"The fishermen know that the sea is dangerous and the storm terrible, but they have never found these dangers sufficient reason for remaining ashore.” — Vincent Van Gogh
Fishermen and sailors know the dangers of the sea. For a sailor it would be as foolish to not sail as to not drive a car. Sure these are calm waters in the picture but that's the trick of the ocean, to entice you out. A sailor knows how to navigate any waters knowing they often change with little warning. Either way the delight of flying sail in the wind makes all else pass away.
