UPGRADING BOAT RENTALS WITH REMOTE ON-BOARD DATA

INTRO

Most small commercial and recreational boats generate large amounts of onboard data, yet very little of it reaches operators on shore. To address this, Teltonika developed a solution that connects to the boat’s network and gathers data from on-board equipment such as engines, wind and depth sensors, and fluid tanks. This allows boat rental managers not only to track a vessel’s position accurately but also to reduce costs related to fuel consumption, manual inspections, and false claims.

CHALLENGE

Operators often have little visibility into what actually happens once a vessel leaves the harbour. Physical inspections, daily walkthroughs, and repeated checks consume significant time, yet none of them show how renters handle a boat in open water.

The consequences are measurable. In the United States, the largest recreational boating market, national coastal guard registered 3,887 accidents in a single year. Sixty-one percent were caused by poor operation, with driver inexperience and inattention among the deadliest factors. Of all technical failures, engine failure alone accounted for 43% of casualties linked to vessel faults.

At the root of this is a data problem. When operators lack reliable insight into real behaviour on the water, the warning signs go unnoticed: engines pushed beyond safe limits, rising fuel consumption, and renters crossing into restricted zones. By the time damage occurs, there is little record of what happened or who is responsible. Disputes are difficult to resolve, and operators are frequently left covering repair costs for damage they cannot prove occurred during the rental. Furthermore, since luxury yachts across Europe rent for €5,000–€20,000 per day, any downtime directly translates into significant missed revenue.

Compounding this is the manual nature of routine maintenance. Fuel levels, fluid tanks, and water supplies are checked by hand and refilled according to fixed schedules rather than actual need. The result is predictable: water runs out mid-trip, waste tanks overflow without warning, and staff spend their day reacting rather than managing. It creates unnecessary workload, avoidable delays, and risks that could be caught earlier with better information.

SOLUTION

All of the information needed to monitor engines, fluid tanks, and other onboard systems already exists within the boat’s backbone. And telematic integrators can monitor this data with Teltonika’s PROFESSIONAL category trackers, FMC650 and FMM650.

What is the backbone?

The backbone is a central cable on a vessel that supplies power and transfers data between all onboard equipment. To allow this network of equipment to communicate seamlessly with each other, it uses NMEA 2000 marine communication standard. This enables multiple engines, monitors, and transducers to share data between each other and function consistently on a boat.

FMC650 tracker is the only Teltonika device that supports NMEA 2000 protocol. It is built to handle the complexity of multiple engines and numerous fuel, fresh water, or wastewater tanks. Depending on the equipment available on the boat, it can also read core parameters such as water depth, wind direction, and wind speed. The device supports data collection from up to 4 engines and up to 16 fluid tanks.

Here is what is possible to achieve with these core parameters:

Fuel and engine insights

Boat operators usually are missing the real picture of which vessels, routes, or skippers are burning more fuel than they should. With NMEA 2000 data, you monitor actual consumption in real time and get alerted to engine anomalies like oil pressure or temperature spikes before they become a breakdown on the water. Factoring in the complexity of managing multiple engines, that can be outboard or inboard, it eliminates the guesswork on which engine needs to be attended to at the repair.

Engine data is especially important for resolving false claims. If someone returns a boat damaged and claims it was like that already, operators have a proof of when vessel systems came under stress. This way, damage disputes and insurance claims are straightforward to resolve.

Fluid tank management

Without monitoring, tanks get emptied or refilled on a schedule, which costs extra resources and manual labour of the staff. Live data from fresh water and waste tanks means pump-outs and refills happen when actually needed, while first-time renters can be automatically notified when fresh water is running low, preventing dangerous situations on board.

Skipper behaviour monitoring

Unlike road vehicles, accelerometer data is unreliable on constantly moving seas, so engine data becomes the key signal for identifying reckless behaviour. This gives operators something concrete to correct bad drivers and reward good ones.

Telling first-time renters that the vessel is tracked is an effective way to deter reckless behaviour before it happens. At the same time, monitoring key trip information such as speed, fluid tank levels, and geozones based on water depth gives the operator a clear understanding of the vessel’s status throughout the journey. This insight supports timely safety interventions and helps refine briefings for future renters.

Talking about safety, reliable connectivity is critical in dangerous situations on the water. The solution can be expanded with satellite communication by adding an Iridium modem connected to the tracker via the RS232 port. This ensures that if renters become lost in open waters, the operator can still obtain accurate vessel location data and send timely rescue.

BENEFITS

• Lower operating costs – correcting renters’ and professional skippers’ driving skills reduces fuel waste and prevents emergency repairs. 

  
  

• Reduce manual labour – switch from daily boat inspections and walkthroughs to accurate data from onboard equipment.

  
  

• Protected seasonal revenue – downtime avoided during the weeks that pay for the year.

  
  

• Reduced liability exposure – evidence of boat's system malfunction or geozones violations helps protect against claims and disputes.

  
  

• Better customer experience – increase revenue through safer trips, proper tank fluid control, and passengers who choose your service again.

  
  

• One operational view – land and water assets managed together, less admin overhead.

  
  

• Get notified of dangerous conditions – protect the vessel and its passengers by monitoring if the water is suddenly too deep, shallow, or wind is up. 

WHY TELTONIKA?

Most telematics integrators treat boat monitoring as a simple moving asset. With Teltonika, operators unlock the full potential of the vessel and gain a much deeper understanding of boat performance.

By choosing FMx650 tracker, you pick a powerful and versatile device that collects essential boat data from on‑board systems. It provides precise location details, engine parameters, fluid tank levels, and information from equipment such as depth and wind transducers. Its support of the NMEA 2000 standard enables operational insights through IO elements and allows seamless integration with any fleet management platform.
