Aerial Security Systems

Sovereignty
begins at the
waterline.

Sentinel Maritime delivers military-grade drone detection and classification technology, engineered exclusively for the world's most discerning vessel owners. Silence the sky. Reclaim your horizon.

The exposure
is real.

Commercial off-the-shelf drones have fundamentally altered the privacy equation for high-net-worth individuals at sea. Paparazzi, corporate espionage, and opportunistic surveillance are no longer theoretical. They are operational, daily occurrences across the Mediterranean, Caribbean, and Pacific cruising grounds.

Sentinel Maritime was founded on a single conviction: the same people who accept no compromise in naval architecture should accept none in aerial security.

System Capabilities

Detection that requires
no compromise.

Multi-Spectral Radar
Phased-array radar tuned to the micro-Doppler signature of drone rotors. Effective in sea clutter, rain, and high-electromagnetic interference environments typical of marina berths and anchorages.
Ku & X-Band Fusion
Electro-Optical Tracking
Day/night electro-optical and infrared camera arrays provide continuous visual confirmation. AI-guided gimbal tracking maintains persistent lock on classified contacts at range.
30x Optical — Full Radiometric IR
RF Signal Intelligence
Passive radio-frequency monitoring across 70 MHz–6 GHz. Extracts controller handshake data, identifies drone model by RF signature, and — where legally permissible — resolves operator location.
Operator Geo-Location Optional
Threat Classification AI
Onboard neural inference engine trained on a taxonomy of over 800 commercial and professional drone platforms. Real-time probability scoring distinguishes surveillance-grade payloads from recreational aircraft.
800+ Platform Database
Bridge Integration
Seamlessly integrates with Furuno, Garmin, and custom bridge NMEA 2000 ecosystems. Threat data overlays on existing chart plotters and CCTV systems without requiring separate operator terminals.
NMEA 2000 & 0183 Native
Discreet Notifications
Tiered alert delivery to master, chief officer, and owner via encrypted mobile application. Fully configurable escalation protocols ensure the principal is always the last to be alarmed and the first to be informed.
End-to-End Encrypted

Layered. Redundant.
Silent.

The Sentinel architecture is designed for installation during newbuild or refit with absolute discretion. Every sensor is flush-mounted and finished to superyacht specification. The processing core requires no more rack space than a standard AV cabinet.

"Within the first week at anchor in Sardinia, Sentinel identified three incursions that our crew would never have detected. It has permanently changed how we think about privacy at sea."
