There was another new wreck that entered the park a year or two before the mystery blue sailboat. Its bow wedged up against the breakwater down near the Suejacq. It gradually was torn to pieces but parts of the sailboat can still be seen on your way out to the bigger wreck, but at deeper depths (60-70 ft). It was another of the infamous derelict boats. I dove on and filmed it shortly after it hit the breakwater.
By the way, the "glassbottom boat" is the Pisces, formerly owned by Lynn Stokes. Lynn and I used to party on it in the early 1970's along with the woman we were both vying for (a Miss Nancy Brantley). He won, but we still had a lot of fun drinking Red mountain and Spinada (all we could afford in those days). I took pictures of the Pisces hitting the breakwater, but lost them years ago.
