2008 Lagoon 420

This 2008 Lagoon 420 is a 42-foot fiberglass catamaran with a hybrid-electric propulsion system. Twin electric 72-volt motors rated at 18 hp each provide quiet, efficient cruising at 5 knots typical speed with a maximum of 6.5 knots. The boat is supported by a 21.5 kW generator, 4,000 watts of solar panels, and a sophisticated lithium battery setup comprising a 48-volt house bank and 72-volt propulsion bank. This configuration enables extended off-grid operation, with the generator running approximately one hour per every three to four hours of motoring. Fuel capacity is 160 gallons, allowing a range exceeding 3,000 miles under smart power management.

Accommodations include three cabins arranged for four berths—three doubles plus a saloon berth—with headroom reaching 6 feet 5 inches in the master. Three heads and four showers service the boat, including an external shower on the swim platform. The galley features a central layout with triple sink, dual 12-volt refrigerators, a 12-volt freezer, microwave, and oven/stove combination. An 11-gallon electric hot water system provides freshwater throughout.

Navigation and comfort systems include a Raymarine suite with Axiom 12 chartplotter, depth and wind instruments, radar, and autopilot. Air conditioning operates in both cabins and salon via Dometic and VelAir units, with reverse-cycle heating. A 17 GPH watermaker supports extended cruising, and a 12.5 kW inverter manages onboard power. Standing rigging was replaced in 2022, with running rigging updated between 2022 and 2025. The mainsail is functional with a spare on board, headsail and lightly-used spinnaker are serviceable, and the boat features two-reef helm-controlled main reefing. An upgraded windlass was installed in 2023. A 30 kg Bruce anchor with 70 meters of 10 mm chain comprises the primary ground tackle, backed by spare plow and Danforth anchors. Hull and deck received gelcoat polishing and the bottom was antifouled in January 2025. Safety equipment including a new life raft, EPIRB, and fire extinguishers are current as of 2022.
