A non-sailing brother in law made that remark while sailing on the Fourth. It's true, especially when you can hardly feel any wind, yet the boat moves in the direction you steer, leaving nothing but a fragile wake behind.
I snuck out on the boat in the morning before the breeze filled in. The bay was flat as a pancake. I only saw this lone boat motor by. I don't blame him, 2 knots isn't going to get you anywhere. You have to be there.
When the breeze got so light my jib collapsed, I had to roll up a few feet to get it re attached to the breeze. Nice morning to be on the water.
