Ancor Dark Blue 18 AWG Tinned Copper Wire - 100'

Ancor Dark Blue 18 AWG Tinned Copper Wire in 100-foot spools is purpose-built marine electrical wire that exceeds UL 1426, ABYC, and US Coast Guard Charter Boat (CFR Title 46) standards. This is the wire you run through your boat's wiring harness—engine compartment to distribution panels, navigation systems to battery banks—where saltwater exposure and thermal cycling demand absolute reliability. Tinned copper construction resists corrosion in marine environments far more effectively than bare copper, making this the standard choice for any vessel that needs wiring that won't fail at sea.

The 18 AWG gauge handles typical bonding, accessory, and low-amperage circuits on fishing boats and cruisers without voltage drop issues over moderate distances. Premium vinyl insulation is rated 600V and remains flexible even at extreme cold (-40°F), resisting salt water, battery acid, oil, gasoline, heat, abrasion, and UV radiation—conditions you face every season on the water. The 100-foot spool provides enough wire for rewiring smaller systems, making repairs to existing runs, or adding new circuits without needing multiple spools for a single project.

Serious anglers upgrading fish finders, GPS systems, or LED lighting; weekend boaters repairing corroded factory wiring; and offshore fishermen building custom electrical layouts all reach for Ancor marine-grade wire. The dark blue color aids troubleshooting and system documentation. Whether you're a DIY boater tackling annual maintenance or a fishing charter operator ensuring systems reliability, tinned copper wire meeting Coast Guard standards eliminates guesswork about whether your electrical work will hold up to salt air and constant vibration.
