Hi Hugh. I like the new pictures. That's a beautiful sub. Good luck on the re-fit.
    As for dive planes, I've always thought that unlike a surface boat, a submarine should have a kinda "fish" shape. The big Nuke subs are something like a whale and it's the most efficient shape.
    If you look at most fish they have little fins about midway down their bodies and they rotate the leading edges of those little fins much like we do with the dive planes on our boats. The big subs have them on the sail like you said to counteract the snap roll thing.
Some subs have dive planes in the back to act I assume like the tail on a whale. I know that's not very scientific but it's an observation.
