to clarify, nolatom, I my question was; as the two of us learn to sail together, how will we determine which of us is "skipper?"
There are definitely some good suggestions/models set out here - enough to make us think how we'll work together on board. So thanks, everyone.
And if all else fails? One should simply threaten to hide knives or mess up the toolbox! Muwahahaha. (Dang, I learn fast!)
