Sailing to serenity

What is the antonym to freaque wave? Serenity may be!

I came across this article entitled "Sailing to serenity" by a writer named Jack Branswell with the byline "Boat trips in Australia's Whitsunday Islands offer unspoiled beauty, quiet and peace." As one who just came back from a trip to Australia, the article certainly attracts my attention.

This is how the article started:

"Ralph Waldo Emerson once said, "Nothing can bring you peace but yourself." That may well be true, but a few days at sea sleeping under the stars with nothing but the gentle rocking of a boat as you fade into slumber, sure helps you chart your course toward peace.

"Here I was aboard the Enid, a sailboat anchored off a tiny island in Australia's Whitsunday Islands, about 500 kilometres south of Cairns on the east coast. It was 2 a.m., no lights other than from the moon, and no sounds other than the waves and a zephyr, a soft gentle breeze, reaching the furled sails."

It's basically an article in the travel section with many pictures. Here is probably the sail boat in which the author and his wife spent time on:
But I certainly have no desire to be on something like this following kind of sail stuff:
On the other hand what I would truly enjoy is to be walking on a beach like this one:
where you can look back and see your own foot prints. Yes, we can do similar thing in Michigan when there's a sheet of new snow in winter. Of course it's not the same. Take an early morning walk on a beach like this and watching and hearing waves gently roaring toward you -- that's what dreams and poetry are made of. But while watching the waves rushing toward the shore, beware the freaque waves! There is always a freaque wave beneath there somewhere, some time, somehow.
