Boat and Yacht Electrical Repairs

We repair the electrical side of boats and yachts: dead circuits, batteries that will not charge, corroded or chafed wiring, damaged panels, failed shore power connections and equipment that has stopped working, all fixed on board where the boat is kept.

Many searches for boat repairs or yacht repairs are really about electrics, because that is where modern boats most often let their owners down. A lighting circuit goes dead, the domestic bank will not hold overnight, the chartplotter resets whenever the windlass runs, or the shore power trips as soon as the kettle goes on. Those are the problems we fix.

We are clear about what we do not do. Hull, gelcoat, rigging, engine mechanical and woodwork repairs belong to other trades. If your repair list includes those, we will deal with the electrical items and you will need a yard or specialist for the rest.

Repair first, replace only when it makes sense

A repair should start with finding the actual cause. Swapping a breaker or a battery might clear the symptom for a week, but if the real problem is a corroded crimp behind the panel or a charger set to the wrong profile, it will be back. We test methodically, explain what we found, and then recommend the repair.

Sometimes the honest recommendation is replacement. Wiring that has been extended by several owners with domestic cable, an ageing lead-acid bank that no longer holds charge, or a panel with heat damage behind it are cases where patching becomes false economy. We will tell you which category your problem falls into and why.

Common repairs we carry out

The jobs below make up most repair visits:

Mobile repairs at the berth or in the yard

Repairs are done on board, so there is no need to move the boat. We work at marinas, on moorings where there is safe access, and on boats ashore. Please let us know about contractor rules and parking at your marina or yard in advance so the visit runs smoothly.

Our area runs from Brighton to Southampton, including Shoreham, Littlehampton, Chichester Harbour, Hayling Island, Portsmouth, Swanwick and the Hamble.

Repairs after damage and insurance work

Water ingress, flooding, fire and lightning all leave electrical damage that is not always visible straight away. Salt water in particular keeps corroding connections for weeks after the event. If your boat has suffered damage, we can assess the electrical systems, explain what needs repairing or replacing, and put that in writing for you.

We do not claim approval by any insurer. What we provide is a clear written account of the electrical findings and the work required, which you can pass to your insurer or surveyor.

Safety while you wait for a repair

If you smell burning, see smoke, or find cables or terminals that are hot to touch, isolate the batteries and disconnect shore power before doing anything else, and do not use the circuit again until it has been checked. Battery banks can deliver very large currents, and a short circuit can start a fire in seconds. AC shore power carries a real shock risk, especially in a wet environment, so leave faults on that side to a competent person.

Frequently asked questions

Do you repair hulls or engines as well?

No. We handle the electrical systems only. For hull, rigging or engine mechanical work you will need a boatyard or the relevant specialist.

Can you repair electrics after water damage?

Yes. We assess affected wiring, connections and equipment, explain what can be saved and what must be replaced, and give you the findings in writing.

Will you just replace parts until it works?

No. We trace the cause first and explain what we found, so the repair addresses the fault rather than the symptom.

Do I need to bring the boat anywhere?

No. Repairs are carried out on board at your berth, mooring or yard within our area.

Something electrical stopped working?

Describe the fault and send a few photos, and we will come back with the next step.
