Great to see you picked it up..

Please also consider, and I think its very important, to have the boat controlls at the chief.
- rudder hard to port etc
- some speed control, like AK and snail speed..

- dive, periscope depth and surface
Dreaming of...
- dive 20 meters deeper..
- raise 20 meters more..
- surface, AK, blow, all in one command..
- how is your grandmothers cat doing ?
