That paint works particularly good if you let your boat roll around in the surf for awhile....Surprisingly clean for having been at sea that long..... can we get that paint?
Presumably the anchor concrete stayed put, it was the chain that broke!!
This sure looks like a Hazard to Shipping that should have been secured and removed long before it beached itself after 2 years!! Who would want to hit one of these in the dark??
Perhaps you have never done an overnight run???
