We rented a pontoon boat over the weekend. My sister brought out her sunblock.
Exhibit A: The boat is pointing north, the wind is blowing north to south.
My sister (red dot) was about to spray sunblock. I asked her to go to the back of the boat (green cross) where it wouldn't get on anyone else. She said of course and moved to the back of the boat.
Exhibit B: We turned West. The wind is still blowing north to south. Scenario IF my sister had stayed where she was.
We pointed the boat west. Had she stayed where she was, the people on the port side of the boat would have gotten a face full of sunblock.
Exhibit C Boat pointing west. Wind still blowing north to south. Sister actually moved to the back of the boat.
But since my sister had moved to the stern of the boat, she didn't spray anyone but herself.
Wife: I guess your sister didn't need to move since the wind is blowing from the front of the boat to the back.
Yes, she actually thought the wind would change directions depending on which way the boat was pointed.
