My sons gave me a logbook when we bought our CD-22. Since I don't have hour meters I figured it would be a good way to keep track of hours for oil changes and other maintenance. As I got into the routine of using it I found myself recording river depths, weather conditions, passenger names, wildlife seen, ocean going vessels sighted, and any number of things that happened on my cruises (165 since buying the boat in Dec 2002). More recently I have been using copied log pages (the original log has long since been retired) and inserting them in a three ring binder that also holds the technical manuals for the boat, motors and other equipment. I never have been much of a diarist or log keeper but I have surprised myself with how I've kept my 'log' up to date. From time to time I reread some of the early entries and realize the central fact of my C-Dory existence: I had absolutely no idea when I bought my boat how much I would enjoy owning it. Contrary to the old saw, the day I have to sell it will not be a good day.
