I appreciate all the support! Actually, by the time I got back to my boat, put my engine back down and untied, one of the other boats was done and the angry guy used their ramp. All said and done, he waited an extra 60 seconds. His drama was not at all warranted. But I don't want to be too hard on him. Everyone has a bad day from time to time. Maybe the poor guy was triggered by my "Gulf of America" T-shirt.
It's all good because it made me think about that "rule." It's a good and necessary rule - but as Juls said, only when the marina is crowded.
