Ohhhhh, pretty (rubbish with no maps)!!!

I took the liberty of trying a mist effect, kind of an after math look is what I was trying to achieve, on one of the ships. Looks OK, could do with some tinkering, but at least it gives a view as to what could be achieved. I apologise for the back ground but I had no other options from what WAS on my computer.

I think with sea, and a better environment map that the top effect may be the best. It looks like puffs of smoke.
