Angelika,
This system is relatively simple. It is primarily a detection system, which
allows you, the owner to identfy the source of stray currents for
correction. Additionally, it provides a kit to isolate the engine's
connection from the battery to the hull. All of this is a good thing, but
it does not protect and it does not prevent electrical corrosion. It
facilitates YOU to do that.
This subject is extremely complex and cannot be fully addressed in a NG.
There have been numerous books written on this subject if you wish to do the
research. Further complicating this problem is the act of inspecting the
observed corrosion cannot identify the cause of it. As the website states,
the cause could be either galvanic, stray current or both. Prevention must
start at the beginning of construction of the vessel and be continued
through the application of common sense and best practices throughout the
vessel's life-time. Properly executed from the beginning, these practices
will eliminate virtually all corrosion. Please also understand that anode
protection is a band aid, not a cure and consequently, be a CAUSE of
corrosion all on their own.

I recently found out about a new system that prevents boat corrosion.
The system is called SeaBis Electrolysis Corrosion Prevention System.
This system is apparently the first of its kind that detects and
eliminates stray current and actually prevents corrosion. Once the
system is installed and you have completed a process of elimination of
stray current coming from in and outside the boat, the boat is then
protected once and for all. Any new stray current is monitored and
when it turns up it is eliminated and the boat once again is
protected.

The system also comes with an anode voltage tester and prode to
measure the effectiveness of existing anodes. Anode lifespan is
prolonged up to 2 yrs with this system.

Is there anyone out there that has installed this system or has a
better or another way of preventing corrosion damage to boats?
