Let me ask you a question.
Does YOUR boat have electrical earth leakage? Chances are that, like most boaters, you don’t know.
DC Earth Leakage….
Hull corrosion can be caused by DC Earth Leakage. The corrosion can happen very quickly. Although it’s a similar process to galvanic corrosion, it often happens much faster.
Usually the pitting is light to begin with, but rapidly becomes much more severe, and can soon lead to a “Sweating” hull. Actually, a sweating hull is much more serious than it might sound, as the “sweating” is actually water entering through microscopic perforations in areas where the metal is heavily corroded.
Your boats anodes are intended to protect it’s metalwork. But if you have DC Earth Leakage problems, your anodes will be the first to go – after all that’s why they’re called “sacrificial anodes”.
So, if your anodes aren’t lasting as long as you expect, this is often a sign of Earth Leakage.
Unfortunately, many boats don’t have sufficient anodes fitted to provide adequate protection, so even boats with new anodes can be damaged by Earth Leakage.
Brass propellers are quickly damaged by earth Leakage. The picture shows a badly corroded prop.
However, the damage doesn’t stop there, because the corrosion often extends to the propeller shaft and bearings.
This is made worse by the fact that a corroded propeller is often out of balance, and can cause vibration.
The MASSIVE problem with DC Earth Leakage is that most people have never even heard of it. From our experience we believe that more than 1 in 3 boats have earth leakage problems.
One of the main causes of Earth Leakage is the technical equipment that we have on our boats, that can send pulses of leakage through the boats electrical system – even when they are working perfectly.
If you have Earth Leakage problems, you almost certainly won’t know about it! DC Earth Leakage will NOT blow a fuse, and it will NOT trip a circuit breaker.
With one of our latest Galvanic Isolators with Status Alert, you would know about Earth Leakage before it could damage your boat. We also provide a simple to follow fault finding guide, and in most cases, you’ll be able to rectify the problem yourself – quickly and easily.
Our Galvanic Isolator with Status alert will tell you if your boat is at risk – AND it protects you from Galvanic Erosion too.
