The world is round... so you have to use spherical projection.

That's great!  Wonderful job!  You've got a very detailed and believable sense of realism.

It looks like the angle of the wake varies (gets smaller towards the back). A wake always has an angle of about 39 degrees.

How do you measure and verify something like that? Thanks for the randomly useful information...

I remembered it from when I was playing with water scene's in 3DS. There's been studies about that that. Verifying it wouldn't be too hard at an aquatics lab (where they test ship models etc). I do remember seeing alot of discussion involving a duck's wake so searching on that should yield some results.

This could also be adapted to do some nice coastal renders with wave refraction/ diffraction
here's some linky's.

All of this stuff would be useful in a 'Water Physics' plugin...

after much rendering here it is 1.2mb so it might take a while to load about 50-60hrs render 6 (600x600) squares

i moved the position of the ketch, and added in my wake texture after figuring out how to move textures around:D:D

Nice job.  Unfortunately I can't really see the wake very well, and the water is slightly randomized in each section.

nice one... That shore looks an awful lot like your sailing into Queenstown :-)

Queenstown New Zealand?... would be great to do some renders of that type of landscape

just thought this would be interesting to post, it is the stitched image that the pano is made from 2400x1200

Nice job.  This looks really realistic - when I first saw that I thought "those are cool clouds, I wonder where he took that photo?"
