Well we just recently purchased a moomba and we noticed several scratches on the back of the boat where you would put your wakeboard on. This is probably due to the fact we have a black bottomed boat so we found a way to prevent the boat from being scratched all to pieces in the back. Place some type of pad back there so your wakeboard, surfboard, etc. hits that instead of your boat. Here's 2 pictures of what we put back there and it's done a good job staying in place and doesn't look bad at all. Almost looks factory made.
