Cheers for the replies so far. I think, except for experience, the term ability would be a catch all trait that includes the others. Maybe if experience could be defined in more detail.
I know of some folks with thousands and thousands of miles and/or a high level of certification that I would not trust as a skipper or crew of a boat while I know people who I would trust almost immediately even with a minimum of experience.
I have read about 'bumfuzzle' and they were derided for not being experienced enough. Obviously they had the ability but not experience. However they now probably have more experience then most of the naysayers.
