Sorry, I'm slow these days...
different backgrounds to compare against (because greys are tricky)
How it looks small, compared to existing patches:
I tried to keep the shapes very simple, but they can be dumbed down even more. I re-used the deck color to emphasize explosions inside the splashes...
Overall I took the same idea but made it one ship manuvering hard, and the wake of the ship as it splashes left then right radically forms the yin-yang division down the center... It's a looser demarcation now, but I think it works. Individual "lines" of white thread would be the white caps on the waves showing the violence of the manuvers.
