Marine corrosion prevention, permanently

Since when I bought my sailing yacht in Spain in 2009 I noted some faster than usual corrosion at some specific places like inside anchor compartment and rudder compartment (below deck) even with my poor knowledge of metal boats at that time. Other corrosion issues became visible after the new electronics and new engine installation in 2014.

After a long search of electrolysis causes and repairs, I found SeaBis electrolysis control system in a net sailing forum.

I contacted Mr. Glen from SeaBis in December 2016 and purchased 4 SeaBis Master units. I have material to show how the entire process took place, like “before and after” pictures.

This picture below shows the boat on hard in Curaçao 9 months after anti-fouling repainting and new electronics and new engine installations, end of 2013. The hull under the waterline is completely full of blisters. The shooting was taken in September 2014.

Mr Glen confirmed these blisters were caused by electrolysis. But much more is yet to come.

We exchanged more than a hundred emails in one week during December 2016. Questions were made and doubts solved one by one.

Mr. Glen instructed me to install the units as follows:

one – House

Bank one – Engine Bank

one – Windlass

one – Bow Thruster

Before SeaBis electrolysis corrosion prevention system.  Hull dissolves, so, anti-fouling bubbles:

before the seabis electrolysis prevention system. Hull dissolves.
Before SeaBis. Yacht Utopiall hull dissolve. Therefore, antifouling lifts. Marine electrolysis corrosion prevention would have prevented the only CAUSE - stray current. Permanently.

After one year submerged.  No blisters !!!!:

Here is the scenario before and after SeaBis electrolysis corrosion prevention system repair:

BOW THRUSTER

Situation:  

 

critical electrolysis on positive side(red flash).

Cause:        

 

DC 12V to 24V converter(poor design).

Repair:       

 

device removed.

After action:

WINDLASS

 

electrolysis eliminated.

Situation: 

 

critical electrolysis on negative side(red flash).

Cause:        

 

windlass DC electric motor negative brushes not

  

insulated.

Repair:       

 

installation of remote solenoid on windlass 

  

electric motor negative wire.

After action:

 

momentary critical electrolysis during windlass 

  

operation.

Restriction:

 

200 hours per year(33 minutes per day).

How to eliminate:

insulation of electric motor negative brushes.

ENGINE BANK

Situation:             

critical electrolysis on negative side(red flash).

Cause 1:              

negative wire running from starting battery to 

 

non-insulated engine starter motor.

Repair 1:              

installation of remote solenoid on negative wire 

 

from starting battery to engine starter motor.

After action 1: 

momentary critical electrolysis during engine 

 

start(5 seconds).

Restriction 1:      

200 hours per year(33 minutes per day).

How to eliminate CAUSE of corrosion:

insulation of engine starter motor negative 

 

brushes.

Cause 2:              

non-insulated alternator.

Repair 2:              

replacement of non-insulated alternator by an 

 

insulated model.

After action 2: 

electrolysis eliminated.

Cause 3:              

non-insulated engine sensors and warning 

 

switches.                       

Repair 3:              

replacement of non-insulated engine sensors and

 

warning switches by insulated versions.

After action 3: 

electrolysis eliminated.

Situation:             

Caution status on negative side(yellow led light)

Cause:                  

three stages alternator charger(poor design).

Repair:                 

device removed.

After action:        

electrolysis(very low) eliminated.


HOUSE BANK

Situation:             

critical electrolysis on negative side(red flash).

Cause:                  

Sonar sensor wiring possible poor designed.

Repair:                 

installation of remote switch on negative wire.

After action:        

momentary critical electrolysis during sonar 

 

operation.

Restrictions:         

200 hours per year(33 minutes per day).

How to eliminate:

not defined. Waiting to haul out.

Situation:             

AC current interfering DC circuits.

Cause 1:              

DC charger(poor design/renamed brand).

Repair 1:              

device removed.

After action 1: 

fault eliminated.

Cause 2:              

ultrasonic anti-fouling.

Repair 2:              

device removed.

After action:        

fault eliminated.

Rudder compartment. Faster than usual metal corrosion points. 

After SeaBis installation those corrosion ended. A rust stopper was applied followed by a normal white paint coating and corrosion don’t develop ever since.

Unfortunately, the only camera available for underwater use is a Go Pro hero 2, not made for close shots. The minimal angle of view is 127 degrees with a lot of fish eye effect and to make things worse the water is a bit murky but I decided to attach two shots taken in Tahiti in November 2017 to show the rudder with a complete absence of blisters and anodes not even 5% consumed after almost one year.

SeaBis electrolysis corrosion prevention system and conclusion.

With Seabis installed, it is very easy to identify and repair any electrolysis event. Very detailed instructions available. Mr Glen never takes more than 24 hours to reply to any of my emails. Every potential source of electrolysis must have a single SeaBis Master unit installed – PERMANENTLY!!!!!

After 10 months of using SeaBis Master there are no blisters below waterline, zinc anodes have been consumed at their normal slow speed and some faster than usual above and below deck points of corrosion that I noted before SeaBis now became a very very very slow normal metal corrosion easy to deal with, fix and eliminate.
