Corrosion CAUSE prevented in 3 steps, permanently.
How to prevent electrolysis, corrosion CAUSE in 3 steps, permanently.
Step 1: Identify
97% of marine corrosion is caused by electrolysis. 3% by galvanic.
Marine electrolysis is ONLY caused by stray current. It is the CAUSE of all the following:
Paint bubbling. Marine electrolysis caused by stray current
Propeller corrosion caused by stray current creating electrolysis. Stainless steel forms worm holes.
Electrolysis created by stray current corrosion to engine leg in 14 days
Weld attracts stray current corrosion
Electrolysis dissolves the metal under the paint
Typical electrolysis white growth.
How To Prevent Electrolysis Instructions with SeaBis System corrects the CAUSE.
Marine electrolysis corrosion is caused by stray current. I witness that stray current destroy propellers and hulls in 10 days, many times every year. Most importantly, wiring or equipment defects on board your vessel cause the stray current. The resulting stray current flows from your vessel to the Earth. SeaBis Master System pays for itself, very quickly, correcting the stray current CAUSE. So saving you many thousands dollars.
Step 2: Understand
How to stop marine corrosion and electrolysis.
Stray current – electrolytic corrosion CAUSE eliminated
Most importantly stray current is dependent on ALL of 3 inputs: moisture, metal and an electrical (stray) current. Therefore elimination of stray current prevents corrosion.
In conclusion the SeaBis System with SeaBis Instructions permanently prevents the CAUSE of stray current that creates marine corrosion by electrolysis.

We will step you thru it.
Step 3: Eliminate
How to prevent electrolysis and corrosion:
First use SeaBis to measure current flow to the Earth. Observing the lights on SeaBis. Second, identify the circuit causing stray current by switching off circuits until SeaBis Master indicates Normal (green). The last circuit you switched off was the cause. Finally prevent the CAUSE, follow SeaBis Instructions. Then our 8 year guarantee applies.
Galvanic is easily prevented when electrolysis – 97% is eliminated. We will step you through it.
Questions and answers:
Do you doubt corrosion is caused by stray current?
Then see Wikipedia, electrolysis. You will see the Wikipedia apparatus power is red and black – so must be Direct Current (DC or battery current). Wikipedia text clearly states DC current. Wikipedia does not state Alternating Current (AC or inverter or mains or shore power). So shore power or AC cannot be the cause.
Anodes? Can I add more to prevent corrosion?
A one kilo gram (1,000 grams) or two pound anode generates 1/(divided by)1,000,000 or one millionth of an amp protective current. Whereas stray current is 100 to at least 1,000,000 times stronger. Therefore you would need 100 too at least 10,000 kilo grams of anode! So use SeaBis Master System to prevent the CAUSE, completely and permanently.
Multi meter, half cell, reference electrode or test lamp? Can any of them prevent corrosion?
Sorry but no. The consequence will be to waste your time and money while corrosion escalates. The reason is corrosion is caused by CURRENT flow to the Earth. They will measure the COMBINED VOLTAGE of every vessel within 200 meters and that of the Earth. The result is misleading information. Therefore use SeaBis Master System to measure current flow to the Earth and correct the cause – it works 100%. That is why we provide a 8 year guarantee.
Why buy a Blocker?
Some will try confusion by calling Blocker a Galvanic Isolator! Don’t be deceived. AC – Mains / shore power CAN NOT be the cause.
Ask for their WRITTEN guarantee. Read it.

AC or shore power cannot be the cause so what does the Blocker achieve?
AC is the abbreviation for Alternating Current. It reverses direction every half Cycle or Hertz. So IF a particle is removed in the first half Cycle it will be replaced in second half Cycle. Therefore AC cannot cause electrolysis. In addition, if there were DC in AC then every AC appliance would burn out in a few seconds. The reason is: DC has no Counter Motive Force (Back EMF). So do not blame the shore connection. The SeaBis System will correct the cause.
How to prevent electrolysis and stray current:
First the corrosive ability of marine electrolysis depends on causes in your vessel. Also every other vessel within at least 180 meters. In addition water depth less than 180 meters causes the Earth to have a corrosive effect. SeaBis measures the TOTAL stray current affecting your vessel ONLY. Now use the SeaBis Master System to prevent the CAUSE of stray current, permanently. So preventing other vessels from causing you electrolysis corrosion. Therefore preventing nearly all corrosion. Galvanic corrosion is only 3 % and easily prevented when the cause of electrolysis is corrected.
Rust cause:
Air carries stray current causing rust. Preventing stray current reduces rust. Use SeaBis!
More proof:
Wikipedia explains the cause: See Wikipedia, Earth based current – the Earth provides a current and electrical path that causes the stray current to increase. In addition, both water and air are conductors. So they complete the circuit to the Earth. Now correct the CAUSE: Use the SeaBis Master System to identify and PREVENT the cause.
SeaBis Master System prevents CAUSE of stray current – electrolysis.
Common names are rust, electrolysis, electrolytic action, marina corrosion, boat corrosion and galvanic. The CAUSE is always the same – stray current creates marine electrolysis caused by faults on your boat. The solution is to use SeaBis Master System to Identify, understand, then eliminate the cause, permanently.
Marine electrolysis is caused by stray current flowing from your vessel to the Earth. This is where SeaBis pays for itself, very quickly. SeaBis Master System eliminates stray current CAUSE. So saving you many thousands dollars.
What is electrolysis? Electric current attracted to the Earth (we stand on) carrying your metal with it to the Earth.
What is rust and galvanic corrosion? Rust is simply air carried current often vastly accelerated by stray current – electrolysis. Galvanic corrosion is a minority cause and caused by two different metals being in proximity in a conductor such as water. Galvanic is a million times slower than stray current corrosion – electrolysis. Anodes, when stray current corrosion is eliminated, will prevent galvanic and should last 3 to 4 years. If they do not then stray current is the cause. Galvanic corrosion is vastly accelerated by electrolysis.
What is the solution? This is where SeaBis pays for itself, very quickly. SeaBis Master System prevents stray current CAUSE. So saving you many thousands dollars.
It is much cheaper to identify then correct the CAUSE now, than wait until corrosion roughens so increases surface area and stray current increases. That stray current dissolves your metal to the Earth, increasing with increased surface area.

Testimonials
The SeaBis box proved very useful in tracking down multiple stray current problems aboard our boat. Old household wire was the leading cause. It was originally installed by Beneteau and new electronics that had not been earthed correctly. 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.
Andrew Deeley / SV Utopia II
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 SeaBis Instructions 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.
