I believe "C" is the smart option. No use beating yourself up and the boat today when tomorrow could be a whole different game. I subscribe to the theory that I am a recreational sailor and do not have to be anywhere in particular at any specific time. This means I can pick and choose when the boat moves. I have done my share of slogging against wind and current for endless hours to reach a not so far destination and learned from it that it is just a waste of time with no benefits. Right now I will turn around and sit at a marina or an anchorage or leave the boat until conditions improve.
