Marine electrolysis corrosion prevention.

Photographic proof the SeaBis Master System with How to Prevent Corrosion will prevent 97% of corrosion.

The first photo is of Utopiall hull on the hard (slip) before SeaBis installed.  Therefore, see the corrosion causing hull to dissolve.

The second and third photos are a year submerged.  After SeaBis Master System prevented the causes. Therefore, see no hull corrosion.  After that, antifouling works as designed.

In addition, none are caused by galvanic (nearly touching different metals) corrosion.

Galvanic corrosion examples are a stainless-steel ladder leaning against an aluminum hull.  Stainless-steel knob on aluminum cupboard. Easily prevented. Contact us.

When SeaBis Master System prevents ALL the CAUSES.  There MAY remain galvanic corrosion at 3% of total.  Galvanic corrosion is easily prevented when electrolysis at 97% is prevented FIRST.  In conclusion, we will guide you.

Proof that we say is true:
Marine electrolysis corrosion prevention by SeaBis Master System works 100%.

For the curious:

Very few pretty pictures.  Just the hard facts. 

Now, one hard fact:  Please consider automotive vehicles. 

Corrosion in automotive vehicles is mostly prevented.  Because they are on rubber tires, so insulated from the Earth.  SeaBis Master System has the same effect. The result will be total insulation from the Earth and those around you. SeaBis will indicate Normal (green). Permanently. No additional coating, plating, moving parts or penetration. We prevent the CAUSE. How to Prevent Corrosion must be complied with.


* SeaBis may be made portable by fitting battery clips, with limitations:

One SeaBis Master with battery clips can be moved battery bank to battery bank or boat to boat. All wires, including Current Sense, – green/yellow, may be extended hundreds of meters.  Note: * SeaBis indicates stray current on the circuit it is connected to.  Therefore, not on battery banks while moved elsewhere – connected elsewhere.  Intermittent or new causes MAY occur while connected elsewhere, so require permanent installation. *

*  The number of battery banks being monitored by SeaBis Master may be increased:

By using * Battery Switches “Both” or “Emergency”. So paralleling battery banks. *** ONE SeaBis Master will monitor them all. ***

* Tipping point where corrosion is self-propagating:

As the surface becomes roughened so stray current increases, so corrosion increases …. Prevent the CAUSE with SeaBis Master System as soon as possible.

Hint: growth increases as surface roughens. As the surface roughens the area increases, so stray current increases.  So, when you see growth increase, check for corrosion.

SeaBis Master System Money-back guarantee and warranty with free diagnostic support are for 8 years.  How to Prevent Corrosion must be complied with.


Prevent the ONLY CAUSE of marine electrolysis corrosion, stray current, in 3 easy steps:

Marine electrolysis corrosion prevention by SeaBis Master System.


Step 1 of 3.  

Identify the types of corrosion SeaBis Master System prevents.  From the photos in the above carousel.

All CAUSES are prevented by SeaBis Master System. Permanently.

The button is full size photo is Royal Albatross.  She is an old Tanker hull.  Similarly, proof that age does not cause electrolysis.

Step 2 of 3.  

Understand the CAUSE:

Wherever there is a battery (batteries must be DC) or Direct Current (DC) supply and current leakage to the Earth, stray current flows.  Above all, stray current is the ONLY cause of marine electrolysis corrosion.

External proof:  Wikipedia electrolysis.  Wikipedia specifically states DC – battery power.  NOT AC – shore power.

Therefore, when we prevent the DC that is the ONLY CAUSE of stray current, we prevent the corrosion. That is why we 100% succeed. Guarantee.

Step 3 of 3. 

Prevent the CAUSE, stray current, Permanently:

Marine Electrolysis Corrosion Prevention Procedure:

Install SeaBis Master:

Connect to SeaBis Master:

1:  Brown to battery positive

2:  Blue to battery negative

3:  Green / yellow to metal hull or metal engine body

SeaBis Master System prevents the CAUSE of electrolysis corrosion.

ALL Battery positive indications – contact us immediately. Especially if you have both 12 and 24 volts. Fire risk can be eliminated.

Corrosion CAUSE prevention procedure:

SeaBis Master LED’s explanation:

Marine electrolysis corrosion prevention by SeaBis Master System, in action.

Your work is reduced by half: 

SeaBis Master indicates battery side with the fault/s.  “Battery positive” or “Battery negative”.
1:  Normal, either (green) = the stray current is far below corrosive threshold.  It cannot cause corrosion
2:  Caution (amber) = very low current.  There is risk a fault can become serious
3:  Serious (red) = visible corrosion in 6 months
4: Critical (flashing red) = visible corrosion in 3 months
5:  AC Only (flashing red) = your batteries, electronics and yourself are at risk.  Excessive AC (110/240) on top of DC (battery). Common cause is power supply Active, Neutral or Earth reversed so your life is at risk.
All battery positive LEDs then contact us immediately.  There is a fire risk that can be prevented.

After that, observe SeaBis indicators:

For instance, if you see other than either Normal (green) then the stray current is ongoing.  In addition, SeaBis Master indicates the side of the battery causing stray current. Therefore, halving your work. According to Bat + or Bat – indicator: Switch off / disconnect circuits on battery positive OR negative until you have a Normal.  Above all, when either Normal is On there is no stray current

The last circuit you switched off was a cause of stray current

Consequentially, leave it switched Off

After that, to determine if there are any other causes, momentarily switch On the remainder, one at a time

Then, any that cause other than Normal, leave switched Off.  Switch ON all that indicate Normal

In conclusion, you will have one or more circuits switched off / disconnected.  After that, see what has no power, and you will know the cause/s.

Printed How to Prevent Corrosion with causes and prevention, supplied with SeaBis Master System. Including generic wiring diagram.

To repair the CAUSE of stray current: follow How to Prevent Corrosion instructions or Contact Us.

Above all, now there can be no stray current, so no marine electrolysis corrosion, permanently.

Marine electrolysis corrosion prevention by SeaBis Master System, completed.


Can shore connection – AC – inverter or shore power be a cause?

Proof that marine electrolysis corrosion is ONLY CAUSED by stray current – DC or battery power.  Never AC or shore power:

  1:  External proof by Wikipedia:

Battery power – Direct Current (DC) is the ONLY cause of stray current corrosion. Via air and water. In addition, look at the color of power leads to apparatus. Red is DC positive and black is DC negative. Proof HERE.

  2:  In addition, do not waste your money:

A Blocker, is in the AC power supply, so will not stop stray current corrosion. It will increase the risk of electrocution and allow corrosion to escalate: DC is the ONLY cause of stray current.  Reason: DC cannot exist in AC (shore or inverter power). AC reverses current direction every 1/100 second.  IF it takes off a partial in the first 1/100 second, it will put it back on again in 2/100 second. SeaBis Master will indicate DC in AC by flashing red. Explanation HERE.

  3: Similarly, external proof by yourself: 

AC (shore power) in DC:  Read the specification on your electric kettle / pot / hotplate / mains power appliance. There will be no DC entry. Therefore, it has no DC tolerance. In conclusion, IF there were DC in the AC, there is no Counter Motive current (Back EMF) therefore the appliance would attempt to draw infinite current. It would burn out in a few seconds.  Additional proof explanation Counter Motive Force (Back EMF) HERE.

IF there is DC in the AC, then SeaBis Master will indicate it by flashing red.
Marine electrolysis corrosion prevention by SeaBis Master System, works 100%.


 4:  In addition, it is far lower cost to prevent stray current corrosion than repair – see:

“I had no marine electrolysis corrosion until a few weeks ago” – solution follows:

Cause: As the metal becomes rougher, so its surface area increases. That increases the stray current flow. Therefore, increasing corrosion, cumulatively. I have witnessed a 10-day time period from no to extreme corrosion far too many times. In many instances, two of US$5,000 propellers were corroded beyond repair in 10 days.
Solution:  Therefore, employ SeaBis Master System with How to Prevent Corrosion. Prevent the stray current that is the ONLY cause, NOW
Conclusion:  The CAUSE is repaired, resulting in no stray current, so no marine electrolysis corrosion.

5: In conclusion, if you cannot prevent the CAUSE, then CONTACT US, and we will guide you – free.


Above all, marine electrolysis corrosion CAUSE prevention.

Before SeaBis Master System:

Marine electrolysis corrosion is ongoing.  It is ONLY caused by stray current.  It causes metal to dissolve, therefore the coating bubbles.   In conclusion, ALL metal, everywhere onboard, conducts the stray current. Via air and water. After that, it attacks everything it has access to. Via water and air: propeller, gearbox, engine, hull, deck rails, mast and cross trees – all metal.
Hull dissolves
Before SeaBis. Marine electrolysis corrosion prevention would have prevented the air carried stray current.

After SeaBis Master System:

Marine electrolysis corrosion prevented.  Permanently.  Above all, no stray current therefore, no metal dissolved. Therefore, no bubbles.  After that, Antifouling can work as designed.  No growth. 
In addition, no additional coating, plating, penetration or moving parts.  
In conclusion, SeaBis Master System prevents ALL marine electrolysis corrosion. Permanently.
After SeaBis. Antifouling works as designed.
After SeaBis. A year submerged. Marine electrolysis corrosion prevention identifies then prevents the stray current that is the only CAUSE. Permanently. Antifouling works as designed.
After SeaBis. No stray currents. Antifouling works as designed.
After SeaBis. Underwater view. A year submerged. Marine electrolysis corrosion prevention stops ALL stray current. Antifouling works as designed.

Real life movie follows.  Made, to say thank you, by the yacht Owner:

An extremely complex commercial yacht.  In conclusion, ALL causes of marine electrolysis corrosion are prevented. Permanently.
In addition, most vessels need only one SeaBis Master.

Marine electrolysis corrosion prevention corrects the CAUSES of stray current. So, preventing the CAUSES of corrosion.  Real life movie:

Galvanic Corrosion is the remaining 3% :

There is only ONE cause for galvanic corrosion:    That cause is differing metals such as Aluminum and Stainless Steel that are touching or very close to touching in another than dry environment.  In conclusion, there is no other cause of galvanic corrosion.  Permanently.

Marine electrolysis corrosion accelerates galvanic corrosion on at least a 1,000:1 ratio.

Therefore, electrolysis corrosion must be prevented BEFORE preventing galvanic corrosion.  After that, galvanic corrosion is easy to prevent by insulation, separation or anode/s.

For instance:  Leaning a stainless-steel ladder against the hull of an aluminium vessel will generate galvanic corrosion.  That dissolves the hull, at the point, the stainless steel ladder touches the aluminium.  Similarly, stainless steel handles on an aluminium cupboard will cause the aluminium to dissolve. Insulating the stainless steel from aluminium, at the point of contact, will prevent the CAUSE of galvanic corrosion. Therefore, marine electrolysis corrosion must be prevented first.

In conclusion, we will assist for a minimum of 8 years – free.

First, prevent the stray current that is the ONLY cause of at least 97% of marine electrolysis corrosion.  After that, prevent the 3% galvanic corrosion.  Corrosion causes will recur; therefore, we will provide free diagnostic support for a minimum of 8 years.
