hey puk... remember that :) the Jetski demo in DB...
the water was one of the few things i liked about the old DB...
i even played with doin my own sub sim in it...

... until i found out how slow it rendered.
(old sub model running in DB Jetski seas )Nice start 'Pete... take a quick look at these pics
( bottom one in Blitz made ocean, Titanic model the work of Guillaume Darier ) ...
ideally you'd want your water to be a lil dynamic (move a lil)... to simulate some wave action...

see how the water seems to undulate near the ship instead of being a flat plane like surface... although i may have made these waves a lil too big (wide) and might need to scale em down a bit...
anyway... i can send you some code if you wanna look at it... stuff i hacked and moded from somone elses example :)
i like naval sims... i hope you continue through with this...
