How 2B Sure Works…

The innovative 2B Sure antifouling system works on any hull material and features two electrodes which are suspended just below the waterline, one at the bow and one at the stern. These are connected to a control box, which sends an electrical current to the anodes and releases a limited cloud of copper ions into the water. These do not harm sea life or the environment.

The movement of the ions along the electrical field within the water prevents fouling – the growth of barnacles, mussels and other forms of unwanted organic matter that can seriously affect boat speed, performance and fuel consumption.
