Sea-Dog 12/2 AWG Tinned Duplex Boat Wire, 100 ft Red/Black
Sea-Dog 12/2 AWG Tinned Duplex Boat Wire, 100 ft Red/Black — Product description
Sea-Dog's 12/2 AWG duplex boat wire gives you 100 feet of tinned-copper cable in a flat red-and-black encasement. Two stranded conductors under one PVC jacket, UL and ABYC certified, ready for the DC accessory runs, lights, and pumps you rig up all season.
This is Sea-Dog's 12/2 AWG duplex boat wire, 100 feet of it, in a flat red-and-black encasement. Two tinned-copper conductors run side by side under a single PVC jacket, so you pull one cable instead of fishing two separate wires through a rigging tube. It's the everyday wire you reach for when you're running a 12-volt circuit to a set of lights, a livewell pump, or a new accessory at the helm.
The 12-gauge size covers a lot of ground on a boat. It handles the moderate DC loads most accessories pull, and the stranded conductors stay flexible enough to route around bulkheads and through tight chases without fighting you. And because it's stranded rather than solid, it takes the constant vibration and flex of a boat without work-hardening and cracking. Red marks positive and black marks negative, so you're not guessing polarity halfway through a run. That color coding saves real time when you come back to troubleshoot a circuit a season later.
What makes this boat wire and not just hardware-store lamp cord is the tinned copper. Every strand is coated in tin, which keeps salt air and moisture from creeping in and corroding the copper the way bare wire does. Bare copper turns green and brittle right at the connections, exactly where you don't want it. Tinned wire holds a clean, low-resistance path for years, and that's why UL and ABYC both certify this construction for marine use.
Reach for it on DC accessory runs, deck and cabin lighting, bilge and washdown pumps, stereo power, and anything else on a two-conductor 12-volt circuit. The flat jacket lies down nicely against a stringer or under a gunwale, and 100 feet gives you enough to wire several circuits or keep a spool aboard for repairs. Strip it, crimp on a heat-shrink connector, and you've got a marine-grade run that'll outlast the accessory it feeds. It isn't shielded cable, so it's not the pick for sensitive electronics data runs. But for straight power-and-ground work, it's exactly what you want.
Key Features

Frequently asked questions
What does 12/2 AWG mean?
It's 12-gauge wire with two conductors bonded together in one jacket. The 12 is the wire gauge and the 2 is the number of conductors, a red and a black.
Is this tinned copper?
Yes. Every strand is tin-coated, which is what keeps salt air and moisture from corroding the copper over time. It's the reason it carries UL and ABYC marine certification.
What's it used for on a boat?
DC accessory circuits. Deck and cabin lights, livewell and bilge pumps, stereo power, and other 12-volt gear that runs on a positive and a negative.
Why are the conductors red and black?
Red is your positive and black is your negative, the standard DC color code. It saves guessing polarity when you wire it in or troubleshoot the circuit later.
How long is the cable?
100 feet, enough to run several circuits or keep aboard for repairs.
Is it flat or round?
Flat. The two conductors sit side by side in a flat encasement, so it lies down neatly against a stringer or under a gunwale.
Can I use it for AC wiring?
It's built and color-coded for two-conductor DC circuits, so this red-and-black duplex is the pick for 12-volt DC work rather than AC.
