Sometimes, it really does help to be composing in a particular format.
My panasonic LX3 has a “16×9” mode that gives me this panoramic look. Even though I know I can take the regular, full frame and crop it, looking at the screen while in 16×9 makes you see things differently, I think.
In this case, I could feel the symmetry of the mountains on either side with the boat in the middle much better, I think, than if I had a much more square frame and just tried to visualize.
This was taken while sitting on Bophut Beach on Koh Samui, in Thailand.
Plus the panoramic mode really emphasizes the horizontal lines in the photo. Love how you placed the earth/sky line so low. Really gives a sense of the expanse!
