Okay - I DID IT!!! FINALLY, FER CRYIN' OUT LOUD!
I now have the heave-to maneuver under my belt. It was easy, now that I'm following proper instructions.
It was crazy windy, overcast, and rough out today on Pensacola Bay, so 'twas perfect for practicing.
Didn't have time to practice MOB cuz it just got way too gnarly and had to motor back in by 2:00pm.
Thanks to everyone who cleared things up for me.
