Marine Black Box and Mission Recording

BRNKL Black Marine Black Box and Mission Recording System

BRNKL Black is a secure offline-first vessel data recorder built for defence, police, patrol, coast guard and professional marine operations. It brings together onboard video, vessel systems, location, impacts, alerts and mission playback in one time-synchronised operational record.

For military craft, enforcement vessels, patrol boats, high-speed workboats and mission-critical marine operations.

The black box for boats

BRNKL Black captures the operational picture that conventional monitoring systems miss. It collects, time-synchronises and stores data from onboard systems, cameras, sensors and crew-impact inputs so operators can review missions, investigate incidents and protect the integrity of their evidence.

BRNKL Black tactical RIB deployment

Deployed across defence, patrol and enforcement operations, BRNKL Black provides the secure recording foundation for mission-critical vessel operations where every detail matters.

One secure recorder. Six operational roles.

Record the mission

Capture onboard video, vessel activity, alerts, location and sensor data into one local, time-aligned record.

Replay incidents

Review missions through synchronized video, telemetry, vessel position, event triggers and impact data.

Monitor vessel and human factors

Bring together vessel impacts, crew-impact data and operational events to better understand exposure during demanding high-speed operations.

Support condition-based maintenance

Connect to onboard systems and data networks to identify issues earlier and support maintenance planning before failures become critical.

Operate offline-first

Data stays on the vessel unless you choose to export or transmit it through your own network, private platform or communications route.

Integrate with existing systems

Connect NMEA 2000, Modbus, digital switching, cameras, CAN bus and additional sensor networks into a single recording platform.

What BRNKL Black records and connects

Connect to NMEA 2000, Modbus, digital switching, onboard cameras, sensors and other onboard systems. BRNKL Black brings this data together into one secure recording environment.
Built-in sensors track vessel motion and impacts, while optional external human-factor inputs can add crew-impact data. This supports a more complete understanding of what the boat and personnel experienced during a mission.
Connect compatible marine and IP camera networks to capture video across the vessel. Video can be reviewed alongside operational data, alerts and other mission events.
BRNKL Black supports vessel position tracking where required. For specialist operations, the unit includes physical kill-switch capability to disable transmitting and receiving components, including GPS.
Configured trip reports can be generated from selected operational data points, creating a clearer post-mission record for debrief, oversight or internal review.
Replay a complete mission with video, vessel location where enabled, engine data, sensor data, wave and crew impacts and alert events on one time-aligned dashboard.
BRNKL Black is offline-first. Data stays on the vessel unless configured to transmit through a private network, cloud platform, tactical network or existing communications equipment such as Starlink.

Useful evidence for high-speed craft risk review

MGN 436 Amendment 5 focuses on mitigating the risk of injury from whole body vibration, severe shocks and repeated impacts on small vessels. It also reflects growing best practice around shock-mitigating technology and data. BRNKL Black does not replace risk assessment, procedures or operator judgement, but it gives professional teams a stronger evidence base for mission review, incident analysis and exposure discussion.

For direct helm-facing impact feedback, pair BRNKL Black with Wave Guardian or the most suitable impact monitoring pathway for the application.

Optional human impact and shock exposure integration

For specialist high-speed craft assessment, BRNKL Black can be configured as part of a wider human-impact and shock exposure data 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.

Built for mission-critical vessel operations

Defence and military craft

Secure data recording, mission playback and human-factor visibility for demanding operating profiles.

Police and enforcement vessels

Review operations, onboard events, vessel systems and evidence in one synchronized record.

Coast guard and border operations

Retain clearer operational context around live missions, patrols and incidents.

High-speed patrol craft

Combine video, impacts, vessel behaviour and operator decisions into a post-mission review tool.

Specialist workboats

Support maintenance insight, onboard event review and secure equipment monitoring.

Professional fast craft operators

Strengthen incident review, crew debrief and management oversight where operating conditions are demanding.

Integrated mission recording and vessel data capture across deck, helm and engine spaces. BRNKL Black brings video, telemetry and sensor data together in one synchronized timeline for complete operational visibility.

BRNKL Black digital twin system visualization

Example use case: vessel and crew impact understanding

BRNKL reports that Black was used with a Special Operations Forces organisation to fuse vessel data and biometric sensor data, helping analyse the physical effects of high-speed boat manoeuvres on personnel. The system combined body and head acceleration data from wearable sensors with vessel-mounted acceleration inputs, then brought those data sets together in real time for review.
