The SeaBis System will protect your vessel from all this corrosion.

Each photograph is a thumbnail, mouse click will change page to a larger image with text explanation.
The cause is detailed by each photograph. In every case the SeaBis System will eliminate the stray current.

FACT: When there is no stray current there can be no electrolysis corrosion. Guaranteed by SeaBis.


The stray current flows, boat to boat to mooring via water and seabed for more than 100 meters in fresh or salt water. This is easy to prove using SeaBis and a probe.

The causes are always eliminated by the SeaBis System. It is critical to check with all equipment fully operational. The reason is most electrics and electronics only fully power up when in complete use.

The symptoms vary but the cause is always the same: stray current.
If you have any doubt email Contact SeaBis a photograph and we will respond.
