How it works
Your boat. Your history. Your assistant.
First Mate puts three things in one place: an AI that knows your boat, a log that remembers everything, and weather when you need it.
01 — Ask Finn
Get answers from an AI that's read the manuals
Finn is First Mate's AI assistant — trained on 47 authoritative marine publications and cross-referenced with equipment manuals. Ask it anything: why the engine is running rough, what the service interval is on your raw-water impeller, or how to trace an electrical fault. Finn cites its sources and tells you when it's uncertain.
Finn discloses confidence levels on every answer. If it doesn't know, it says so — and tells you where to look.
02 — Log trips and repairs
Keep a record that actually follows your boat
Tell Finn what you did in plain language and it logs it for you. Replaced the zincs, changed the oil, fixed a leaking through-hull — just describe it and First Mate creates a timestamped entry tied to your boat. Your full service history is always one tap away.
Your log travels with your boat, not your phone. Every entry is searchable, exportable, and ready to share with a surveyor or buyer.
03 — Check the weather
Conditions at your marina, before you leave the dock
First Mate surfaces marine weather for your location — wind, sea state, and forecast — so you can make a go/no-go call without switching apps. Ask Finn whether conditions are suitable for your planned trip and it'll give you a straight answer.
Weather is built into the conversation. Ask Finn about conditions the same way you'd ask about anything else.
