Designer of the SeaBis System. Glen Bishop.

Dedicated to preventing the ONLY cause for electrolysis corrosion – stray current. Permanently.

SeaBis Designer Glen Bishop.

Stray current is the only thing that causes corrosion from electrolysis. You can prevent this completely with the SeaBis Master System. It will last forever. Get an 8-year guarantee for the equipment’s operation and warranty for preventing stray current, plus support for free. Email for more information.

Capability Statement.

With more than 2,000 SeaBis Master Systems in continuous use, we guarantee and warranty the SeaBis Master System will 100% prevent the cause of electrolysis corrosion. How to Prevent Corrosion instructions must be complied with.  We know such causes as moisture, damage, carbon build up and new equipment will cause new corrosion so provide a minimum of 8 years diagnostic support.

Glen Bishop’s qualifications are two degrees in marine electronics engineering.  Specialising in corrosion prevention. Corrosion cause prevention practice from year 1968 with complete success from 2003.

SeaBis Master System is proven 100% reliable in excess of 20 years in continuous use.  There is a good reason we guarantee and warranty for 8-years.  That reason is that we are 100% correct. Prevent the stray current, then you prevent the ONLY CAUSE of electrolysis corrosion.  Permanently.

Glen Bishop’s background:

55 years in corrosion prevention, solely and in great depth. Including 9 years at sea, the last 4.5 in submarine service. 

Formal training:

5 years at HMS Collingwood, Portsmouth, England. 

Informal training:

8 hours every week for 45 years studying how to prevent corrosion using MPLab, Protel, Multism, Excel and 223 test vessels. Circuit construction and proving in 5 large ponds. Testing and improvement on all 223 vessels over 10 years.  Then commercial. 


Corrosion prevention, over 55 years. After 2003 as commercial with total success. 

Commencing with inspiration:

I was the Surveyor for every Class Society (insurance authority) World-wide. During Surveys, I saw most ships with corrosion –  stray current corrosion damage, Normally in the hull adjacent to DC power generation area. I was privy to Class Societies records and knew over 800 ships per year were severely damaged with high proportion sinking. Then in 1992, my own vessel became porous over a 3-week period in a new mooring with a steel post into the Earth between each vessel. In 21 days, my boat became porous! The same week, two tugs became porous. 10 years later and AU$500,000 and 223 vessels, I had the answer and went commercial. 


Glen has never sold any to ships, but a large number are in use in domestic and commercial vessels. Shipping companies insure their own hulls thru self funded insurance and get a new ship and crew in one phone call to a Third World country. The boat or yacht owner is biased – he does NOT want to risk drowning and has control. 

The Beginning:

During a cold winter’s day, in 1992 Glen was asked to attend a tug that had returned from refit 3 months earlier. The crew had opened the bow buoyancy tank and found corrosion – thousands of needle shaped holes all just below of the water surface caused by current. Using a digital micrometer, he measured hole depths of 4 mm. The hull was 5 mm thick. Back to dry dock and new bow plates. The tug was out of service for five days, so that alone cost $150,000. We had not developed our system at that time, consumed all 5 days at the Tug and could not find the cause. The first instrument was developed. It measured nine amps of electric current thru the hull, then promptly incinerated itself. Many versions later, How to Prevent Corrosion, became viable. 

The Growing Years:

We installed prototype instruments in a total of 223 vessels. Eventually, we faced the fact that normal technology would not survive when connected to metal that was in contact with the water. So we swallowed very hard and accepted the fact that only very sophisticated protection and a microprocessor would probably service. They did so in all 223 vessels. How to Stop Corrosion, became effective. 

Where we are going:

We have installed in excess of 2,000 Master Systems. The Master has proved itself totally reliable. We are expanding World-wide. SeaBis Master System is guaranteed for 8 years. With a design life of 20 years. 


Corrosion has many names:  galvanic, boat, yacht or marina corrosion, bonding or rust. They are all caused by electric current dissolving your metal to the Earth.

We consider imparting knowledge of how to stop corrosion to be our primary objective. We offer free training and diagnostic support by Marine Electronics Engineer with two degrees and a life lime defeating corrosion.

N.B. Anodes and antifouling are still required, but can now work correctly with a vastly increased life expectancy. SeaBis stops the CAUSE of corrosion – stray current.
