Know exactly what every charter really earns.
Track revenue, costs, client value, catch history, maintenance, and profit velocity in one captain-first operating system.
You run the boat. You still don't run the numbers.
Charter captains lose profitability to invisible costs and forgotten clients. CaptainOS makes both visible.
Trip P&L lives in your head
You know gross revenue. You don't know what the trip actually cleared after fuel, bait, ice, and the mate.
Your best clients get forgotten
Repeat customers, their species, their tackle preferences — all locked in text threads and paper notes.
Spreadsheets don't scale a season
Booking calendars, expense sheets, catch logs, invoice trackers — none of them talk to each other.
One operating system, five captain-first modules.
Each module works on its own — together they turn every trip into a data point that pays.
Charter Log
Every trip captured in under a minute: boat, type, party size, revenue, and every cost line.
Financial Dashboard
Net revenue, margin, booking-source ROI, and monthly close — computed, not typed.
Client Memory
Lifetime value, trip history, preferences, and notes that carry across seasons.
Catch Log
Species, quantities, and hot-spot patterns tied to the trips that produced them.
Maintenance Log
Engine hours, service intervals, and expense history per boat — no more surprise haul-outs.
Log the trip. See the truth.
No consultants. No spreadsheets. Setup takes under ten minutes.

See what you actually made
Net per trip, margin per booking source, and lifetime value per client — the numbers that matter.
A dashboard your accountant will actually respect.

Every client, every trip, every preference — remembered.
Repeat customers are the margin. CaptainOS keeps them in sight so your best anglers keep coming back.
- Lifetime value per client
- Species and tackle preferences
- Repeat-visit patterns and cadence
- Notes that stay with the client, not the crew
Know the fish. Know the boat. Know the schedule.

- Species trends by season and location
- Engine hours logged automatically per trip
- Service interval alerts before you're overdue
- Cost history per boat, per system
