Why CL Corp
Marine electrical done right
Bad marine wiring is one of the leading causes of onboard fires. We don’t cut corners.
How it works
Our process
Every job starts with understanding what’s actually on your boat — not guessing.
We start with a thorough inspection of your existing electrical system — checking wiring condition, fusing, battery state, and any existing electronics. We document what we find before touching anything.
Based on the audit, we present a clear scope of work with itemized pricing. No surprise add-ons mid-job. If we find something unexpected during the work, we talk to you first.
Work carried out to marine-grade standards — proper wire sizing, correct fusing at the source, labelled circuits, and secured runs that won’t chafe or corrode.
Everything is load-tested and verified before we sign off. You receive updated wiring documentation and a walkthrough of any new equipment so you’re confident using it underway.
