I my self do not use a stringer I use a goodie bag they know something is there just not where it is and as for the boat anchor next time wrap the line around the barge this way they spen a hole lot of time and energy trying to unhook it or you should have brought it up with you and asked if they wanted to buy an anchor and i to came face to face with a jew fish/golith but cause i had the bag he did not know where to get the fish and he fallowed me every where i went on that dive . well good luck in diving and spearfishing
