How Do We Do It?
The SeaBis System uses a microprocessor (very small computer) to identify the causes then Process of Elimination instructions, make all wet fittings electrically open circuit. In Home terms we pull the electrical plug out of the socket. Now no stray current can flow so no electrolysis. Your vessel and equipment are immune. For the SeaBis System Guarantee click here.

How Do I Use SeaBis?
SeaBis is a tool to identify the causes of stray current that creates electrolysis corrosion. Once identified, Process of Elimination instructions, supplied with SeaBis complete the process. Where engine / equipment hours are less than 200 per year, the Easier Method can be used. Otherwise use the Full Isolation Method.

Proof... photographs
After 14 years of development and trials on over 200 vessels, we confidently guarantee the SeaBis System will protect your vessel and equipment from the stray current that causes electrolysis corrosion. Try the SeaBis System for one year (time to prove the SeaBis System works), complete our Process of Elimination instructions, and if you have any doubt contact us. We will resolve that doubt or refund the purchase price of SeaBis Stray Current Detector. For proof of our statements click here.
Myths and Worst Practices ...
Some people pay to slip and repair their vessels twice before the fitting SeaBis System. Read on to avoid unnecessary expense and heartache. Click here.
Is My Engine Electrically Isolated ...
Larger professional vessels, tugs and wellheads use electrically isolated engines by standard design. Unfortunately most domestic vessels do not use isolated engines. To tell if yours is look at the starter motor. If there are two thick 10 millimeter wires from the battery to the starter motor, it is probably isolated. Use the SeaBis Pro kits. If there is one 10 mm wire then the engine can not be isolated. Use the SeaBis *DIY kits.
Why Not Cancel Out The Stray Current?
I deliberately chose not to attempt to cancel out the corrosive current by applying a reversed current, as the cause, commonly, is two or more sources in parallel. One would negate the reversed current of the other. In addition the stray current changes with water flow past the hull, so with every tide, whenever the vessel or any vessel within 100 meters moves. Elimination of the cause/s always works.
