You might think of creating a terrain wake for the water at the shp's front[prow?..I live in the prairies remember] and giving it a that foamy water texture, forget it's name, falling off by slope and height to the water texture you're using...just a thought...great image already btw...gonna be a good un when you're done.. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
