Resident Marine Life

This is a well-established wreck site and there is an abundance of marine life that resides in the area. It is common to see large schools of small and medium tropical fish, stingrays large and small, eels, lobsters and the occasional Turtle or Eagle Ray.This is also an excellent location for spear fishing and hunting.


The tug was originally named the Mary St. Phillips and although there is not a lot of information currently on its past we know that it eventually ended up in South Florida as part of the Broward County artificial reef program. The o was sunk on May 1, 1993 alongside the mariner to barge which was also sunk simultaneously on the same day. The nice part about the location of these two Wreck is that on the right day you can swim between the two of them on a single dive.
