1) Good colour, but as said, the processing in the foreground detracts from the entire photo. A crop just below the yacht could make for a great photo emphasising the sky (IMHO)
2) I like this, really good colour in the surf, and the sky is not overexposed and has a matching tone about it. Waves I think are very difficult to photograph because its very easy to take a boring photo as the wave runs off each end on the photo. good work
