Sea-Dog 16/2 AWG Duplex Marine Wire 100 ft Red/Yellow
Sea-Dog 16/2 AWG Duplex Marine Wire 100 ft Red/Yellow — Product description
Sea-Dog's 16/2 AWG flat duplex is honest marine wire for the low-draw side of your boat. Two 16-gauge tinned copper conductors in one flat PVC jacket, color-coded red and yellow to the ABYC standard. UL and ABYC certified, wound on a 100-foot spool that covers a full round of nav light and accessory runs.
Rewiring a boat means pulling a lot of wire, and the Sea-Dog 16/2 AWG flat duplex is the kind you reach for on the small stuff. Two 16-gauge stranded conductors ride together in one flat jacket, so a single pull gives you both the feed and the return. That's the wire for nav lights, cabin lights, gauges, and the other low-draw circuits that make up most of a helm.
The conductors are tinned copper, not bare. Out on the water that matters more than almost anything. Bare copper wicks moisture and corrodes green from the cut end inward, and once that happens your connections get warm and your lights get dim. Tinned copper shrugs off salt air and the damp that lives in every bilge, so a run you make today still reads clean voltage years from now.
Red and yellow insulation follows the ABYC DC color code, so the positive leg and the negative return stay obvious the day you wire it and the day someone else troubleshoots it. The flat encasement is the other nice touch. It lies tight against a stringer or up under the gunwale and won't roll around the way a twisted pair does, which makes for a tidy loom you can zip-tie down and forget about.
It's PVC insulated and carries both UL and ABYC certification, so it'll pass a surveyor's eye and hold up to the moisture and abrasion that come with life on the water. Sixteen gauge is sized for lighter loads, so keep an eye on run length. On a long pull feeding a hungrier circuit you'll want to step up to a heavier gauge to keep voltage drop in check. For the short-to-medium runs it's built for, it's honest, no-drama wire.
The 100-foot spool is a practical amount. Enough to knock out a full set of nav light and accessory runs on most boats, or keep a coil in the shop for the fixes that always come up mid-season. If you don't need this much, we stock the same wire in other lengths and color codes.

Frequently asked questions
What is 16/2 duplex wire used for on a boat?
It's sized for the low-current DC circuits that make up most of a helm, nav and anchor lights, cabin and courtesy lighting, gauges, and small accessories. The two conductors carry the feed and the return in one jacket, so you pull one wire instead of two.
Why tinned copper instead of bare copper?
Bare copper corrodes from the cut ends inward once salt and moisture reach it, and corroded strands mean warm connections and dim lights. The tin plating seals each strand, so the wire stays conductive for years in the damp air and bilge water that come with boating.
What do the red and yellow colors mean?
They follow the ABYC DC color code. Red marks the positive leg and yellow marks the DC negative return, so the circuit stays easy to read when you wire it and when someone troubleshoots it later.
Why is the wire flat instead of round?
The flat encasement lies tight against a stringer or up under the gunwale and won't roll around the way a twisted pair does. It makes for a neat loom you can zip-tie down and keep out of the way.
How long a run can I make with 16-gauge wire?
Sixteen gauge is meant for lighter loads over shorter distances. On a long pull or a hungrier circuit, voltage drop adds up, so step up to a heavier gauge to keep your lights and electronics getting full voltage. For the short-to-medium runs it's built for, it does the job.
Is this wire UL and ABYC certified?
Yes. It carries both UL and ABYC certification, so it meets the standards a marine surveyor looks for and holds up to the moisture and abrasion of life on the boat.
