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.
