MAREC paired with BRNKL Black provides a secure, high-frequency data package for measuring operator and vessel impact exposure in demanding maritime operations. It supports standardised human factors data capture for the NATO HFM RTG-419 programme.
For defence organisations, government agencies, research institutions and professional high-speed craft operators.
High-speed boat crews routinely operate in environments where rapid-onset impacts create fatigue, musculoskeletal load and concern around longer-term brain injury risk. The NATO HFM RTG-419 programme focuses on improving the understanding of these exposures through standardised data collection.
Establish the incidence of impact-induced injuries and cognitive symptoms among operators.
Define the levels and characteristics of human impact exposure at sea.
Explore which impact levels are sustainable and which are injurious.
Support recommendations for training and operational exposure.
Inform smart signal solutions for real-time operator guidance.
Use the data to refine operating practices, reduce harmful exposure and support safer future high-speed craft operations.
The BRNKL NATO Study Package combines MAREC high-frequency motion data collection with BRNKL Black secure mission recording. BRNKL product literature states that this hardware pairing is specified for the NATO HFM RTG-419 human factors programme.
Three wired 3-axis impact sensors are included as standard, supporting measurement across the hull, seating and operator positions.
MAREC accelerometers capture motion data from the hull, seats and operator measurement points.
MAREC sends high-frequency motion data to BRNKL Black.
BRNKL Black fuses motion data with GPS and other vessel data.
The system creates one time-synchronised mission record.
Data is transferred through USB, secure download or automatic transfer where configured.
Local capture does not require internet access or a live cloud connection.
For dedicated high-speed craft, fleet trials and repeatable operational monitoring.
For vessel-to-vessel deployments, trials, research activity and temporary operator studies.

Multiple MAREC devices can be added to expand sensor coverage across operators, seating positions or the wider vessel.
BRNKL Fleet can ingest and contextualise data from MAREC and BRNKL Black, giving operators a wider view of impact exposure, vibration patterns, fleet readiness and maintenance risk.
Map impact hotspots
Track hull, crew and equipment exposure
Identify emerging impact or vibration patterns
Support readiness and maintenance decisions
Mission Dynamics supports European operators with BRNKL Black, MAREC and the wider BRNKL monitoring ecosystem. We help specify the right package, discuss installation or portable deployment and align the system to the operational need.
