Marine Wiring

Marine wiring is the backbone of every electrical system on your boat. Unlike automotive or household wire, marine-grade wiring is built to resist corrosion, handle moisture, and meet ABYC standards for safe use in wet and vibration-prone environments. Using the wrong wire on a boat can lead to voltage drop, overheating, and increased fire risk.

Sonark Marine carries marine wiring, tinned copper boat wire, ring terminals, butt connectors, heat shrink connectors, and other marine electrical wiring supplies needed for new installations and wiring repairs. Whether you're adding electronics, replacing damaged wiring, or upgrading a panel, proper marine wire ensures long-term reliability.

What to Know Before You Buy

Always use tinned copper wire in marine applications to resist corrosion.

Size wire to the correct gauge based on current load and run length.

Use waterproof connectors and heat shrink terminals in exposed areas.

ABYC-compliant wiring protects your boat and satisfies most insurance requirements.
