This tugboat was recently sunk off Nassau and was named the "Blue Plunder" through a contest to name the wreck. A fairly new wreck, it's just starting to become encrusted with life and attracting fish and animals to the site.
Historically, sharks left the area when scuba divers entered the water. The bubbles from the regulators scare them off. Since shark dives started in the Bahamas many of the sharks have lost their fear of these bubbles.
