Suction Dredge "Culebra" at Naos Island.  I have dug many good bottles right on this beach.  Through the years, many bottles were thrown overboard while ships were at dock or anchored here.  I found the remains of a old wooden ship during a minus tide one day.  The old wood had copper sheeting nailed to it with old square copper nails.  There is lots of good stuff still here just waiting to be found.  I never went back out there after the Panama Defense Forces took over the causeway.  I hope to return there again one day to look for bottles and relics.
