This is very much a work in progress

The boat needs a mast and rigging, a sailor and a wake!!

The foam on the wave crests is difficult! i'm still working on it any help
would be gratefully received.

    That is some rough sailing ahead. Fantastic surface features.

   I just had a though you might try for the foam. Take a duplicate of the
 image you are using for the HF. In a paint program try to add some black
 noise to the image. Keep the noise at a reasonably small scale and spread
 it about randomly. Now save this second image to be used as a second HF
 object. Give it the exact same scale as the first but use a very high water
 level on the second HF.
   This will if successful create a HF like the first but only the crests
 of the HF will show since the bottom portion will be removed by the water
 level setting. The black noise I suggested is to create tiny holes in the
 remainder of the HF to help give it that foamy look. You might even add
 some white noise along with the black to get some high and low areas that
 are different from the height values in the first HF. You may need to combine
 the two HF's inside a merge statement so they integrate together seemlessly.
 Otherwise with a clear medium you would see obvious artifacts from the over
 lapping areas.

  Will it work ? Beats me but it's your time and you might just get lucky.
  If it does let me know so I can try it.

Good Idea Ken I'll let you know if it works.

Nah, forget the mast and rigging...go for that Winslow Homer painting.  Put
some poor dude in the boat, and have a ship and a hurricane looking thing in
the background.

Hmm... If you have the superpatch (and haven't already thought of this) I'd
suggest using slope-dependent textures for the foam.
OR, if you're a masochist, and again, in possession of the superpatch, you
might develop an algorithm for sampling the HF and creating appropriate
media containers in appropriate places... Nah. Forget it. Too far-fetched.

It looks like ice maybe you need to soften or smooth it out so it's not so
rough. Maybe add a glass texture to it I don't know. I'm just learning 3D but
been doing 2D art for a long time. Just my opinion though.
