Tracking
How to track rental boats: trackers, phones and fleet platforms compared
Every rental operator wants the same four answers: where each boat is, whether it will be back on time, whether it is inside the rental area, and what shape it is in. Here is what each kind of tracking can and cannot tell you.
Updated · 7 min read
There are three common ways to keep track of rental boats: a standalone GPS tracker, a phone or tablet left aboard, and a fleet platform that reads the boat's own instruments. They differ less in the map they show than in what they know about the boat and the rental, and in how much work they leave for your dock staff.
1. Standalone GPS trackers
A self-contained tracker with its own cellular connection, either battery powered or wired to the boat. Many are built for cars, trailers and equipment and sold with a simple map and geofence alerts.
- Quick to fit and inexpensive per boat.
- Position and a boundary alert, usually nothing else: no engine hours, fuel or battery.
- Battery models trade report rate for battery life, so a moving rental may update only every few minutes.
- The tracker does not know the rental: it cannot tell you a boat is overdue, only where it is.
2. A phone or tablet left aboard
Some booking apps track rentals through a device that goes out with the boat. There is no hardware to install, but the tracking is only as reliable as the device: it has to be aboard, charged, switched on and out of the customer's pocket.
- No installation, and the app often already knows the booking.
- Gaps when the battery runs down, the app is closed or the device is left on the dock.
- No readings from the engine, tanks or batteries.
- A device to charge, clean and replace for every boat.
3. A fleet platform on the boat's own network
Most modern boats already carry an NMEA 2000 network that links the chartplotter, the depth sounder and, through the maker's gateway, the engines. A unit on that network reports what the boat itself knows: position and speed, but also engine hours, coolant temperature, oil pressure, fuel level and battery voltage. A fleet platform puts those readings next to the rental, so it can say not only where the boat is but whether it is late and whether it is fit for the next customer.
- Overdue alerts tied to each due-back time, not just a map.
- Engine hours that count service intervals down by themselves.
- Fuel, battery and engine alarms before the boat is handed to the next customer.
- An installation per boat, and boats without a network report position and battery only.
How they compare
| Question | GPS tracker | Phone aboard | Fleet platform |
|---|---|---|---|
| Where is the boat? | Yes | When the device is on | Yes |
| Is the rental overdue? | No | Often, from the booking | Yes, from the booking |
| Has it left the rental area? | Yes | Sometimes | Yes, with a buffer and escalation |
| Engine hours and alarms | No | No | Yes, from the engine |
| Fuel and battery | No | No | Yes, where the boat measures them |
| What happened on the trip | A track | A track, with gaps | Track, speed, engine and alerts |
What to ask before you choose
- How often does a boat report while under way, and while at the dock?
- What happens out of cell coverage: is the trip stored and filled in later, or lost?
- Does the screen show how old each reading is, so a silent boat is not mistaken for a stopped one?
- Are alerts tied to each rental, with a grace period and an escalation you can set?
- Can it read engine hours, fuel and battery on your boats, and say plainly when a boat cannot measure something?
- How much power does the unit draw from the house battery while the boat sits?
- Who sees the data, and can you export your trip history?
