YachtBot, the AI host

Say it, and it's logged.

Say it or type it: a trip, a service, today's engine hours. Each comes back as a card. You confirm, it writes. It never saves anything on its own.

Log a trip, with stops, hours and fuel
Record a service or add a maintenance item
Record engine hours and tell you what's due

YachtBot plan, $24.99 a month or $249 a year, and includes everything in Plus. The log itself stays free. How we use AI

Better than a spreadsheet or a paper log.

It's at the helm.

The log is on the phone you already carry, so the entry gets made at the dock, not next week.

Hours and dates set what's due.

Maintenance comes due by engine hours or by date. The app shows what's coming due.

Yours to keep.

Your records are never locked behind a subscription. If a plan lapses, everything stays readable and exportable.

Share the boat? Add partners when you're ready.

The Plus plan ($9.99 a month or $99.99 a year, first month free) brings your partners in: who has the boat each week, messages, issue reports and trip costs, on the same log you already keep. Each partner installs the app on their own phone.

App Store reviews

Owners say it works.

4.5 on the App Store, from 8 ratings.

“Boat Partner has made the management of our shared boat so much easier. From scheduling to coordinating has been so much more effective. Everything is one place and made our shared ownership much more simple and organized.”

Paul & Stacey — “Game Changer”, App Store review

“As owner in a boat partnership, the biggest headaches are usually scheduling related and communicating with your fellow owners. This app puts everyone on the same page! Calendar with ability to make changes included. Messaging center to discuss the beautiful water or a maintenance issue. Highly recommend your group all join!”

Jimmyde19 — “Great way to communicate”, App Store review

“I wasn't sure what I'd get but this app delivers exactly what I needed and I didn't even know I wanted! It's very clear it was designed by people who understand what a boat partnership needs. So much time saved! I used to hate having to keep track of engine hours and other boat details. The log book was always missing something. With the app it's all there and really easy to update.”

MikekiMikekiMikekiM — “Real time saver!”, App Store review

“We use this to run our four member partnership on a 40ft sea ray. Helps keep all the communication, calendar, and fuel info in one place. Lots of features, and can download your data and take it with you.”
