Key Intelligence Findings
AIS Blackout Confirmed — 5 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where OSG COURAGEOUS was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
GPS Spoofing — 2 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 5,418 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Velocity Fraud — 1 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 86.4 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 109 Zigzag Events
Erratic course-over-ground patterns up to 116.8° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

Type Mismatch Assessment
AIS Declared Type
vessel_type=37 (Pleasure Craft)
Behavior Consistency
INCONSISTENT — year-round multi-port operations with 204 anomalous events are not consistent with pleasure craft use
Speed Capability
Reported 86.4 kn — physically impossible for Type 37 (max ~45 kn high-performance)
Inspection Priority
HIGH — Recommend USCG/CBSA physical boarding and documentation review
