SeaBis Master System 8-year money-back guarantee, warranty and diagnostic support,
8-year free guarantee, warranty and (link) diagnosis support with SeaBis Master System: We will either prevent all the stray current that is the ONLY CAUSE of marine electrolysis corrosion or pay you back your purchase cost of SeaBis Master less non-recoverable expenses. How to Prevent Corrosion must be complied with. Guarantee here.
Prevent the only cause: marine stray current. Permanently with SeaBis Master System. Guaranteed.
Marine stray current is always caused by the vessel experiencing the corrosion.
Proof, DC (battery power) causes the stray current that is 100% cause marine electrolysis corrosion: Wikipedia electrolysis.
First paragraph: “electrolysis is a technique that uses direct electric current (DC)”
Proof, real-life photographic and Testimonials with humour follow. SeaBis Master System prevents 100% of the stray current that is the ONLY CAUSE of 97% of ALL corrosion. Permanently.
The remaining 3% is caused by galvanic (different metals in very near proximity). It is easily prevented AFTER stray current is prevented. We will guide you.
Before and after real life proof SeaBis Master System prevents All causes of marine electrolysis corrosion:
Utopiall on the slip before SeaBis System. Followed by after SeaBis System, submerged for 12 months.
Before SeaBis System. Utopiall with hull coating bubbles. Cause: the Hull is dissolved by stray current.
Utopiall. SeaBis Master System installed, under-water view, submerged for a year, no bubbles or growth. *** Antifouling works as designed ***.

Glen Bishop: I am an ex-submariner. So know Kiwi Birds (extinct Engine Artificers) (oil can merchants) well.
I have recently had the pleasure to use one of your units and would like to congratulate you on a fine product!
Being a fellow retired submariner, I hope you will understand when I explain that I borrowed the unit from a fellow yachtie, Nick Walker whom you were able to help and speaks highly of your unit. Also, as an ex-Chief ERA on O Boats (Glen Bishop – I thought Kiwi Birds are extinct?), you will naturally understand it doesn’t come easy to ask a “Greenie” (Electrical – skilled therefore superior) for help.
Our yacht recently sailed from Fremantle to Bali and back via the Indonesian Archipelago and the Kimberly. We encountered some wet conditions which at times resembled ‘diving now, diving now’.
With a strong suspicion that we had some stray electrical currents with wet nav lights etc, I would have usually spent weeks taking fittings apart to find the cause. Your unit allowed the faults to be readily isolated (12 in all, with some very minor that would have been very difficult to find normally). By the end of a few days of working through the problems I have a balanced electrical system, albeit I completely isolated the engine circuit as per your suggestion.
Well done and good that you could commercialize your naval experience.
I also enjoyed your boat humor so to close on a lighter note…………………………..

Glen Bishop: Peter is the first to admit he had very little electrical knowledge and communication via satellite while at sea was difficult. However, we succeeded and eliminated all causes.
I have a live on-board steel hull yacht with very expensive corrosion. The SeaBis alarms Critical.
Glen Bishop: I am glad you are using SeaBis, not a multi-meter. The cause of corrosion is specific electrical current and multi-meters cannot measure it. They will only confuse you.
I have completed the changes and testing of my electrical system. There are 2 systems: Engine and house.
When I attach the SeaBis to the positive and negative of the house bank and the green/yellow to the hull, the SeaBis reads Caution on the negative side. This is a remarkable result from before.
Caution means that there is a very small corroding current which I will attempt to track down in due course but I can live with this now. It means that the severe corrosion will now cease. There is a small fault in the negative side of the house circuit.
Please comment on the above.
Glen Bishop: All fixed Peter. The Caution is just that Caution. It will wait until you are ready.

You are welcome to use my testimonial with verification. We have spent the past few days isolating quite a number of issues. We have fixed these and now got the SeaBis unit to a “normal” state on the house bank with the engine disconnected from the battery bank and the engine battery isolator turned off.
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, it’s been A1 service.
Email/s not received. I will phone. Test emails OK so email me direct at Glen Bishop
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
Hi Mike, the causes were typical. Keep SeaBis turned on as they will re-occur – carbon build up and moisture. Glen Bishop.

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 led into an investigation, this in turn lead me to the SeaBis. I completed How to Prevent Corrosion and time has proven the cause is removed. No more stray current corrosion.
Glen Bishop: Hi Paul,
This problem is very common, not just on Dutch barges but on nearly all vessels. The exception is professional fishermen with generations of experience. They have learnt the hard way. The SeaBis System eliminates the cause. That is why we provide a money back 8-year guarantee – it has never been claimed.
I have a cruising catamaran and need corrosion cause elimination to both propellers. They are less than 4 months old and severely weakened by corrosion – I think electrolysis. The hull is fibre glass so why? I attach a picture. This is costing me a fortune so please help. Does SeaBis fix the cause? John.
Glen Bishop: Hi John,
You are correct, the propellers damage is electrolysis. In a metal hull the hull would be damaged. As it is fibre glass the stray current is concentrated into the propellers. The SeaBis System will eliminate the cause.
John: 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.
Corrosion, hundreds of rusted pits covering steel hull. I would buy the whole system if I could speak with someone on how to use it or install it. I think I understand the concept. My concern is that our steel hull is 65 feet long and the metal corrosion is taking place mainly toward the bow area. our batteries are at the stern. My question is will the third wire read problems that far away? I’m being told the electrical current is coming from the shore with current in the water?.
From Glen Bishop: We communicated by e-mail and Skype video. Steve has a Paddle Wheel Steamer is now completing the final stage of eliminating all corrosion. Yes, the third wire senses corrosive current and will read up to 2 kilo meters. Yes, contact to other than absolutely dry soil or water will complete a circuit to the Earth and cause your batteries, if connected in non-to dissolve all metal. Steve’s Paddle Wheel Steamer now complies. Insurance is effective.
I am going through prop anodes on my steel sailing yacht about every 6 weeks, so have a problem. I have 4 independent battery banks, 1 diesel main engine with 2 alternators. A generator with its own alternator. I use an inverter charger from my domestic battery bank. My 12 volt system is an insulated return system. My problems have started since we fitted a new generator and water maker. Could you recommend which SeaBis system I should install. Many thanks.
From Glen Bishop: Terry opted to purchase one Flexible SeaBis System. With How To Stop Corrosion, moving one SeaBis many times, was lengthy Terry eliminated all the causes.
