Built to beat a soggy paper logbook.

Most boat maintenance lives in a binder in a damp locker, a stack of receipts in a glove box, or a spreadsheet that nobody touches between seasons. Boat Journal is the real-software version, designed for the way boats actually age.

How Boat Journal stacks up.

How is Boat Journal different from a cloud app like YachtWave?

YachtWave is free, AI-powered, and cloud-based. Boat Journal is $20 one-time, runs entirely on your machine, and never sends your records anywhere. If you prefer your maintenance history not be a data product, the local file is the safer default.

How is it different from a subscription like My Vessel Logs?

My Vessel Logs is around $59 per year with cloud sync and USCG-compliance exports. Boat Journal is $20 once, with no recurring fee and no cloud. The tradeoff is no real-time sync. The win is your records still work when the subscription would have lapsed.

Who Boat Journal is for.

This is for you if:

  • You own one boat that you plan to sell well in a few years, or you own several across categories (outboard, inboard, jet ski, tender).
  • You are restoring a project boat and want a paper trail buyers will pay for.
  • You have been bitten by a subscription app that lost your data when you stopped paying.
  • You want maintenance records that outlast the company that built them.

What you get for twenty dollars.

01

Every vessel in one file

Outboards, inboards, sailboats, jet skis, tenders. Each gets its own service history, engine hours, photos, and reminders. Switch between them with one click.

02

Engine hours, not miles

Marine engines age on hours and seasons, not odometers. Boat Journal tracks both and reminds you on whichever comes first. Twin engines log independently.

03

Haul-out and bottom paint history

Every haul-out, every blister repair, every bottom-paint application, every zinc swap. Five years of records ready when the broker asks, the surveyor inspects, or the next owner walks the dock.

04

Survey-ready report

When it is time to sell, generate a polished PDF with every service, every haul-out, every receipt. Brokers and surveyors move faster when the paper trail is real. Hand it to a buyer at the dock.

05

Winterization checklists

Lay-up, fogging, antifreeze, fuel stabilizer, battery pull. Reusable checklists per vessel, checked off and dated each season. Spring commissioning the same way.

06

One price, lifetime updates

Twenty dollars, one time. Every V1 purchase includes free lifetime updates: new features, new vessel templates, every future release. No subscription, no upsell, no premium tier.

The report a surveyor or buyer actually reads.

Selling a boat is the moment your maintenance history pays off. The survey-ready report turns every log entry, every haul-out, every impeller swap, every zinc, into a polished PDF with a cover photo, a vessel summary, service history grouped by year, photo gallery, and totals. Hand it to a broker, attach it to a Yachtworld listing, or hand it directly to a buyer at the dock. The records do the selling.

Reminders that watch your engine hours.

Marine intervals are hours-based for some services, calendar-based for others, and both at once for the items you cannot afford to miss. Boat Journal computes reminders from your actual log entries, not from a generic OEM schedule. Twin engines reminded independently. Overdue, due soon, and upcoming grouped at a glance.

Your data lives on your computer.

Boat Journal runs entirely in your browser. No server, no account, no telemetry. When you add a vessel, log a haul-out, or attach a photo, the data is written to your browser's local database. We cannot see it. We do not have it.

The backup file is a plain JSON file you save to a folder of your choosing: Dropbox, iCloud Drive, an external drive, your boat's thumbdrive in the chart-plotter mount. Restoring on a new computer is one click. The file is human-readable so you can verify your records before you trust the app.

Frequently asked questions.

Does it handle twin outboards or twin inboards?

+

Yes. Each engine is logged separately with its own hour reading and service intervals, but rolls up under one vessel. You see port and starboard side-by-side or you collapse to vessel totals.

Does it track sailboats too?

+

Yes. Sailboats have an auxiliary engine, rigging service intervals, sail inventory, and haul-out history. All are first-class entries in Boat Journal.

Does it work offline?

+

Yes. Boat Journal is a single HTML file. After download, it runs entirely in your browser with no internet required. Useful when you are at the dock and cell coverage is spotty.

Where is my data stored?

+

In your browser's local storage on the device you opened the file with. There is no server. Export to JSON to back up or move between devices.

Do I need an account?

+

No. There is no sign-up, no login, no email collected at runtime. The only place we know about you is the checkout receipt.

Will I get future updates?

+

Yes. Buy once, every future version is free. Re-download the latest file from the receipt link anytime.

Can I use it on multiple devices?

+

Yes. The license is per person, not per device. Use the JSON export to sync your data between machines.

Will it generate a USCG-compliant log?

+

Boat Journal logs the same data a surveyor or insurer would want, but it does not produce a specific USCG-formatted document. If documented compliance is a hard requirement, look at My Vessel Logs.

What about voyage and crew logging?

+

Boat Journal is a maintenance log, not a voyage log. Track services, engine hours, haul-outs, and survey prep. For underway logs, trip reports, and crew certifications, a dedicated logbook app fits better.

Why a one-time price instead of subscription?

+

Because a maintenance log is the kind of thing you should still own twenty years from now, when the company that built it might not exist. Subscriptions diverge the company's interests from yours. We chose the side you would choose.

Is there a free trial?

+

Not currently. The product is twenty dollars with a 14-day refund window. Effectively a buy-and-try with the money back if you do not keep it.
