Buying a new-to-you boat often results in being POed when repairing something. PO stands for Previous Owner. He's that dumb SOB that did that dumb thing that made your repair take way too f'ing long.
I was told a pretty funny story about being POed. A guy bought a boat and found that the anchor light at the top of the mast wasn't working. He made the trip up the mast where he found the wires corroded and, most disturbingly, found that the wiring to the anchor light was done with speaker wire! This inspired much colorful language about the mental capacity of the PO that he yelled down to his wife who was on deck. After a short while, the PO's wife came over and let them know that they had bought a new boat and it was located on the next pier over!

Difference between a power boater and a sailor out on the water: A power boater is going some place special, a sailor is already there.
