Now it can be done in houdini, i am very poor with vex and vop.
Maybe some idea…

Thanks in advance

One way to do it would be using a simple particle simulation.

I've attached a hip file that shows this method and uses the particles to displace the ocean surface geometry.

You could also use a greyscale render of the particles as a displacement shader.

have you tried the ripple solver in DOPS? might be a good place to get a general motion going

chopstix thanks for example… I will try

jason|slab i try rippleDop solver, and it has nice resault, i just cheking for some other solution

No problem.

Another thing to note in my example setup is I hard coded the initial velocity so it only works on the X axis.

You can improve the setup by using the ship hulls normals as velocity (just put $NX,$NY,$NZ into velocity in a point sop after you've transfered the N att to the emission curves) This way the wake motion will continue to spread out behind the boat regardless of which direction it is traveling.
