the sea gives but sometimes takes, it can curl itself around a passerby, an innocent fisherman on the rocks, a woman, a man a child. it can come from nowhere, rise like a mighty hand and swipe you from existence. to read the sea you must know it, have it within your soul, for the sea can be a mysterious environment to decipher, many layers in contradiction. 
the sea commands respect, and respect is attention  ones senses must be in tune with the moon, and the ocean will know, it has unfathomable wisdom.
