New to the board, first post, so : Hello World!
Interesting idea. I presume the added predictors of rudder control would then be boat movement (mainly as a surrogate for wave data) and wind. I would investigate it with a more frequentist approach at first. Identify any regularities that could be used either as global parameters or within small (<1s) timeframes (or both).
After a very quick look at NOAA for possible databases to exploit, it seems that the archived data is in fact pre-processed and not raw, with waves averaged over a period of 20 minutes. See:
https://www.ndbc.noaa.gov/rsa.shtml
This is unusable for the present purpose. On a side note, their approach to pre-processing wave data could be worthwhile to look at:

The crux of it seemingly a Fourier transform. I might have sourced some real time marine wind data. Waiting for an answer.
The best would be to have data (all of it, including output to rudder control) logged by Pypilot at a high sampling rate in a variety of sea conditions.
