Corrosion Survey & Refit:
A corrosion survey is very important, and yacht owners should conduct one regularly, as unattended corrosion can eat up propeller shaft and metal parts so quickly that it can sink a yacht instantly.

Sailboats
Galvanic Isolator
A galvanic isolator must be installed in series with the boat’s grounding cable in order to prevent stray DC current from passing through.
Polarization Transformer
It is used to electrically isolate the boat’s AC from shore power AC. However, the grounding AC onboard is still maintained.
Isolation Transformer
It is used to electrically isolate the boat’s AC from shore power AC. However, the grounding AC onboard is also electrically isolated.
Reverse Polarity
Reverse polarity is very important for both single-phase and three-phase systems because it can occur, causing injuries or even death.
Powerboats
Grounding System
Incorrect grounding can cause corrosion on a yacht that eventually eats away at its metal parts of the boat, causing it to sink rapidly.
Cathodic Protection System
Anode inspection should be done often. Make sure the cathodic protection system is grounded correctly to the grounding system.
Lighting Protection System
Ensure the lighting system does not interfere with the cathodic system.
Ground Fault Testing
Ensure ground fault protectors and circuit breakers are functioning at a safe threshold when they need to trip.
Recommended Corrosion Parts
A galvanic isolator is bulky and expensive, but it is an effective device to prevent galvanic corrosion that can damage metal components on a boat.
Reverse polarity is important to protect yacht owners and personnel from the risk of electric shock when it occurs in the circuits.
In the event of a ground fault or electrical current leakage, the RCD will trip, shutting down the power source to protect personnel onboard from electric shock hazards.
F.A.Q.
Frequent Questions
How often should yacht owners survey for corrosion?
Yacht owners should survey their yachts for corrosion as often as possible because corrosion occurs every second.
When should yacht owners check their galvanic isolator?
A galvanic isolator is a fail-safe device. When it fails, it still allows the onboard grounding conductor to continue providing grounds.
How to make the lighting system is not interfere with the cathodic protection systems?
Survey and inspection to ensure that the primary and secondary conductors of the light systems do not touch the cathodic protection systems.
How important are ground fault protector device?
Ground fault protectors protect yachts from damage and corrosion. It also protects onboard personnel from electric shock hazards.
