Explore serviceWhat we do
Corrosion Control, in practice.
Corrosion & bonding surveys
Every underwater fitting checked end-to-end against the bonding bus, with hull potentials measured rather than guessed.
Ultrasound thickness & grid mapping
Plate thickness mapped where corrosion history warrants it, so decisions rest on numbers.
Reference-cell measurements
Submerged Ag/AgCl readings that separate a healthy hull from a protected-on-paper one.
Stray-current investigations
AC and DC leakage isolated circuit by circuit, shore power included, until the source is found rather than merely suppressed.
Cathodic protection design (ICCP & sacrificial)
Anode mass, placement and ICCP (Impressed Current Cathodic Protection) output engineered against the vessel's actual protection budget.
Deliverables
Every survey leaves the owner with the paperwork.
- Measured hull potentials, logged and mapped
- Photographs of every finding
- A prioritized, costed remediation list
- A written report surveyors and underwriters accept
Galvanic vs. stray current
Two different diseases. Two different cures.
Most “electrolysis” complaints are really one of two problems: galvanic corrosion (dissimilar metals, slow and steady) or stray-current corrosion (a leak in the DC system, fast and destructive). They present the same and fix completely differently, which is why the survey comes before the remedy.
- Galvanic: fixed with bonding, isolation and correct anodes
- Stray current: fixed by finding and killing the leaking circuit
- A proper survey tells them apart in an afternoon
- The wrong fix wastes a haul-out and buys time for the damage
The survey
The corrosion survey, demystified.
Most “electrolysis” complaints are really galvanic or stray‑current corrosion, two very different problems with two very different fixes. The right survey tells them apart in an afternoon.

Common questions
Corrosion Control, asked and answered.
What does a corrosion survey involve?
Reference-cell readings of hull potential, bonding continuity checks on every underwater fitting, an AC/DC stray-current sweep including shore power, an anode and ICCP audit, and a written report with measurements, photos and a prioritized fix list. Most surveys complete in an afternoon dockside.
Why are my anodes disappearing so fast?
Rapid anode loss usually means the protection system is working overtime against a real problem: often stray current from the boat or a neighbor, or a bonding fault. It's a symptom worth measuring before it graduates to running gear.
Do I need to haul the boat for a survey?
No. The diagnostic survey is done in the water, dockside. Haul-out only enters the picture if remediation requires it, and the survey tells you that before you pay for the lift.
