The Impact of Stray Current and Galvanic Corrosion on Underwater Metals

Understanding Stray Current and Galvanic Corrosion in Underwater Metals

Electrical issues like stray current and galvanic corrosion can quietly damage your boat’s metal components. If left unchecked, this corrosion speeds up, potentially leading to expensive repairs. Here’s a quick breakdown of the warning signs and how you can take action to protect your vessel.

Key Signs of Electrical Corrosion:

1. Excessive barnacle growth on metals with certain anti-foul coatings.
2. Coating damage like peeling or blasted-off surfaces due to electrical discharge.
3. Shiny, exposed metal—a sign that electrical current may be at work.

How to Handle It:

Start by consulting a marine electrician to track down the cause of the issue. You’ll want to strip any anti-foul paint off your metal surfaces, as this can worsen the problem. Afterward, coat your underwater metals with a reliable solution like Velox Plus, which provides durable protection and reduces corrosion risk.

By taking the right steps early, you can keep your boat’s metals in top condition and avoid future headaches.
