Try diving or snorkeling some alternate sites when you are weathered-out from the main shipwreck sites, of if you would just like to see something new.  These sites are not as impressive as the main sites but are noteworthy just the same.  I will add GPS coordinates as I re-locate and document these sites.  Coordinates marked with * are transcribed from my old charts as accurately as possible but may be off by a few hundred feet.  If you know of other sites that you would be willing to share email me at
