What Do Marine Electricians Do?

Key Takeaways

• Marine electricians install, maintain, troubleshoot, and repair the electrical systems on boats, ships, yachts, and naval vessels — covering power generation and distribution, navigation, radar and sonar, communications, lighting, and controls (ElectricianSchoolEDU).
• Most marine electricians fall under the broader electrician category (SOC 47-2111), which reported a median annual wage of $63,190 in May 2025, with the top 10% earning more than $108,510 (U.S. Bureau of Labor Statistics).
• The ABYC Marine Electrical Certification is the most widely recognized credential in the field, built around the ABYC E-11 standard for AC and DC electrical systems on boats.
• Overall electrician employment is projected to grow 9% from 2025 to 2035 — faster than average — with roughly 72,700 openings each year (U.S. Bureau of Labor Statistics).
• The U.S. Navy’s roughly $47 billion FY2026 shipbuilding request is among the largest in decades, fueling demand for skilled trades at shipyards (Congressional Research Service).
• Shipbuilders are hiring hard to close a labor gap: Huntington Ingalls added about 2,400 workers in a matter of months and raised wages to attract experienced tradespeople (WHRO).

Marine electricians keep vessels powered, navigable, and safe. They install and repair the systems that run everything from a yacht’s cabin lighting to a warship’s radar array. It is a specialized branch of the electrical trade, alongside niches like solar farm electricians and data center electricians. Marine electricians work in wet, salty, confined shipboard spaces where a failure at sea can be life-threatening. With the U.S. Navy requesting roughly $47 billion for shipbuilding in FY2026 and shipyards scrambling to fill skilled-trade openings, according to the Congressional Research Service, demand for electricians who can work afloat and in dry dock is climbing. This guide explains what marine electricians do, where they work, the certifications that matter, and how to break into the field.

What Marine Electricians Do

Marine electricians install, maintain, troubleshoot, and repair the electrical systems that keep a vessel running. Unlike a building, a ship generates and distributes its own power, so the work spans everything from the main switchboard to the smallest cabin fixture. On any given day, a marine electrician might handle the following:

• Install and maintain power generation and distribution systems, including generators, switchboards, and shore-power connections
• Wire and service navigation systems, radar, sonar, and communications equipment
• Install and troubleshoot lighting, alarms, and monitoring and control systems
• Service propulsion motors, battery banks, inverters, and charging systems
• Diagnose electrical faults and corrosion-related failures, then repair or replace components
• Document inspections, repairs, and maintenance to meet safety and regulatory standards

Because a vessel is a self-contained electrical environment surrounded by water, reliability is safety-critical. A short, a grounding fault, or stray current can leave a crew without navigation or communications far from shore, corrode underwater metals, or endanger swimmers. So precision and code compliance matter more than on a typical job site.

Where Marine Electricians Work

The field splits broadly into recreational and commercial marine service on one side and shipyard and naval shipbuilding on the other. Recreational and commercial electricians tend to work aboard existing vessels, while shipyard electricians install or refit systems in hulls that are being built or are in dry dock for major work.

Naval shipbuilding is concentrated in a handful of regions like the Hampton Roads area around Newport News, Virginia, and Gulf Coast yards in Mississippi and Alabama, where large defense contractors build and maintain the fleet.

Skills, Certifications, and Standards

Marine electrical work rests on a core electrical foundation plus marine-specific knowledge. The most recognized credential is the ABYC Marine Electrical Certification, which is built around the ABYC E-11 standard governing AC and DC electrical systems on boats. Certified marine electricians learn to size wiring correctly, protect circuits, terminate connections to prevent overheating, and eliminate the stray currents that corrode underwater metals or endanger swimmers. For a broader overview, see our guide to the skills and certifications electricians need.

Beyond ABYC, employers typically look for:

• Core electrical training and, in many roles, a state journeyman or master license
• NFPA 70E electrical-safety knowledge and OSHA safety training
• Familiarity with marine standards and U.S. Coast Guard requirements for commercial vessels
• The ability to read electrical schematics and one-line diagrams
• A security clearance for naval and government shipyard work, which many defense contractors require

Work Environment and Hazards

Marine electricians work in some of the trade’s most demanding conditions. Salt air and seawater accelerate corrosion, so systems degrade faster and demand more inspection and maintenance than land-based equipment. The work happens in tight, confined spaces (engine rooms, bilges, and equipment compartments) sometimes while a vessel is afloat and moving, and sometimes in a dry dock where the hull sits out of the water for major refits.

Here's how marine electrical work differs from land-based electrical work:

Marine Electrician Pay and Job Outlook

Because the BLS does not publish a separate wage for marine electricians, they generally fall under the broader electrician occupation (SOC 47-2111), which reported a median annual wage of $63,190 in May 2025. The lowest 10% earned less than $42,640 and the highest 10% earned more than $108,510, according to the U.S. Bureau of Labor Statistics. Actual marine pay varies with vessel type, certification, region, and whether the work is recreational service, commercial, or defense shipbuilding, where clearance-holding tradespeople often command a premium.

The outlook is strong. Overall electrician employment is projected to grow 9% from 2025 to 2035, faster than average, with about 72,700 openings a year (U.S. Bureau of Labor Statistics). Layered on top of that, the naval shipbuilding surge is intensifying demand for marine-capable electricians. The Navy’s roughly $47 billion FY2026 shipbuilding request is among the largest in decades (Congressional Research Service), and yards are struggling to staff up after years of retirements and thin trade pipelines (National Defense Magazine). Huntington Ingalls, the nation’s largest military shipbuilder, added about 2,400 workers in a matter of months and raised wages to attract and retain skilled trades (WHRO), and it plans to distribute more than 2.5 million hours of shipbuilding work across other facilities in 2026 to keep pace with demand (USNI News).

How to Get Started as a Marine Electrician

Most marine electricians start with a solid electrical foundation, then add marine-specific training. If you already hold an electrical license or apprenticeship experience, the transition is mostly about learning DC systems, corrosion control, and marine standards. If you are just entering the trade, you can even become an electrician straight out of high school. Practical steps include:

• Build core electrical skills through an apprenticeship or trade program
• Earn the ABYC Marine Electrical Certification to signal marine-specific competence
• Add NFPA 70E and OSHA safety training, which most employers expect
• Target the setting that fits you: marinas and boatyards for recreational work, or shipyards for commercial and naval builds
• For naval work, be prepared to obtain a security clearance
• Search boatyards, marinas, and major shipbuilders, and job boards like Buildforce, for openings.
