About Sentinel
Freedom on the water.
Confidence onboard.
Connected boat technology since 2015
OUR MISSION is
TO HELP PEOPLE STAY CONNECTED TO WHAT MATTERS MOST ON THE WATER.
We think boating should feel simpler, safer, and more enjoyable. So we make connected boating something any owner can rely on — clear information, real confidence, and peace of mind, on any boat, anywhere in the world.
Our story
More than a decade of connected boating
Boating should be about freedom and time well spent on the water — not wondering what's happening onboard while you're away. That's why we built Sentinel.
Sentinel keeps boat owners, fleets, service companies, and builders in touch with their vessels through one connected system of hardware, software, and cloud. It turns what's happening onboard into something you can see and act on — so you make better decisions, catch problems early, and stay at ease wherever you are.
The team
BUILT BY MARINE AND TECHNOLOGY EXPERTS.
Boating should be about freedom and time well spent on the water — not wondering what's happening onboard while you're away. That's why we built Sentinel.
We pair deep roots in the OEM marine industry with serious engineering and a clear read on where boating is heading. That mix is what lets us build connected technology that holds up at sea — not just in the lab.

WHY WE BUILT SENTINEL
Boating should be about freedom, adventure, and enjoying time on the water — not wondering what’s happening onboard when you’re away.
More than a decade ago, that simple belief became the foundation of Sentinel.
What started as a vision to make boat ownership easier has evolved into a connected ecosystem trusted by boat owners, builders, fleets, and marine professionals around the world.
Helping people spend less time worrying about their boats and more time enjoying them.
