An enclosed helm, fresh electronics, new watermaker and serviced Yanmars make this owner-loved Lagoon 450S ready to point at the horizon.
Step aboard S/V ALOHA and the first thing you notice is how thoughtfully she’s been kept. This 2020 Lagoon 450S, offered by Jeff, is a cruising catamaran that’s clearly been used the way she was designed to be used — and updated where it counts.
Command and Control
ALOHA’s helm sits in a fully enclosed station, tucked out of the weather, which the owner points out helps preserve the electronics — particularly the touchscreen. The nav suite is current: a B&G Zeus chartplotter installed new in 2023, paired with a Halo radar added just this past March. In the walkthrough you can see the radar picking up a squall to starboard, rings set at one- and two-mile intervals, with waypoints, routing and autopilot engagement all a tap away. A Starlink Mini rides at the helm on 12V, giving connectivity anywhere the boat wanders.
Sail handling runs back to the helm through three Harken two-speed 60 electric winches, with the running rigging itself replaced in February. Engine controls, chain counter and instruments are all within arm’s reach.
Twin Yanmars and a Tidy Engine Room
Propulsion comes from a pair of Yanmar 57 hp diesels, one in each hull, last serviced on 6 February 2024. Both engine spaces are notably clean — the owner makes the point that spotless engine rooms make it easy to spot a leak or an issue before it becomes one. The engines look the part: well maintained and cared for.
Power, Water and Systems
ALOHA’s electrical heart is an Onan 13 kW generator in its own sound capsule — quiet enough, the owner notes, that you sometimes forget it’s running. It can be started from the engine room or from the interior main panel. This is a 110V boat, with a new Victron inverter installed in March for silent-ship living when the genset is off.
Fresh water is handled by a brand-new SeaWater Pro watermaker rated at 150 liters per hour, also installed in March and neatly tucked beneath the floorboards in the port aft cabin. In the video the owner demonstrates the entire start-up sequence: power on, booster on, pressure up to 800 psi, water flowing — and an equally simple shutdown.
Even the dinghy hoist got the refresh treatment: a two-speed Harken 40 winch, new in March, makes lifting the tender a one-hand job.

What sets ALOHA apart is the concentration of recent upgrades: chartplotter, radar, running rigging, inverter, watermaker and dinghy winch all touched within the last two years, with the engines and genset freshly serviced. For a buyer who wants to step aboard and go cruising rather than start a refit, that’s a meaningful head start.
