Be water, my friend...

Hi all.
When I expected, the water is going to convert it to me into a nightmare....
In this case I've downloaded a sail boat from 3d Google warehouse.
With reference to the sea, I've put two surfaces. The first one, at the bottom, with blue color. For the second one, at "sea level" I've find (material section of this forum) a "water pack" (slightly modified) an I used it
Finally, with PS I've added "moon reflect" and a red light, wich is compulsory when sailing at dark conditions. Really, in this part of the sea, I should put a "tri-color light" (red on port side, green at starboard and white on backward).
I've read the Patrick Nieborg ( also know as Patricks) text about "Kerkythea Material Editor". It helps me a lot, but due to that text is wrote over an old version, I've found several problems using "trasnmittance" in order to "masking" the bulb on keel. For now I've passed PS....
So, PSE C&C
Thanks again, and I apologize for my (bad) english

It's a nice image, obk!
I think that you will have to work more with the water to be more realistic.
Create the sea as a closed box with water material on top, and black or sea blue on the sides and bottom. Make sure the top face it pointing up to the sky.
