USING SENTINEL
From morning coffee
to evening anchor.
Before
you arrive.
Check status, warm the cabin, get the boat ready — from the car, from home, from anywhere.

When you're
onboard.
Auto-logged trips, smart maintenance, digital documents. Sentinel works quietly so you can fully arrive.

After
your trip.
Anchor watch, geofence alerts, service reminders. Sentinel keeps watch while you’re away.

TRUSTED BY THE PEOPLE WHO MANAGE BOATS EVERY DAY
As Yachtcharter Huibers, we are extremely satisfied with Sentinel. Three years ago, Sentinel’s system helped us save the lives of nine guests aboard one of our rental boats. These guests had used an electric grill several times while the boat was off the shore power, which later caused a short circuit in the batteries. When they reconnected to shore power, the batteries began emitting toxic hydrogen sulfide gas. Thanks to Sentinel, we noticed this in time and could immediately instruct the guests to leave the boat. Had they gone to sleep, they would not have survived – we are sure of that. Sentinel is truly an invaluable asset for any yacht rental business.

Our experience with the Sentinel device has made it much easier for us to monitor the boat and make proactive decisions. For example, when we notice a drop in battery capacity, we can order and replace it before our guests even notice, preventing any potential complaints. I would also like to thank Ivan for his excellent service and support. Our experience with Sentinel devices has truly enhanced the quality of our business, and our guests can feel the difference as well. Many thanks, on behalf of Kek Yachting.
