Hmmm. I'm not sure that adding stealth to the hull of a private yacht is 
necessarily a very wise 'improvement'. I think flourescent Green with bright 
Orange stripes might give you a higher survival rating on the open ocean 
:-)

No I hadn't noticed till you pointed it out. The camera is very close into 
the yacht at that point in time and there are lots of artificial lights 
around, so my brain just accepted that a light shining on the roof suddenly 
went out.

I think this is down to having very fine, but well defined lines (a big 
color difference) viewed from a changing camera position. There is a name 
for this, but I can't for the life of me think of it. If this is the reason 
there are some things you can do with anti-aliasing and jitter to reduce 
such effects, but these have quite detrimental render-time overheads. 
Alternatively, at this resolution you can't really see the wood-grain effect 
anyway, so you might consider using a far simpler pattern for the animated 
renders.

Eriban posted a thread entitled 'Rock The Boat (Final)' on 10th July this 
year on povray.binaries.images. The Wake is discussed in that thread and 
there's a reference to the source in povray.binaries.scene-files. I didn't 
try it myself, so I don't know how well it would animate and I don't know 
how easy it might be to combine with your heightfield techniques.
