When it blows,
how noisy
the mountain wind!
but when it blows not,
where will it have gone?
Zen Waka
In my dream I saw two boats on the nearby shore
Exposed breasts are very important on a mermaid. A topless woman was the only thing I've ever read from old sailing superstition that could cause perfect winds at sea. There were many rituals that could cause more wind, like whistling or scratching the back stay, but they could go too far and bring on a storm so were considered bad luck. But a exposed breast was always associated with perfect winds. That's why sailing ships had bare breasted figureheads.
Good to know!
