Ensenada Honda is about 4.6 square miles in area,[REF] but with a maximum depth of 40 1/2 foot, it is the second deepest bay in Puerto Rico after San Juan Bay [REF].
Inside the harbor, there are depths of 5 to 7 fathoms outside of the shore bank, which as defined by the 3-fathom curve, stretches unevenly up to 3/4 mile offshore from the northwestern side of the harbor.
