Boat Wiring & Rewire Services for Boats and Yachts
When your boat’s wiring is unreliable, everything onboard becomes a risk. We provide professional marine wiring, rewiring, panel upgrades, and fault diagnosis for boats and yachts, wired to ABYC standards so your electrical system performs safely and reliably every time you leave the dock.

Professional Marine Wiring and Rewiring Onboard Your Vessel
Our wiring services cover the full lifecycle of your boat’s electrical system, from diagnosing faults in existing wiring to partial rewires, full rewires, and new circuit installation. This includes AC and DC wiring, distribution panels, bus bars, shore power connections, grounding and bonding, and the correct routing and protection of every run onboard.
Marine wiring is not the same as household wiring. Onboard cabling has to survive constant vibration, salt air, moisture, heat, and flexing, all while carrying power reliably across a vessel that is always moving. Wiring that was fine on installation day can corrode, chafe, and loosen over years of use. A proper marine wiring job is not just about making a circuit work today. It is about making sure it stays safe and reliable for the boat owners who depend on their vessels the most.
Common Wiring Jobs We Handle
When your wiring starts causing problems, it rarely stays a small problem.
You rely on your electrical system for navigation, communication, lighting, pumps, refrigeration, and the systems that keep your vessel running.
Faulty wiring does not just cause inconvenient failures. It is the leading cause of onboard electrical fires. Whether you run your boat professionally, cruise long distances, or keep a vessel that has to perform on demand, your wiring needs to be right.
Good wiring is invisible when it works and dangerous when it does not. Our job is to make sure yours is done to standard and built to last.

How Marine Wiring Fails in Boat and Yacht Usage
Most wiring problems we see are not sudden. They build slowly, as connections corrode, insulation wears, and years of vibration loosen terminals that were once tight. By the time a symptom appears at the helm, the underlying issue has often been developing for a long time.
Common real-world problems include:
- Corroded terminals and connectors
- Chafed or damaged insulation
- Undersized wiring causing voltage drop
- Loose connections from constant vibration
- Non-compliant or unsafe previous installs
- Water intrusion at cable runs
- Overloaded or outdated panels
- Intermittent faults that are hard to trace
- Melted or overheating connections
- Improper grounding and bonding
- Backfed or incorrectly wired circuits
- Aftermarket additions wired incorrectly
These problems often show up as something small. A circuit that works intermittently, a breaker that trips for no clear reason, or a light that flickers underway. Left alone, faulty wiring becomes a system you cannot trust and, at worst, a genuine fire risk onboard.

Our Services in San Diego and Internationally
Core / General Electrical Repair
Power loss, intermittent electrical issues, or system faults anywhere on the vessel. Battery inspections and replacements, charger and inverter troubleshooting, transfer switch repairs, AC and DC system diagnostics, wiring corrections, panel upgrades, and full system overhauls to restore safe and reliable onboard power.
Fishing Boat Electrical Equipment Repair
Sounders and transducers not reading accurately. Bait tank pumps losing pressure or failing. Fish box macerators and ice chippers not operating properly. Downrigger and outrigger electronics malfunctioning. Deck and work lighting issues that affect visibility and safety during early departures or late returns.
Navigation Equipment Repair & Installation
Chartplotters, radar systems, AIS, wind instruments, depth sounders, and full onboard network integration. Radar not powering up or not displaying on your chartplotter. GPS position dropping out. Autopilot not syncing. Your navigation electronics not communicating properly across the system.
Battery / Inverter System
Battery banks, inverter and charger systems, and full DC to AC power integration. Inverter not powering outlets or tripping under load. Batteries not holding charge or draining too quickly. Shore power not charging properly. Your onboard systems losing power unexpectedly or not supplying clean, stable energy throughout the vessel.
Why ABYC-Compliant Wiring Matters
Wiring is one of the few areas onboard where the difference between a good job and a poor one is invisible until something goes wrong. As an ABYC-certified marine electrician, every wiring and rewire job we complete is done to American Boat and Yacht Council standards, the same standards insurers and surveyors rely on. That protects your vessel, protects its value at survey, and protects the people onboard.
