AI crew for cruising sailboats
A crew that never goes off watch.
Sailwatch is building the intelligent crew for cruising sailboats. One watches the water ahead, one knows every port ashore, and one looks after everything aboard.
Three apps. One crew.
Each does a job a good crew member does. Use one on its own, or let all three share what they know about your boat.
Ahead
Spots fishing gear and floating hazards ahead, and tells you in time to steer clear.
Explore Ahead
Ashore
Finds tonight's anchorage and your next port, with the rules, costs and local knowledge that fit your boat.
Explore Ashore
Aboard
Tracks everything aboard, keeps maintenance on schedule, and gets the right part to your next port.
Explore AboardThe next ten years at sea look different.
Cruising has changed less in thirty years than almost any other way of travelling. Charts went digital and weather went online. The rest still runs on tired eyes, dog-eared pilot books and a locker full of spares.
We think every boat will soon keep a lookout that never blinks. Local knowledge will be waiting in the next port before you arrive, specific to your boat, dated and sourced. A breakdown will mean a delivery, not a lost week. Couples and solo sailors will go further, because the routine watching is shared.
The skipper stays in command. The sea stays the sea. We build the crew that makes sure nothing important goes unnoticed.

Built aboard a Bali 5.2.
Every feature is designed and tested at sea aboard our Bali 5.2 test catamaran, by people who live the problems we solve. In 2026 she spent 90 days testing and collecting data from La Rochelle, around Iberia, to the Mediterranean. This is the view from her deck.
One boat. One crew.
Tell Sailwatch about your boat once. Every app knows her draft, her route and what's aboard, so each one gives answers that fit.
One boat profile
Length, beam, draft, engines and crew, entered once.
One route
Where you're going shapes every alert, stop and delivery.
One equipment list
What's aboard, what's due and what fits.
