PAIN-0101
Bare-copper corrosion in salt-spray
Standard automotive bare-copper stranded wire fails in marine application — salt-spray + humidity oxidizes the copper green within 6 months, joint resistance climbs, intermittent faults appear.
PAIN-0202
Non-tinned crimp fails ABYC
Non-tinned crimp lug on a marine battery bank fails ABYC E-11 inspection at boat survey — corrosion at the lug-to-cable interface visible after 12 months.
PAIN-0303
NMEA 2000 backbone power undersized
NMEA 2000 backbone built with 4-conductor sensor cable instead of dedicated 4 / 5-conductor power-bus cable — voltage drop on long backbones drops node voltage below 9 V, devices drop off bus.
PAIN-0404
Zinc-plated hardware corrodes
Standard zinc-plated hardware on harness terminations corrodes within 12 months in salt-spray — installer has to remove and replace, voids warranty.

Marine is the only industry where the wire spec is more important than the connector spec. Standard automotive wire (bare-copper stranded) will produce a perfectly-working harness that quietly corrodes from the inside over 6-12 months in salt-spray environment. By the time the customer reports an intermittent fault, half the harness is past saving. We refuse to ship marine harnesses on non-tin-plated wire without explicit customer sign-off — and we audit the wire spool COC at intake to confirm UL 1426 marine spec. The premium over standard automotive wire is 10-15%; the cost of a marine engine rebuild from salt-spray corrosion is at least 100× that.
FAQ · SPEC_QUERIES
Procurement questions.
What is the wire spec for marine harnesses?+
UL 1426 marine cable / ABYC E-11 spec — tin-plated stranded copper conductor with marine-grade insulation. Ancor Marine BC5W2, Pacer BC5W2, Cobra marine series stocked. Standard automotive bare-copper stranded wire is not acceptable for marine applications.
Are you ABYC E-11 inspection ready?+
Yes — every marine harness inspected per ABYC E-11 acceptance criteria. Tin-plated stranded conductor, properly torqued terminal block, no bare-copper crimps, stainless-steel hardware. ABYC certification is held by the OEM / boat manufacturer; we provide the documentation to support the OEM's ABYC certification.
Can you build to NMEA 2000 marine network spec?+
Yes — NMEA 2000 5-pin Micro and Mini connector marine network with proper backbone + drop topology and voltage-drop calculation for the network topology. Drop cables, T-connectors, terminators (120 Ω) stocked. Raymarine SeaTalkNG (NMEA 2000 derivative) and SeaTalk legacy supported.
Will you build marine engine harnesses to OEM specifications?+
Yes — marine engine harness programs for Cummins Marine, Volvo Penta, Yanmar Marine, Mercury, Yamaha, Suzuki, Honda Marine, Caterpillar Marine, MTU. OEM-specific connector pinout, sealing, and qualification per engine manufacturer specification.
Do you support commercial vessel and USV programs?+
Yes — commercial fishing vessel, autonomous surface vehicle (USV), tug, workboat, ferry vessel programs supported with ABYC + classification society (CCS, Lloyd's, DNV GL) documentation. CCS / Lloyd's / DNV GL marine certification documentation per program requirement.
