Illustration Friday 'Ocean'

I really wanted to create something brand new for this weeks Illustration Friday topic of 'Ocean' but I just haven't managed to fit it in. I have lots of ocean themed images in my archives so I've dug this one out instead. 

It was originally created for a children's magic painting book. I'm not quite sure what a dog and a cat are doing in a boat in the middle of the ocean but they seem to be having a nice time. Maybe the cat is hoping to do some fishing?
