when it comes to logs, there is no such thing as "too much information"
just a few examples:
when GPS fails for whatever reason, you want to be able to go ahead with other means, so log anything that is neccessary to do so. if you go celestial, log every single sight you do, when something looks wrong later on, you can find out where you reduced a sight falsely.
weather? if need be, look it up at the weather services. but it would look better if you could tell from your log if, for example you were out in a certain storm or just on the fringes.
if something breaks, you want to be able to prove to your insurance and maybe the authorities, that the failure is not your fault for lack of maintainance. so write down when and what, also any problems you encountered.
keep a copy where it is save, the original might be on the bottom of the sea when you need it.
and hopefully, you never have to use it to prove your side.
