What's included
Prism Marine Electric provides grounding, bonding, hull potential & corrosion for yachts, superyachts and sportfish vessels in Fort Lauderdale and throughout Broward, Palm Beach and Miami-Dade County — dockside, at anchor or during a yard period. Licensed, insured and available 24/7, with worldwide travel for vessels under our care.
- Hull potential survey and reference cell readings
- Ground fault detection and tracing
- Bonding system inspection, repair and continuity testing
- Galvanic isolator and isolation transformer verification
- Anode assessment and stray current source isolation
- Insulation resistance testing across AC and DC systems
- Documented findings and remediation plan
Our method
We survey the vessel's hull potential against a reference, then isolate circuits one by one until the leakage source is identified — whether it's a wet junction, a failed submersible pump or a neighboring vessel on the same dock.
Findings are documented with readings so you can show a surveyor, insurer or yard exactly what was wrong and what was corrected.
Signs it's time to call
- Anodes disappearing faster than normal
- Pitting on shafts, props, trim tabs or through-hulls
- Ground fault or isolation alarm active
- Corrosion appearing after a dock or refit change
