Sea, water, or wide open space has that calming effect, so they say 🙂  It must be true. When you look out to the sea, you somehow feel at peace.
“In still moments by the sea life seems large-drawn and simple. It is there we can see into ourselves.”  – Rolf Edberg
The sea is everything. It covers seven tenths of the terrestrial globe. Its breath is pure and healthy. It is an immense desert, where man is never lonely, for he feels life stirring on all sides. Â –Â Jules Verne
Land is the secure ground of home, the sea is like life, the outside, the unknown.  Stephen Gardiner 
I was on a ferry ride yesterday, yes at sea, it was a bit choppy.  An hour or so after reaching the shore, it rained cats and dogs, thank goodness, for just a while!- moi
