A repowered Lagoon 380 with 2,900 watts of solar, lithium house bank and Starlink — walked through end to end by her owner.
Some boats are sold on their brochure specs. This 2004 Lagoon 380 Custom PC, named M/Y Herkee, is sold on the thousands of small decisions her owners made while actually living aboard her. The walkthrough video is exactly that: an unhurried, hatch-by-hatch tour narrated by someone who clearly knows where every wire runs.
The headline change is under the sole. The original Volvo 28/30-horsepower engines are gone, replaced by a pair of Yanmar 3JH40s with Yanmar SD60 saildrives and custom exhaust — work carried out by Urbana Boatworks, which owns Remlik Marina where the video was filmed. That repower is what turns a cruising sailing catamaran platform into the power cat configuration described in the listing.
Energy first
Owners who cruise off the dock obsess about power, and this boat reflects it. There are approximately 2,900 watts of solar aboard — seven 370-watt panels plus three 100-watt panels, the latter mounted on a custom stainless arch supporting the bimini. Feeding that is a Victron system tucked under the starboard guest berth: seven lithium batteries, a 5,000-watt inverter and five Victron MPPT controllers. On a good day the owner reports roughly 100 amps going in, and regularly sees 2,200-plus watts in summer.
Monitoring lives at the salon panel: a Cerbo GX display, two BMV-712 battery monitors for the starter batteries, and two Blue Sea panels — a primary 50-amp with a 30-amp sub-panel handling the air conditioner, water heater, a second galley circuit and 12-volt loads. There’s 50-amp shore power in, plus a wired-but-unused 30-amp inlet the owner suggests could serve a battery charger or a second small inverter for a future owner. Shore water input and a transom shower have been added recently.
Ground tackle, canvas and comfort
Forward, a Rocna 55-pound anchor and 150 feet of chain (chain new in 2023) live in the starboard locker, with water jugs and 150 gallons of tankage to port. The trampoline was replaced in 2022 using Dyneema line, and all cabin and head hatches are new. Two large forward lockers double as crash lockers and swallow fuel jugs and fenders.
The custom enclosure was built by Coastal Canvas in Urbana, with the snaps swapped for Sailrite twist locks — a small change the owner rates highly. His practical note is the kind of detail a buyer remembers: on a cold ICW day at 35–40°F outside, the zipped-up enclosure sits around 60°F on solar gain alone.
Electronics and the interior
The helm carries a Raymarine Axiom Pro 12-inch chartplotter, two ST60 instruments, a P70 autopilot control paired with an ACU-400, and a Ray91 VHF with a second handset at the nav station. Two 8-foot Shakespeare antennas serve AIS and radio. Starlink V3 conveys with the boat, running through a Mean Well supply rather than 120V. Inside, the nav desk hosts a 27-inch Dell monitor and Dell Mini PC running OpenCPN as a backup plotter, alongside a PredictWind data hub.
The galley has a double sink with two faucets — one straight from the tanks or shore water, one UV-filtered — an induction single burner, microwave, Keurig, Cuisinart convection oven and a Dometic refrigerator new in 2024. A Webasto 10,000 BTU 110V air conditioner hides under the salon settee, ducted aft to the owner’s cabin. Four cabins are configured to real-world use: port forward as storage with an auxiliary freezer, starboard forward as a tool and stowage room with a safe, a queen guest cabin to starboard aft, and the full-width owner’s queen aft. Both heads are wet heads; the primary shower head is a Raritan Marine Elegance macerating unit added in 2022, while the second is a Nature’s Head composting unit. Tender duty falls to an AB aluminum-hull RIB with a Yamaha 15hp two-stroke bought new in 2024 and used two Bahamas seasons.
Where the model sits
For context, the Lagoon 380 remains an actively traded platform, and buyer interest has picked up sharply of late.

Note that a handful of items shown in the video stay with the owners — tools, personal electronics, the failed washing machine — while the mounted freezer, hanging power-tool rack, printer table, boarding stairs and the outdoor IceGo drinks refrigerator remain with the boat.
