It is called Propspeed Coverage Calculator and works on smartphones, tablets and computers. The range of antifoulings for propellers and any metal part that lies below the waterline offered by Propspeed is extensive. This configurator makes it possible, in a few simple steps, to figure out what products are needed and in what quantities. It is a service aimed at both shipowners and hull-building yards. Both, in fact, will know exactly what products will be used, giving them the ability to demonstrate what will be done by the yard or to verify the work to the shipowner.
