Creating Boat Wake

I am working on adding realism to the boat system for my game. I need to add wake and have been researching different ideas to make it look more realistic. One of my main problems was I couldn’t find proper decals to use for the beam which is the wake. Then I found this post, which mastered exactly what I am doing (except their water causes too much contrast with the wake but anyways…). Does anyone have a texture that looks like or similar to that for me to use for the beam, or better yet does anyone know of a system that is already done? I tried looking through some free models but they just use some crappy particle emitters which works but doesn’t look as cool.

I’m not sure if I’m allowed to give off-site links but simply do a web search for “Free Video Game Textures” or similar. There’s a huge selection of assets available.
