Quite Blue? Quite Tranquil? Quite Quiet? Your title as a fill in the blank, right? Sorry, enough foolishness. I really like the image. The subdued tones work really well for me.
hmm, i love the texture in the sky, but cropping a bit more out might have made the veiwer focus more on the boat. i also might have pumped up the yellow a tad, to make it pop. lovely scene here, you captured it quite well
