Nice serene scenes, Jon. I would crop about half the foreground from each image. The water is fairly plain and there is more interest in the clouds.
I prefer the 2nd shot for its compositional elements, but the top of the posts at the end of the jetty are lost in the background. They need to be separated. I realise that might not have been possible unless you could move to higher ground or grow a few feet taller.
Nice shots.
