Jesus Walking on Water: Interpretation Needed

I love this rendition of Jesus walking on water. This piece is just begging to be interpreted.  I see several nuances, but most interested in how Jesus seems not to be looking at the boat.  And is that Peter? Are those even the disciples? Are is that just a yacht on a pleasure cruise that Jesus is totally ignoring? Thoughts?
