Where IS the sunken sub at Castaway Cay?

[MrsG]

We plan to snorkle at Castaway Cay and we were wondering, is the sunken sub, etc. in Serenity Bay, or is there another spot to snorkle?

Also, some people mentioned a map of things to see underwater while snorkling. Where do we get one?

Thanks

Mrs G:

It's being discussed in this thread: Castaway Snorkeling Questions

In the Water is my bet

(sorry, could not resist)

The sub is along the snorkling trail along CC Family beach.
