Key Intelligence Findings
GPS Spoofing — 1 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 5,167 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Evasion Navigation — 19 Zigzag Events
Erratic course-over-ground patterns up to 150.7° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.

Type Mismatch Assessment
AIS Declared Type
vessel_type=37 (Pleasure Craft)
Behavior Consistency
INCONSISTENT — year-round multi-port operations with 107 anomalous events are not consistent with pleasure craft use
Speed Capability
Within or near physical limits for vessel type
Inspection Priority
HIGH — Recommend USCG/CBSA physical boarding and documentation review
