FOR fleet operators

THREE CHALLENGES EVERY
OPERATOR FACES.

Whether you manage five boats or five hundred, the challenges are often the same.
01

LIMITED VISIBILITY
ACROSS THE FLEET

Managing multiple vessels often means relying on manual inspections and phone calls.
WITH Sentinel
Monitor every vessel in real time with live status, alerts, location tracking, and fleet-wide visibility.
02

DOWNTIME
COSTS MONEY

Unexpected onboard issues can quickly impact availability and revenue.
WITH Sentinel
Monitor critical systems remotely and identify problems before they disrupt operations.
03

MAINTENANCE GETS OVERLOOKED

Tracking maintenance, inspections, and service history across multiple vessels is time-consuming.
WITH Sentinel
Manage maintenance records, inspections, service history, and vessel documentation in one place—keeping your fleet organized and charter-ready.
GUEST EXPERIENCE

GIVE EVERY GUEST A BETTER EXPERIENCE.

Guest Access gives charter guests visibility, convenience, and useful information through the Sentinel app.

TESTIMONIALS

TRUSTED BY THE PEOPLE WHO MANAGE BOATS EVERY DAY

Sentinel's system helped us save the lives of nine guests aboard one of our rental boats.

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.

When we notice a drop in battery capacity, we replace it before our guests even notice.

Our experience with the Sentinel device has made it much easier for us to monitor the boat and make proactive decisions.
