Key Intelligence Findings
Velocity Fraud — 3 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 99.7 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 61 Zigzag Events
Erratic course-over-ground patterns up to 169.6° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

Vessel Type Analysis
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 123 anomalous events are not consistent with pleasure craft use
Speed Capability
Reported 99.7 kn — physically impossible for Type 37 (max ~45 kn high-performance)
Inspection Priority
HIGH — Recommend USCG/CBSA physical boarding and documentation review
