I have written a plain-language guide about following seas, surfing, broaching, bow-bury, pooping waves and pitchpole risk.
It is not meant as a finished authority. I would really like feedback from sailors with offshore or heavy-weather experience: what is wrong, what is missing, and what should be explained better?

The guide is also background for a small autopilot/sensor project I am building, but this page is mainly seamanship-first.
Stay safe
