Marine Electrician & Boat Electrics Darwin

Marine electrician · Winnellie workshop & Darwin Harbour

Wiring, batteries, solar, chartplotters, sounders and radios for tinnies, cruisers, working boats and commercial vessels. Installed and fault-found by someone who spent four years doing it for Wheelhouse Marine.

Salt air, heat and the wet season work everything harder up here. We install for that: proper terminations, corrosion protection and cable that’s sized for the run, not the cheapest reel.

Workshop or on the water

Winnellie & Darwin Harbour

Free consultation and a written quote before any work

Everything electrical on the boat.

Boat wiring and rewires

From a new switch panel to a complete rewire: distribution, breakers, bonding, tinned cable, proper crimps and labelling. Survey-ready where you need the paperwork.

Batteries and charging

AGM and lithium banks, dual-battery setups, isolators, alternator charging, DC-DC chargers and voltage-drop testing so the fridge still runs on day three.

Solar, inverters and shore power

Solar arrays and controllers, inverter and inverter-chargers, shore-power connection with galvanic isolators, and load management for long trips.

Chartplotters and sounders

Garmin, Lowrance, Simrad, Furuno and Humminbird installed, integrated and calibrated. Transducer selection and mounting for Darwin water, radar tied into the plotter.

Radios and AIS

VHF, HF and AIS installed with antennas placed and grounded properly, so they work when it matters.

Autopilot and NMEA networks

Autopilot install and tuning, NMEA 2000 and SeaTalk backbones designed and fault-found, so every instrument talks to every other.

Fault-finding

Intermittent faults, dead circuits, charging problems, instruments that drop off the network. Structured testing and a clear explanation before we proceed.

Lighting and extras

LED cabin and deck lighting, underwater lights, watermakers, pumps, and the accessory circuits that always get added later.

Electronics repaired, not just replaced

Plotters, radios, chargers and switch panels repaired at the board level in our electronics workshop when a new one isn’t justified.

Refits and commissioning

Full and partial refits planned around haul-out windows, sea trials, and documentation handed over so the next person can find their way around.

Starlink on the boat

Internet at anchor or on the move: the right dish for how you use the boat, rail or flat mount, marine cable and glands, and native DC power from the house bank. See Starlink installs.

Look, quote, install, sea trial.

  1. Free consultation

    By phone or at the workshop. Photos of the install area and model numbers of the key gear help us quote faster.

  2. Written quote

    Parts, labour and commissioning itemised. On-vessel visits for diagnosis are quoted separately.

  3. Install and hand over

    Installed, tested, sea-trialled where it matters, and handed over with a wiring diagram and a walk-through at the helm.

What it costs

Travel further afield is discussed up front. See ship repair across northern Australia for larger vessels and remote work.

Common questions

Can you wire my boat from scratch?

Yes. New builds, restorations and full rewires of old boats with a bird’s nest behind the dash are regular work. You get a diagram at the end.

Do you come to the marina?

Yes. Cullen Bay, Frances Bay, Stokes Hill, the ramps and private moorings around Darwin Harbour, plus yards and driveways. On-vessel visits are quoted per job.

Which brands do you install?

Garmin, Lowrance, Simrad, Furuno and Humminbird for electronics; Victron, Redarc and similar for power. We’ll install what you’ve bought, or advise what suits the boat.

Why does everything corrode so fast up here?

Salt, humidity and heat. Untinned cable, bare crimps and indoor-grade gear don’t last a season. We use tinned cable, sealed terminations and corrosion protection as standard.

Can you put solar panels on my boat?

Yes. Panels, a controller matched to the bank, and cabling that survives salt and sun. Sized for what you run, from a fridge on a tinny to a cruiser moored for a month.

Can you fix my chartplotter instead of replacing it?

Often. Plotters, radios and chargers are repaired at the board level in our workshop when the fault is a component, not a cracked screen.

Do you work on commercial and government vessels?

Yes. Working boats, charter vessels and larger ships across northern Australia. See ship repair.

Darwin Harbour, the Top End coast and beyond.

Workshop in Winnellie, a short run from East Arm, Cullen Bay, Frances Bay and Stokes Hill. On-vessel work around Darwin, and scheduled trips along the NT coast for larger jobs.

What helps us quote faster

Photos of the helm, the battery area and the labels on the main gear. Plus any error messages and when the problem started.

Consultation is free. On-vessel callouts are quoted before we come out.
