What it does
Every system. Every interval. One log.
Meet Finn
Ask anything. Get a real answer.
Finn is your First Mate — an AI that reasons from an expansive library of authoritative publications covering marine diesel, electrical, rigging, and more, then cross-references that reasoning with your actual equipment manuals. Every answer comes with a citation and a confidence score. If Finn can't figure it out, he'll tell you.
Your manuals
Upload your boat's documentation
Add your engine manuals, systems guides, and builder specs. Finn reads them and factors your exact equipment into every answer — not generic advice for a boat like yours, but advice for your boat.

Maintenance log
Log a service as easy as texting a friend
Just tell Finn what you did — "changed the oil, 412 hours" — and he'll log it correctly, with the right timestamp, engine hours, and task category. No forms, no dropdowns. A complete, timestamped history that travels with the boat and hands cleanly to a new owner at resale.

Reminders
Alerts before things go overdue
Set intervals by hours or calendar. Finn tracks your running hours and surfaces reminders before a service window closes — not after.

Protect your investment
A log that pays off at the dock.
Buyers pay more for boats they can trust. A complete, timestamped service history — every oil change, every haulout, every part replaced — gives a prospective owner confidence that nothing was skipped. First Mate makes that record effortless to build and easy to share.
- Every service entry is timestamped and tied to engine hours
- Export a clean PDF summary to share with buyers or surveyors
- Proves no intervals were missed — the record speaks for itself
