Choose Boat Journal if you have more than one vessel, you sell vessels every few years and want a polished history to hand a buyer, or you want trends and reminders the math handles for you.
Choose a paper logbook if you keep one boat for decades, you prefer the ritual of writing entries by hand, or you mistrust software for record-keeping that has to outlast any company.
If you keep one boat for thirty years and never sell it, a paper logbook is perfect. If you have multiple vessels, sell every few years, or want trends and search across decades of records, software earns its twenty dollars.
Plenty of captains do. Keep the paper book on the boat for at-the-dock entries. Type entries into Boat Journal weekly so you have the report and the search. Treat the paper as the underway log and the file as the maintenance ledger.
Export the JSON backup periodically and email it to yourself. The file is a few hundred kilobytes and can be restored on any machine in a few seconds.
A polished printable PDF with a cover photo, vessel summary, service timeline, photos, and totals. A buyer or surveyor reads it in five minutes and asks better questions afterward.
Some captains do. The tactile habit is part of the appeal. Boat Journal does not replicate that. It replaces the math and the resale documentation, not the ritual.
