This is great. I love the "working on a boat while sitting in a boat" double whammy. Great color and composition. I really like the reflection as well.
Great...guy busy at his work or fun... the angle without other bouts on left would be welcome but not always possible. For my personal version of photo I would try to blur the reflection in water.
Would have worked better getting up close on the guy building his ship. The reflections are nice but really have nothing to do with the focus of the shot and just distract. nice lighting on his face, looks like there might be something interesting in that model he's concentrating on. Get up there so I can see it better.
