If you get in the area, take the tour of the boat. Very interesting! According to the tour guide, they added about 100' to the hull with a fake extension, and also built a fake sail to cover up the real one.
The real sail is one of the most interesting pieces of submarine construction I've seen. The entire forward part of the sail rotates 180 degrees to bring the fire control radar into use, and then rotate sback to streamline and protect it. Very, very cool, and would make an awesome R/C subject!
Underwater, the ONLY way to fly!
