Good work indeed. Shooting from a boat handheld is a challenge if the waves or wind are significant. I do this routinely with clients and by myself. In the lake country, a boat often is the only way to get the best shot. If the waves are fairly regular in their pattern, it's a lot like riding a horse, adapting yourself to the rocking of the water. But if the waves are disturbed or irregular, it's definitely a crap shoot, and there are many throwaway images. But when the focus locks on right and the IS kicks in and things all fall together, images like these are the result. Good work.
