Hi Carl Björndal,
Here is a rough sketch. You might take it apart and configure it more to your liking of course.
The two Formula Effectors are the main part. Wave and Flag are more tiny supporters here.
The idea, if I understood the simulation correctly, the ship creates a main wave, along the axis of moment, and an ripple like arrow, based on interference of the lateral and the transversal wake, based on the forward movement and the ship shapes, pushing water to the side. My understanding of interference is, that there are two frequencies out of sync. so they produce more details. Perhaps more like harmonics. Either way, I guess the way to go is based on at least two deformer.
I have attached two more files, perhaps in each is a little bit of a solution or at least an idea to push it further.
Please let me know if there is any question. BTW, the 360 in the effector formula, can be increased or decreased for extreme speed up adjustments, then use the t slider for the fine tuning.
All the best

Alternative, with a helix as falloff:

Option two, just falloff waves

Sorry—I have obviously problems to upload files here at the moment.
