A buzzword at the 2023 International Boat Builders Expo (IBEX) was “telematics.” Marine telematics refers to app-based systems that enable remote boat monitoring, including boat locations, speed, engine data, bilge-water depth, hatch positions, maintenance requirements and more, reporting them to you via Wi-Fi, cellular or satellite, wherever you are.

You also can control some systems remotely from anywhere on Earth. It’s the Internet of Things, as they say.

Major marine manufacturers such as Brunswick and Yamaha are developing their own remote boat monitoring systems to seamlessly integrate into new boats. Some systems are also available for do-it-yourselfers or dealers to install on existing boats. So, what can telematics do for boaters? With boat theft an issue, location services are a big part of what they do. When activated, some telematics systems can be programmed with a geofence that alerts you if the boat departs a selected electronic perimeter. Each of the following five manufacturers’ systems have their own priority functions and strategies for implementation.

Skyhawk Oversea

Oversea runs on replaceable AA batteries that give it life for from 1 to 5 years depending on how it is used. Ongoing tracking takes more power and on demand geo location takes the least. The wireless hub connects to dozens of sensors designed to do simultaneously such things as monitor hatch closures, battery voltage, bilge water, interior/exterior temperatures and more. Because it is designed to run on internal power, installation is as simple as locating the hub, power it on and then, using the app begin connecting sensors. The remote boat monitoring app gives you full information about your boat at a glance, and allows you to arm, disarm or adjust the geo fence remotely.


The Oversea wireless hub is about 4-inches square and costs $299, alone, $449 with three sensors and $599 with six sensors. In addition to indoor and outdoor geo location and sensor monitoring, the hub also monitors compass heading and so notifies the owner if that changes. Each additional sensor (examples of coverage include, motion, temperature, smoke, sound and more) is wireless, operating on its own disposable internal batteries and easy to install with included screws or adhesives.

BoatFix provides boaters a concierge service of tech- and power-savvy personnel within an easy phone call should any system on board refuse to function properly, even on a Sunday morning. BoatFix partners with boat companies such as Sea Pro and Carefree Boat Rentals (with more to come) to provide factory-installed systems with three-year monitoring contracts. While some brands focus primarily on data collection and analysis, BoatFix focuses on the boater, having a 24/7 concierge desk where somebody with skills is always available. Normally offered as an OEM product, the remote boat monitoring system is free for up to three years to a new boat owner, but requires a subscription fee to continue the service after that time period. 


BoatFix requires no hardware for the concierge. However, it makes three accessory devices to remotely monitor your vessel location and has certain systems in conjunction with concierge services.

BFQL 200: This is its most popular device designed to track your boat’s position and onboard voltage, and report it to you and your concierge once every hour with the ignition off and once every minute with the ignition on. It requires no peripheral devices to do this job.

BFQL 300: This device is enhanced from the BFQL 200 with the addition of reporting bilge-pump cycles to the system, keeping boaters informed of trouble. 

BFQL 100: This is a self-contained, self-powered device to monitor and report boat position once per day for three years on its internal battery.

BoatFix’s 24/7 concierge desk is staffed with propulsion and boat-systems experts who can help diagnose malfunctions and often offer a strategy to repair them on-site. The company guarantees that skilled personnel will be in place to answer the phone and help solve any onboard issues. Its monitoring systems range from a simple, discreet GPS tracking device (BFQL 100) to a networkable system that can report the boat’s position within and without a geofence, notify the owner when the ignition has been engaged, and report repetitive bilge-pump cycles, which could indicate a hull penetration.

The App

The BoatFix Pro app provides a view of your vessel’s location and geofence region, records trips, and helps set routes via web-based mapping. It also gives fast access to towing services, and assists in communicating with concierge services for on-location repairs when possible. It could be called peace of mind on your smartphone.

Subscription Fee

$99 annually after initial three-year period.

Radian IoT

Radian’s founders established their company to partner B2B2C systems to assist boaters, builders, dealers, and financiers in managing their sport and business. Telematics capture an impressive amount of data about boat usage. With it, maintenance decisions can be made, product weaknesses and resulting improvements can be identified, and security information is reported to keep builders, financiers, and dealers aware of inventory status. 

Boater usage data can also help builders and dealers make purchasing and marketing decisions based on regional boating trends. The benefit to the boat owner is having the ability to monitor a boat remotely for the vessel’s safety, security and practical maintenance. Suppose, for example, that your engine regularly exhibits high temps. The M3 notifies you and your dealer that a water pump might need service.


The gateway to all this data is the factory-installed Radian M3 device, designed to give boaters an enormous advantage in operating and maintaining the boat and its security, and enabling a dealer concierge service to the consumer. Many of the monitoring capabilities are built into the M3, eliminating some sensors.

The device monitors two battery banks, bilge-pump cycles, ambient temp, G-forces (up to 2 G), and if the battery is on or off. It notifies the dealer and the owner via text message and the Radian app if service is required. Radian M3 does not create a geofence, but Radian’s Safe Zone system notifies the owner via the app if horizontal motion activates G-force sensors or an ignition sequence begins.

Bluetooth Hub 

With the hub, tire pressure and temperature sensors can be monitored while trailering. 

The App

Radian IQ gives a visual report of vessel status, location, and surrounding weather conditions, and provides access to some user- or builder-selected accessories.

Subscription Fee

Subscriptions may run one to three years by the manufacturer. Thereafter, renewals are $108 per year.
