Fronts, Fire Alarms, and Coffee

In an attempt to fly in front of a cold front headed our way we left our mooring early. Before coffee.
Within 5 minutes of our departure the fire alarm was sounding on board. I had left the oil cap off the engine and exhaust was filling the cabin. Shut down. Problem quickly fixed.
Within the next 5 minutes a strange rattle was emanating from the engine room. Sailors get to know the sounds of their engines and this was not right. Shut down. Rag wrapped around prop shaft. Problem quickly fixed.
Here's what I've learned.
Coffee first, then start your day.
