Looking for a casual game on the high seas!

Ok. So maybe I've just been watching too much one piece but I would really like a game where your main mode of transportation is a ship. Newer(metal) or older(wooden) is fine but I think a proper wooden sail boat is preferred. I played sea of thieves a long time ago and like it but it lacked any form of customization and honestly should revisit.

Hard no's: mandatory PvP. Attack/defend centric gameplay

Most preferred: relaxing and exploring, some combat fine just don't want it to be the center piece.

Thank you in advance for any suggestions!
