I was following the attached tutorial that used a boat facing a specific direction, but when I placed the boat and rotated it, the boat reset its rotation back to its starting rotation after dismounting. I then also tested this without the alignment and it seemed to work the same way.

Steps to recreate:
Follow the YouTube tutorial up until the point of rotating the boat.
Attached is a video of me experiencing the specific bug. Excuse the low frame rate - I'm working from a bad laptop and the recorder is not helping.
This bug has been experienced on both 1.19.4 and 1.20.
Your game is modified in the video. Please reproduce the behavior in vanilla, and update the issue accordingly. 🙂
