I am re-doing a 1993 Champion and I want to cover up the bow, under the trolling motor, with a thin rubber sheet so that it isn't slippery. Does anyone have any idea where to get a thin material like this? Would prefer it to have the "bumps" to help with the non slip. I have found some rolls of a material for over $100 but all I need is about 3'x4' piece or so, something I can cut to match the shape of the very front of the bow. Any help would be greatly appreciated.
