The Ancor Red/Black 14/2 AWG Flat Duplex Cable is a 100-foot length in a common jacket with Type 3 ultra-flexible stranding.
A hundred feet of 14 gauge duplex covers one circuit out and back, or a pair of short ones. That suits adding a light run, a small pump or an accessory circuit to an existing system, where the larger spools would leave most of themselves unused.
Fourteen gauge is fine at moderate lengths and marginal once a circuit runs forward and back on anything drawing real current. Voltage drop is what limits it rather than current capacity, and the symptom is a dim light or a slow pump rather than a blown fuse.
Red and black follows the traditional convention, matching what most existing boat wiring uses. The flat profile routes neatly against panels and bulkheads, and ultra-flexible Type 3 tinned copper stranding resists corrosion while tolerating vibration and repeated flexing.
