Complete Marine Electrical Supplies
Boat Navigation Lights – USCG Compliant
Stay safe and legal on the water with USCG-compliant navigation lights from Perko, Aqua Signal, and Innovative Lighting. We carry bow lights, stern lights, masthead lights, and all-around anchor lights for both powerboats and sailboats.
Bow lights include red and green sidelights and are available in fixed and portable options. Stern lights provide white illumination for visibility behind the vessel, while masthead lights are required when operating under power. All-around anchor lights offer 360-degree visibility when anchored.
LED navigation lights are a popular upgrade thanks to their energy efficiency, long lifespan, and brighter visibility.
All boats operating between sunset and sunrise must display proper navigation lights to meet safety requirements and prevent collisions.
Marine Bilge Pumps & Water Management
Protect your boat from water damage with reliable bilge pump systems from Attwood. We carry automatic, manual, and high-capacity pumps along with float switches and accessories for complete water management.
Automatic bilge pumps feature built-in float switches and are available in a range of capacities for different boat sizes. Manual pumps provide a dependable backup option in emergencies. High-capacity pumps are ideal for larger boats that require fast water removal.
We also stock hoses, fittings, strainers, mounting brackets, and check valves to complete your system.
Marine Switch Panels & Electrical Switches
Control your boat’s electrical systems with durable marine-grade switches and panels. Our selection includes waterproof rocker switches, toggle switches, battery switches, and custom switch panels.
Rocker switches are available in multiple configurations and amp ratings, with sealed designs for water resistance. Toggle switches provide heavy-duty performance for demanding applications. Battery switches allow you to manage power between multiple batteries and provide essential safety control.
Pre-wired switch panels offer convenient installation with built-in circuit protection and labeled controls.
Marine Battery Accessories & Power Management
Maintain reliable power with a full range of marine battery accessories. We carry battery boxes, cables, terminals, switches, chargers, and monitoring equipment.
Battery boxes are available in multiple sizes with secure mounting and ventilation. Marine-grade battery cables use tinned copper for corrosion resistance and long-term performance. Battery switches and charging systems help manage multiple batteries efficiently.
Additional accessories include battery monitors, voltage meters, USB charging ports, and 12V outlets.
Marine Grade Wire & Electrical Connectors
Marine environments require specialized wiring and connectors designed to resist corrosion. We stock tinned copper marine wire in a variety of gauges, along with heat shrink connectors and waterproof terminals.
Our selection includes ring terminals, spade connectors, butt connectors, and crimp fittings. We also carry cable management products such as wire loom, cable ties, clamps, and grommets.
Using marine-grade wire ensures long-lasting reliability, while standard automotive wiring can quickly corrode in marine conditions.
Marine Deck Hardware
Complete your boat with high-quality stainless steel deck hardware from Sea Dog Line. We carry cleats, chocks, rail fittings, hatches, vents, and additional deck accessories.
Products include open and closed base cleats, bow chocks, rail fittings, deck hatches, ventilation systems, rod holders, and other essential components designed for durability and corrosion resistance.
USCG Navigation Light Requirements
Proper navigation lighting is essential for safe boating and legal compliance. The U.S. Coast Guard requires specific lighting configurations based on vessel type and size.
Powerboats under 39 feet must display red and green sidelights, a white stern light, and an all-around white light when anchored.
Using high-quality navigation lights improves visibility, prevents collisions, and ensures compliance with safety regulations. LED lighting upgrades provide brighter illumination, lower power consumption, and long-lasting performance.
Boat Electrical System Essentials
Understanding your boat’s electrical system helps with maintenance and troubleshooting.
Every system includes a power source such as batteries, distribution through switch panels, wiring to carry current, and devices like lights, pumps, and electronics.
Common issues include corroded connections, undersized wiring, lack of circuit protection, and poor grounding. Using proper materials and installation methods helps prevent these problems and ensures reliable operation.
Marine Electrical Installation Tips
When installing marine electrical components, always use marine-grade wiring and properly seal all connections. Heat shrink connectors and dielectric grease help prevent corrosion and extend the life of your system.
Navigation lights should be installed according to required height and visibility standards. Bilge pumps should be mounted at the lowest point in the bilge with properly positioned float switches.
Secure wiring properly, avoid sharp bends, and keep wires away from heat sources. For complex installations or high-amperage systems, professional installation is recommended.
Marine Electrical FAQ
What's the difference between marine wire and automotive wire?
Marine wire uses tinned copper that resists corrosion from moisture and humidity. Automotive wire will corrode quickly in a boat’s harsh environment.
Do I need LED navigation lights or are regular bulbs okay?
Both work, but LED navigation lights offer major advantages: 90% less power consumption, 50,000+ hour lifespan, brighter visibility, and no bulb changes for years. Perko and Aqua Signal LED lights are our most popular.
How do I know what size bilge pump I need?
Rule of thumb: 500 GPH for boats under 20 feet, 1,000-1,500 GPH for 20-30 feet, 2,000+ GPH for larger boats. Attwood pumps come in various capacities.
Are Perko navigation lights USCG approved?
Yes, Perko navigation lights meet USCG standards and are approved for use on recreational vessels.
What battery switch do I need for a dual battery system?
A 1-2-Both-Off selector switch allows you to run battery 1, battery 2, both batteries, or disconnect all power. Essential for boats with starting and house batteries.
Can I use regular electrical connectors on my boat?
No, you should use marine-grade connectors with heat shrink or waterproof sealing. Regular automotive connectors will corrode quickly in the marine environment.
