We had a boat run up on us 30 miles offshore.We know that he seen us from a distance and figured he would get the number. We kindly asked them to leave, we were anchored and had been on this location for 10-15 mins getting geared up to make the drop. They were total dicks about it, and started circling the boat to zero in on the spot, tossed their anchor and started fishing! they literally backed down 30' from us. We had two guys top side and three going to the bottom. Once I made my decent to the bottom, my dive knife somehow "found" the line that was connected to their anchor, just behind the 15' chain that was connected to the Fortress
needless to say their day was DONE. The anchor was sold with my last boat.
