This is actually a second shore-dive at the Portsmouth Olympic Harbour, located at the corner of the government dock near the Coast Guard station. Follow the line out to the anchors (dive 1) and then follow a second line to the Stacked hulls. About 600 ft (185m) out you run into the stacked hulls and will be treated to a excellent site. There's not a lot left but if you can get out to the lake and need a dive, well, here you go. There are two hulls to look at and some fish also. This is a long swim so watch your air. While visiting the site, remember that this is near a residential neighborhood, so keep it clean and quiet.
