Here's the one I've used since I bought the boat in 2008:
The Evergreen Pacific Log Book
Yep, that's the same one I referred to that we use. Those were not big enough to hold all our running logs, so we ended up having a few different style logs for that as well both because of gifts or not finding the Evergreen wherever we were at the time. But we kept all the maintenance and fuel logs in the Evergreens, which didn't mind being in the ER or utility/generator room at all.
