Hi all!
I have already post a reply in the thread of nefeladamon's excellent tutorial.
Basically I prefer joegrundman's method to nefeladamon's when near the enemy coast because in enemy controlled airspace, surfacing might be unwise. Because I found some points a little confusing, I rewrote joegrundman's original guide.
Comments very much welcome!
