Key Intelligence Findings
GPS Spoofing — 35 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 4,222 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Velocity Fraud — 45 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 102.2 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 18 Zigzag Events
Erratic course-over-ground patterns up to 141.5° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.

AIS declared type · Physical capability vs. observed behavior
Type Mismatch Assessment
AIS Declared Type
vessel_type=37 (Pleasure Craft)
Behavior Consistency
INCONSISTENT — year-round multi-port operations with 173 anomalous events are not consistent with pleasure craft use
Speed Capability
Reported 102.2 kn — physically impossible for Type 37 (max ~45 kn high-performance)
Inspection Priority
HIGH — Recommend USCG/CBSA physical boarding and documentation review
