A spreadsheet is free, customizable, and what most owners actually use today. Boat Journal is structured software that does the math and produces a polished report. Here is the tradeoff.
$20 lifetime · Works offline · No account · Lifetime updates included
A maintenance spreadsheet is a grid of cells you set up once and edit forever. Boat Journal is structured software that enforces the schema, computes the trends, and hands you a printable report at sale time.
A direct comparison across pricing, storage, platforms, multi-vehicle support, account requirements, offline behavior, and updates.
| Feature | Boat Journal | a maintenance spreadsheet |
|---|---|---|
| Pricing | $20 one-time, lifetime updates | Free (Google Sheets) or a one-time office license |

| Survey-ready report | Printable PDF generated from your data | You design the print layout yourself |
| Backup | JSON export, copy the file anywhere | Cloud-tied (Sheets) or a file you copy manually (Excel) |
| Maintenance burden | None. The schema is the product. | You maintain the spreadsheet structure as the boat grows |
Choose Boat Journal if you would rather spend the twenty dollars than maintain the spreadsheet schema yourself, you want a report that looks polished without designing it, or you have more than one vessel and your tabs are starting to multiply.
Choose a spreadsheet if you have already built one that works, you need custom columns that do not fit a maintenance schema, or you want cloud sync via Google Sheets for free.
Probably not. If your sheet works, you have already done the hardest part. Boat Journal is for owners who keep meaning to set one up and never finish, or who have outgrown a sheet across multiple vessels.
Not directly. You would enter the active vessels and recent services by hand on first run. Most owners do this once over a quiet evening and move on.
No. Boat Journal is desktop-first and stores data on your machine. If real-time cloud sync to a phone is non-negotiable, a Google Sheet is the better fit.
You can build a print layout in a spreadsheet, but it is hours of work and the result is awkward. Boat Journal produces a polished PDF from the same data with no design effort.
Compare it to the time you have spent maintaining columns, splitting tabs per vessel, or reformatting for the next service. Twenty dollars is one half-hour of a marine mechanic's labor.
