You see in England where they had a bunch washing up to shore and they were trying to keep the people from taking the stuff form them?? I say: Good for them! Take the stuff. Next time try a little harder to keep that crap on your boat!! I know the guys that do this for a living are serious about safety and keeping the containers... but I bet they could come up with a better system if it was really important to them.
PS Kacper - I have NEVER seen one. I even mentioned in a thread a long time back whether anyone had seen one and I don't think anyone on this forum had... not floating, anyway. Besides, I understand that even the floating ones sit just under the water surface, so you pretty much have to hit it to know its there (which, there in lies the problem).
