This Lagoon 400 S2 is exceptionally well-equipped for extended cruising, with a strong focus on autonomy. A large 2500W solar array combined with a 900Ah lithium house battery bank (2024) ensures substantial energy independence, supported by a 2500W inverter and a Honda 2.2kW generator for backup. Water production is handled by a Rainman watermaker (70L/h) with new membranes (2025), making the vessel fully self-sufficient for long stays off-grid.

Electronics & communication
The boat features a complete and modern B&G electronics suite, including radar and AIS, complemented by two chartplotters (helm station and chart table, 2023) for safe and efficient navigation. Connectivity is enhanced with Starlink, offering reliable high-speed internet even at sea—ideal for remote work or extended cruising.

Sails & deck layout
Equipped with recent Elvström sails (mainsail and headsails, 2023), the sail plan is both efficient and performance-oriented. A Rolly Tasker gennaker on an endless furler adds versatility downwind. Handling is simplified with an electric winch for the mainsail. The semi-flybridge helm station, protected by a full bimini, provides excellent visibility and comfort while maintaining easy access to all sail controls.

Dinghy & anchoring
The anchoring setup is robust and reliable, featuring a Rocna 25kg anchor (2023) with 70m of chain. The tender package includes a 3D Tender 2.70m in Hypalon with covers, paired with a Yamaha 15HP outboard—ideal for shore access and exploration.

Interior & comfort
The interior is well thought out for liveaboard comfort, with multiple custom storage solutions throughout the boat, maximizing usable space. The galley is fully equipped with a 130L refrigerator, a 100L freezer plus an additional Dometic 100L unit, and a versatile cooking setup including a 4-burner gas stove and an induction plate. Electric toilets with holding tanks add to onboard convenience.

Engines & mechanical
Powered by upgraded 45HP engines with 3-blade propellers, the boat offers improved performance under power. The engines have been regularly serviced, ensuring reliability and peace of mind.
