Boat wake for waving water?

Hello ~

My name is Shin. I'm trying to implement Boat wake for waving water now. But i don't know what is a common way for it. I searched all threads related with Boat wake in forums. They say following three method

1. Particle system

2. Decal texture

3. Use Projector

What is a common way to make boat wake for waving water? How do you implement a boat wake for water? I already applied particle system but it was not simple for waving water. And i also tried to get the example code from the forums. But most download link is unavailable. If you have good examples for this, please let me know the download link or share for me...
