X-craft
You are correct, we are not shooting bb's. We are shooting 3-16" and 1-4" ball bearings. The "scarring" you see are all holes in the hull. We have three people in Wisconsin that fight boats. You may be able to get help there if you feel the need to build big, and then decide there is a need to enter into combat.
