Key Intelligence Findings
AIS Blackout Confirmed — 1 Event
Deliberate AIS transponder deactivation detected. Each event represents a period where SKADI was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
Evasion Navigation — 84 Zigzag Events
Erratic course-over-ground patterns up to 187.3° 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 177 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
