2010 Lagoon 400 Owner's Version NEW ENGINES

This 2010 Lagoon 400 Owner's Version is a 40-foot fiberglass catamaran built for serious cruising. She features twin Yanmar diesel engines that were completely replaced in 2025, along with new panels and wiring. A professional hull refinishing and bottom paint refresh completed that major repower, bringing her systems up to current standards. The mast was shortened to 63 feet in 2020 under professional supervision to suit Intracoastal Waterway passage, and she carries upgraded SD60 sail drives installed in 2022 alongside entirely new standing rigging.

The owner's layout prioritizes privacy and comfort, with a generous owner's suite that includes an office area and large ensuite bathroom with stall shower. The guest cabin on the port side offers two queen berths and a separate head. The boat carries substantial self-sufficiency systems: a 40 GPH water maker installed in 2022, a Battle Born lithium battery bank of 810 amp hours with ten-year warranty, and ample solar power. Navigation and deck gear include a Raymarine ES123 system, Quick 1000W windlass, electric Harken winches, and a full complement of running rigging updated in 2022.

Recent work spans multiple systems. The 2024 season brought new overhead hatches, a new Mabru air conditioning unit, and re-plumbed heads with a new filter system. A new helm and pair of I70 instruments were installed in 2023, along with new macerator pumps. Engine components including motor mounts, manifolds, and mixing elbows were renewed in 2022. Deck equipment includes 225 feet of 3/8-inch chain, a 55-pound Rocna anchor with second backup, code zero sail, and a detachable multipurpose cockpit table. Fresh water systems benefit from Groco AC strainers for the air conditioning units and watermaker.
