Fleet operations, fully
under control.
Marine Keeper gives charter operators, sailing programs and tour companies a single operational dashboard to manage maintenance schedules, track expenses by vessel, and keep every boat charter-ready.
Maintenance Tracking
Create tasks with due dates or engine-hour intervals, and Marine Keeper handles the rest. Track status across every vessel in your fleet, from zinc replacements to rigging inspections, with automatic reminders so nothing gets missed.
- Dual tracking: engine-hour intervals and calendar-based reminders
- Four built-in views: active tasks, history, hours tracker, and seasonal checklists
- Spreadsheet-style manager with priority levels, cost estimates, and status badges

How engine-hour tracking works
Enter your last service
When did each vessel last get an oil change? Impellers? Zincs? Enter what you know and Marine Keeper starts counting from there.
Log your hours
After each charter or trip, log engine hours. The hour meters go up, and Marine Keeper tracks every engine across the fleet.
Get notified
Island Time is at 100 hours since the last oil change. You get an alert before it becomes a problem, not after.
Do the work, log it
Change the oil, mark it done, the clock resets. Next alert fires when the hours are due again. No forgetting, no guessing.

Financial Planning & Expense Tracking
Running a fleet means tracking expenses across every vessel, every season. Marine Keeper logs every dollar by boat, by category, and by time period. Flag tax-deductible items for your CPA, compare cost-per-vessel to see which boats actually make money, and track year-over-year spending so you spot trends before they become problems.
- Savings goals with compound interest projections for major refits and upgrades
- Budget forecasting and burn rate visibility across your entire operation
- Exportable CSV reports for accountants and tax prep

You're already managing a fleet. The question is how much is falling through the cracks.
Scattered operations
Your maintenance schedule is in a spreadsheet, your receipts are in a shoebox, and maintenance doesn’t happen until something breaks. When something slips, you find out mid-charter.
Compliance exposure
An expired registration or lapsed insurance doesn’t just ground a vessel. It grounds your revenue. And the fine is the least of your problems.
Unplanned expenses
A $30K engine replacement shouldn’t show up as an emergency. But without a financial plan tied to actual engine hours, it always hits during your busiest season.
Your Manuals, Decoded
Upload your engine or equipment manual as a PDF or a photo, and our manual analysis tool helps you identify which tasks to track.
- Scans your PDFs and suggests maintenance intervals for you to review
- Works with any engine or equipment manual: Yanmar, Mercury, Volvo Penta, Lewmar, and more
- Up to 50 GB document storage for manuals, registrations, and insurance
