This is a very interesting discussion. Keeping the original vessel's mission straight in the mind keeps misunderstandings to a minimum.

There is (at least) one point that I am still confused about. Was the standard operating procedure to steer with the front rudder or is this the result of on the water trial and error? (like kangaroo hopping became the preferred mode of biped locomotion on the moon) It looks a bit funny to see in the last BD video the steerman grab the front steering wheel to steer with his arms reaching over the back steering wheel that remains fixed. Was this by design?
