The importance of boat wiring explained.

The rigors of the marine environment, such as vibration, pounding, salty air, engine-space, heat and exposure to chemicals, put a lot of pressure on the wires that are the central nervous system of any modern boat. But we like electricity — a lot — so taking extra steps to ensure our circuits are safe and reliable is a must.

Here’s what you need to know about Marine Grade wire.

Each individual strand of Ancor Marine Grade® wire is fine stranded copper with each strand completely tinned plated for maximum protection against corrosion and electrolysis. The marine wire stranding is unique, the strands are much finer making the wire very flexible, allowing it to better survive in a moving, vibrating boat.

Finally, Ancor’s proprietary premium vinyl insulation is sheathed in thicker insulation designed to stand up in the marine environment; it resists salt water, battery acid, oil, gasoline and ultraviolet radiation and provides greater resistance to heat, shock, water, flame, and chemicals. It is made to American Wire Gauge rather than automotive SAE standards, which makes it 6 to 12 percent larger and therefore able to carry a given amount of current with less heat. Exceeds all UL 1426, US Coast Guard Charter boat (CFR Title 46) and ABYC standards.

Can you use automotive wire in your boat? Yes.
Should you? No.

Here’s Why:
Marine wire is a bit more expensive, but in light of the
other expenses and potential consequences,
it is a wiser investment for your boat.
