Corrosion is caused by stray current and any moisture. Termed electrolysis. Metal electrons are negatively charged. The two negatives repel each other causing electrolysis which dissolves your metal into particles.
Corrosion is dependent on an electro – chemical reaction. Identify and correct the stray current and you will prevent any corrosion from occurring.
SeaBis allows you to correctly identify the CAUSE of stray current corrosion – electrolysis and correct that cause, saving you thousands of dollars in maintenance and repair.

Rust, electrolysis, electrolytic action, marina corrosion, boat corrosion and galvanic are all common terms.
Rust is simply air carried current often vastly accelerated by stray current.
Galvanic is an entirely different process. It is caused by two different metals being in proximity in a conductor such as water. Galvanic is a million times slower than stray current corrosion. Anodes, when stray current corrosion is eliminated, will stop galvanic and should last 3 to 4 years. If they do not then stray current is the cause.
Stray current dissolves your metal
Stray current corrosion to engine leg in 14 days
Stray current corrosion is caused by wiring or equipment defects on board your vessel. I witness stray current destroy commercial propellers and a hull in 10 days, many times every year. It is current flowing from your vessel to the Earth. This is where SeaBis pays for itself, very quickly. SeaBis Master System eliminates that stray current CAUSE. So saving you many thousands dollars.
The stray current thru electrolytic action creates marine electrolysis corrosion. So the original marine corrosion cause is your vessel creating stray current. If you need additional clarification contact us.
It accelerates corrosion making it aggressive and very visible. The result is termed stray current corrosion. The stray current causes electrolysis by electrolytic action. Stray current accelerates rust.
That allows the stray current to create rust. Correcting the CAUSE of stray current reduces rust.
The corrosive ability of stray current depends firstly, on causes in your boat. Second every other boat within at least 180 meters. Third the depth of the water as shallow water causes the Earth to have a increased affect. SeaBis measure the total of ALL stray current. We eliminate the CAUSE of stray current, permanently.
creating an electrical circuit to the Earth. Connecting a battery vastly accelerates that stray current. Creating marine corrosion by metal electrolysis thru electrolytic corrosion. Some call this boat or marina electrolysis or electrolytic boat corrosion or rust.
by electrolytic action – see Wikipedia, electrolysis. The Wikipedia apparatus power is red and black – so supply must be Direct Current (DC or battery current). The Wikipedia text clearly states DC current. Not Alternating Current (AC or inverter or mains or shore power).
for alternating current. It reverses direction every half Hertz or Cycle. A particle removed in the first half Hertz will be replaced in second half Hertz. Therefore AC cannot cause electrolysis. In addition, if there were DC in AC then every AC appliance would burn out in a few seconds as DC has no Back EMF (Counter Motive Force). So do not blame the shore connection.
causes electrolysis by electrolytic action that creates rust. Stopping stray current reduces rust.
that connects to the Earth so creates accelerated marine electrolysis. See Wikipedia, Earth based current –
Explanation: because the Earth provides a current and return path the stray current increases. We must not connect DC to the Earth, via our metal, air or water.
Most importantly stray current is dependent on 3 inputs: moisture, metal and an electrical current. Current explanation down page. The SeaBis System with How To Stop Corrosion permanently stops the CAUSE of stray current that creates electrolytic corrosion.
with SeaBis Master System. By using SeaBis to identify the corrosive ability and the source of the stray current. Next use How To Stop Corrosion to repair or correct the circuit causing it.
First use SeaBis to measure current flow to the Earth. SeaBis indicates stray current ability to cause corrosion. Second, to identify the circuit causing stray current switch off circuits until SeaBis Master indicates Normal (green). The last circuit you switched off was the cause. Finally, follow How To Stop Corrosion.
Eliminates the CAUSE of the stray current that creates stray current corrosion, permanently.
We guarantee SeaBis System for 8 years. How To Stop Corrosion must be complied with. Vast verifiable testimonials are at the bottom of every page.

The SeaBis box proved very useful in tracking down multiple stray current problems aboard our boat. The leading cause was old household wire originally installed by Beneteau and new electronics that had not been earthed correctly. The service from SeaBis was excellent with prompt replies to my queries. I did really appreciate your help. Thanks again for your help, its been A1 service.

Hi Glen, Thanks for your help earlier today. I’ve easily isolated the offending components… spreader lights depth sounder …and the starter motor. I guess the latter is due to carbon build up as it is meant to be a separate earth unit. Anyhow, back on track now. Cheers, Mike

My wife and I are currently circumnavigating aboard our 45 ft. steel yacht. I purchased a SeaBis System after borrowing a friend’s SeaBis and discovering that I, too, had stray current – a flashing red critical light is hard to ignore. This was after the boat had been tested and cleared by the test bulb method. I have no electrical skills but, by following the system, I was able to detect and eliminate the four causes of stray current – a non-isolated genset, a VHF aerial not insulated from the mast, a fuel tank gauge not insulated from the SS day tank, and the connection between a non 12v computer and the SSB radio – to achieve a very satisfying green normal light.
Furthermore, the SeaBis has identified AC leakage from worn brushes in 12v fans and, most recently, a path between the brushes and case on my Balmar alternator, which blew the SeaBis fuse before causing any damage. I consider the SeaBis to be a vital element in diagnosing my yacht’s electrical health. I would also add that Glen has been a great guy to deal with, standing behind his product and providing a wealth of diagnostic advice.

Six years ago I purchased a Dutch barge in Amsterdam, shipped it to the UK and spent four years restoring it to a fully functioning residential boat in my spare time. During this process I learnt much about the ways of vessels which has added to my automobile knowledge. One of the things I learnt was that corrosion was destroying my hull which lead into an investigation, this in turn lead me to the SeaBis. I completed How To Stop Corrosion and time has proven the cause is removed. No more stray current corrosion.

Well Glen your SeaBis system fixed the cause. No problems in 5 months. It was a deck generator and CB radio.

We purchased a steel cruiser 8 years ago and had problems not long after purchase with corrosion on the decks. When the boat was slipped we had evidence of metal corrosion which I think is caused by electrolysis, on the hull as well. When the boat was returned to the water I had a marine electrician check out the boat and he said that our boat was OK and the corrosion was caused by the boat next to us in the marina.
We then believed that was the cause, we tried to get the marina to do something about it but they did not want to know. When the boat was slipped 18 months later the corrosion was that bad we had to sand blast back to bare metal and repaint including the decks. We moved the boat out of marina and put it on a swing mooring, when the boat was slipped again it was evident again. I looked on the web and found the SeaBis site and purchased a unit since then the decks have stopped showing signs of accelerated corrosion. Although we have yet to slip the boat again to check the hull I am confident that the SeaBis unit is performing, as the decks are looking great.

Two Volvo engines with a carbon fibre mast and extensive advanced corrosion to engines. One has previously been replaced. The Owner and Peter traced the cause to a separate power supply in the instrumentation. Fitted an isolating diode and isolating switches to both engines. Problem fixed.
