Barnacle Systems

Barnacle Systems Inc designs and manufactures security and monitoring hardware for the marine industry. Based in North America, the company provides technical solutions for recreational and commercial boats in more than 40 countries.

The company offers two primary product lines:

• BRNKL Black: A professional-grade data logger engineered for high-stakes missions and industrial fleets. This system uses an offline-first architecture with 4TB of local encrypted storage, allowing for synchronized mission playback, predictive maintenance, and human-factors monitoring without requiring cloud connectivity. It integrates with NMEA 2000 and ModBus to track mechanical stress and security alerts in real time.
• BRNKL Blue and 5G: A monitoring and surveillance hub designed for the leisure market. These devices allow boat owners to track location, monitor battery levels, and view live video through a mobile application. The hardware is compatible with 5G cellular networks, satellite, and Starlink, enabling global visibility of a boat’s status and providing data that can help reduce insurance premiums.

Both systems are designed for rapid deployment, with an average installation time of two hours for new builds or refits. By logging onboard operations and system performance, the technology supports both everyday security and mission-critical analysis.
