BRNKL Black Marine Black Box with Secure Recording and Vessel Telemetry
BRNKL Black is a military-grade vessel monitoring system and onboard data recorder built for defence, police, patrol and commercial marine operations. It captures synchronised video, vessel telemetry, GPS vessel tracking, impacts and alerts in one secure record with full trip replay for incident investigation.
For military craft, police vessels, Border Force, patrol boats, offshore wind CTVs and commercial workboat fleets.
Every data source, time-aligned for review
Synchronised video, vessel telemetry and GPS across deck, helm and engine spaces.
Review an event frame by frame against position, speed, engine data and impact readings. Export a trip report for debrief, insurer or chain-of-command. Data stays on the vessel in 4TB encrypted storage — nothing leaves without your instruction.

MGN 436 Amendment 5 focuses on reducing injury risk from whole body vibration, severe shocks and repeated impacts on small vessels.
It reflects growing best practice around shock-mitigating technology and operational data. BRNKL Black does not replace risk assessment or operator judgement. It gives your team a stronger evidence base for incident investigation, trip replay and exposure review.
For direct helm-facing impact feedback, pair BRNKL Black with Wave Guardian or the most suitable impact monitoring pathway for the application.
Crew impact and shock exposure
For specialist high-speed craft assessment, BRNKL Black can be configured as part of a wider impact and shock exposure monitoring approach. This may include body-worn or helmet-mounted sensors, vessel-mounted accelerometers and, where specified by Mission Dynamics, an optional MAREC-related shock exposure data pathway.
