This is pretty cool! I'm the developer of a semi-automatic electronic logbook system for sailboats: https://bergie.iki.fi/blog/electronic-logbook/

Right now I'm using YAML for the file format, as I wanted something that would be reasonably readable for both humans and machines. Markwhen would also fit the bill nicely, so that's something to consider, at least as an export format. My entries have a lot of properties, though (stuff like wind speed, vessel coordinates, barometer, etc). Traditional ship's logbooks were done in a tabular manner to record all this. So I'm not sure if that would end up looking quite messy. Here is an example of a day of log entries in the current format: https://github.com/meri-imperiumi/log/blob/main/_data/logboo...

I'm using these also for some data analysis, like watermaker membrane health, or sailed miles per crew member.
