The company said the Boat Sure device is easy to install, attaching to the hull with no skin fitting or dry docking required.

Sure Systems said Boat Sure uses a boat's hull as an amplifier and emits inaudible ultrasonic sound waves that remove and prevent the growth of algae and bio-film, which barnacles, molluscs, sea pocks and the like adhere to.

Without algae and bio-film, there is no surface to adhere to and no food source for the abovementioned animals. So they simply fall way, searching elsewhere for nourishment.

Sure Systems said Boat Sure offers a wide range of benefits, such as: no more antifouling while the unit is operating; a reduction in drag which maximises fuel economy and boat speed; cost effectiveness by reducing down-time and maintenance; 100 per cent eco-friendliness, causing no harm to marine or aquatic life; and, promoting cleaner, safer waterways.

Sure Systems says it offers solutions for all water-based applications where algae, pathogens and bio-film accumulate, including marinas, lakes, ponds, pools, cooling towers, and cooling intakes.
