KnownWaters
Now piloting

The knowledge platform every yacht should have

Capture, organise, and retain what your crew knows

KnownWaters is a private knowledge platform built for your yacht. The important details the crew has already discovered, kept in one place instead of being scattered across different sources and never seen again.

Now available to a limited number of yachts for pilot. Get in touch to get started.
Find out what it's costing you
The problem, and the fix

The knowledge is already there. It's just not staying anywhere.

Right now

Knowledge lives in one person's head

Buried in old WhatsApp threads

Crew leaves, and the knowledge leaves with them

Same reccies, done again and again

No way to know what's actually trustworthy

With KnownWaters

A shared record that stays behind

One searchable place, always up to date

Every season adds to what the boat knows

Verified knowledge, ready before you arrive

Reviewed and verified by the bridge team

What's included

Built by crew, for crew. Every feature exists because a real deck or bridge team needed it.

Interactive Knowledge Map

Every anchorage, tender drop, beach, restaurant, and supplier your crew has found, pinned, searchable, and browsable at a glance.

Voice & photo capture

Log knowledge in seconds by voice note or photo, right from the deck. No forms to fill out later when you've already forgotten the details.

Reviewed & verified

Every submission goes through your bridge team before it's live, so what's on the map is knowledge the whole crew can actually trust.

Nearby Knowledge

Arrive at any anchorage and immediately see what your own crew has already logged close by. No digging required.

Sea Log

A private, exportable record of what you've personally contributed, portable with you if you move to another vessel.

Log knowledge via WhatsApp

Send a voice note or photo the same way you already talk to your crew. It lands straight in the review queue.
