Yes. CleanABoat.com Advanced Antifouling system will work on a balsa cored hull construction provided you remove a small section of the balsa core to expose the outer layer of the hull. As the Ultrasonic Antifouling system needs to be connected directly to the outer skin of the hull for it to be effective. You can carefully cut a section of the inner layer and trim out the balsa core, then re fibreglass the section to seal the balsa core layer and re enforce the outer hull layer. You can then proceed to prepare and mount the transducer on this outer hull layer as per normal instructions.
