Unless you are a Captain-level seaman, I advise avoiding rough waters. Lobstermen and fishermen know how to do it safely, but most recreational boaters do not. It is a skill, or an art. It takes years to get the feel. Besides that, I read that fishermen have the highest fatality rates.
The sea wants to kill you. I believe I have better feel in sail than in power.
