I like the colors and the silhouette in the first, but the third is the most eye-catching because of its perspective.
I think I'd like the 2nd better if the boats were both silhouettes, but also the prow of the boat on the right is sticking into a busy reflection, which breaks its clean lines.
It might even be worth a look as a vertical, with the left boat as the foreground.
And as much as I like the 3rd one, IMO cropping it right below the reflection of the tree stump makes it more engaging.
