5 STEPS TO IMPROVE BOAT MANAGEMENT

Vehicle telematics service providers have to navigate a saturated market and compete for each new customer. But what if we told you that there are plenty more fish in the sea? With more than 32 million registered motorised boats worldwide and a handful of specialised solutions, recreational boat tracking offers a clear growth opportunity for telematics companies. Many boats are already connected, yet most operators still lack the fleet insights needed to improve utilisation and increase profitability.

So which insights actually matter? Below, we outline the five key challenges boat rental operators and fleet managers face every day, along with the data and solutions you can build to address them.

WHAT IS SMART BOATING?

Smart boating is an approach for marine fleet management that prioritises data generated by the boat’s on‑board systems. Instead of relying on manual inspections and guesswork, marine GPS devices are used to support informed decisions about maintenance, operation, and skipper sailing skills.

Its popularity began to grow with the introduction of the NMEA 2000 standard. To put simply, it is a communication protocol for marine equipment – such as sensors and navigation screens – that allows electronic devices to operate seamlessly on board and support safer sailing.

HOW TO START WITH SMART BOATING

To start building smart boating solutions, you need two things: a tracker that can read NMEA 2000 data, and a fleet management platform.

For professional marine management, Teltonika offers FMC650 and FMM650 trackers, both of supporting the NMEA 2000 protocol. These devices connect directly to the boat’s central cable and transmit all relevant data to a fleet management platform of your choice.

With the hardware in place, we can understand which data points matter most to your customers and how they translate into real operational value.

#1 MONITOR FRESH AND WASTE WATER TANKS

Daily boat operations involve managing multiple fluid tanks at the same time, each with a different purpose and risk profile:

Manually checking these tanks is time‑consuming and prone to error. More importantly, mistakes at sea have serious consequences. Running out of fresh water can quickly become a safety issue, while an overflowing black water tank often leads to regulatory penalties.

For example, the EU Directive on Port Reception Facilities prohibits sewage discharge in marine protected areas. Fines vary by country, but in Baltic Sea waters, illegal sewage discharge can reach €2,000 to €10,000 for recreational vessels, and significantly higher for commercial operators.

The challenge is compounded by renter behaviour.

Renters are often unaware that fresh water is finite or that the black water tank has a limited capacity. Even when operators provide a thorough briefing, there is no guarantee that renters will act on this information during the voyage.

How can operators manage a boat’s tank levels more reliably?

Remote tank level monitoring provides a practical answer. For instance, FMx650 trackers can monitor fluid levels in up to 16 fluid tanks. This allows operators on shore to track levels in real time, send proactive alerts to renters before a tank runs out or overflows, and even help plan routes based on remaining capacity.

#2 EVALUATE DRIVERS WITH ENGINE AND FUEL DATA

Boat operators usually miss the real picture of which vessels, routes, or skippers are burning more fuel than they should.

With NMEA 2000 data, fleet managers can 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.

Why can’t operators just rely on the accelerometer data?

Accelerometer is a part of the tracker that registers changes in motion. It works well on land because most movement comes from the vehicle itself, such as acceleration, braking, and cornering. That makes it easy to distinguish “normal” vs. “reckless” driving patterns from the sensor data.

At sea, that assumption breaks down.

A vessel is always moving due to external forces like waves, swell, wind, and currents. These forces continuously produce acceleration in multiple directions (heave, pitch, roll, surge, sway, yaw), even when the vessel is operating normally.

As a result:

• The accelerometer cannot reliably separate intentional manoeuvres from wave-induced motion.

• Rough sea conditions can generate acceleration patterns that look aggressive even when the operator is behaving safely.

• The same driving behaviour can produce completely different sensor readings depending on sea state.

Because of this noise, accelerometer data loses its diagnostic value for behaviour analysis.

Engine data, on the other hand, is directly tied to operator input and vessel performance, not environmental motion.

Signals like RPM spikes, rapid throttle changes, engine load variations, and fuel consumption anomalies reflect what the operator is actually doing, regardless of wave conditions.

That’s why engine data becomes a more reliable signal for identifying reckless or inefficient operation in marine environments. 

#3 NOTIFY OPERATORS WHEN ENTERING DEEP WATERS

If the boat is equipped with depth transducer, fleet operators can use its data to create safety geozones and immediately alert the renter of their dangerous behaviour.

In short, depth transducer is a sensor typically located in the hull of the boat that uses sonar technology to measure water depth, map underwater structures, and water temperature. Here’s why it’s important:

Water depth

Deep areas limit safe manoeuvring and anchoring, while grounding on a shallow seabed damages the vessel. Even if fleet managers give clear safety instructions, conditions change. Tides shifts and sediment moves constantly modify seabed.

Hence, renters need clear support to monitor how much water lies beneath the vessel. With FMx650 trackers, operators can measure water depth relative to both the sensor and the water surface. By continuously tracking depth over time, operators can refine routes, avoid risky areas, and improve overall trip safety.

Water temperature

Depth transducers often also report water temperature. While this may seem secondary, it has real operational value: temperature affects engine cooling efficiency in raw-water-intake systems, and can signal shifting currents. In commercial fishing operations, it’s a primary signal for locating target species.

#4 NOTIFY ABOUT DANGEROUS WEATHER

Another common sensor on board is a wind transducer, which continuously measures wind speed and wind direction relative to the vessel. Its data helps in early detection of dangerous weather conditions, such as approaching storms, strong gusts, or sudden wind shifts.

With FMC650 and FMM650 trackers, operators can analyse parameters such as average wind speed and rapid changes in wind direction. For example, alarms can be triggered when wind speed exceeds safe operational limits or when abnormal wind patterns indicate deteriorating weather conditions. These alerts enable proactive decisions, such as reducing speed, adjusting course, or returning to port, helping to protect both the vessel and its passengers.

In addition to safety benefits, wind data can be used for performance optimisation. When combined with GPS, heading, and speed data from the tracker, operators can assess how environmental conditions impact fuel consumption and vessel handling. This allows crews to sail more efficiently by working with prevailing winds rather than against them.

#5 PREVENT RECKLESS BEHAVIOUR AND DAMAGE DISPUTES

Finally, telling renters upfront that the vessel is tracked deters most reckless behaviour before it starts. This is a simple reminder during instruction, but it can help avoid damage to the machinery by making renters conscious of their behaviour.  Especially, during the peak season, when downtime might cost €5,000–€20,000 per day in lost revenue.

Moreover, if someone returns a boat damaged and claims it was like that already, operators have proof of when the vessel systems came under stress. This way, damage disputes and insurance claims are straightforward to resolve. 

What tracking data reveals about damage and misuse:

READY, SET, TRACK

Tracking the right data makes all the difference in marine fleet management. For telematic solution providers looking to enter the recreational boating market, the opportunity is clear: operators are sitting on a goldmine of NMEA 2000 data they currently cannot access or act on.

The solutions that will win in this market are the ones that bring that data to shore in a way that is simple, actionable, and reliable.

Key capabilities to prioritise:

• Real-time tank level monitoring with threshold alerts

• Engine data analysis for skipper behaviour and fraud prevention

• Depth and water temperature data for safety geozoning

• Wind data for weather alerts and route optimisation

• Clear activity logs for damage disputes and insurance claims

WHY CHOOSE FMx650 TRACKERS WITH NMEA 2000 FOR BOAT MANAGEMENT?

By choosing FMx650 trackers, you invest in a powerful gateway. Not only they seamlessly connect to the NMEA 2000 network, but they also feature multiple inputs for external devices.

As such, you can connect Iridium satellite modem to always be aware of the location even in places with no cellular coverage. Or you can connect liquid sensors, RFID readers for driver identification and navigation tablets.
