The "ess" shape of the wake suggests a very easy-going ride for the passengers of this ship. Easy does it, relax and enjoy, as every cruise should be. Having grown up with a boating family, I can tell you that cruising is rarely this effortless.
Wonderful in its simplicity. You use scale incongruity here to compliment the curving wake -- the s-curve floats within a sea of calm. Normally, centered subjects are static. In this case, the scale incongruity is heightened by the centering. I love it -- Yessss!
