Thank you for those images Neal and Jim

Notice that the bottom part of the rudder is not the same size as the top part ...

yet the size of the rudder on the bottom does not extend beyond the bottom of the hull either, which would be the case if the rudder was of the same size as the top one.

What is that shroud around the prop for? I've noticed it on USN Virginia class and Russian submarines also.

Does it have anything to do with cavitation?
