None of the 50 vessels our AIS feed observed within 25 nm of San Diego between 29 Apr 2026 and 5 Aug 2026 broadcast an IMO number on the OFAC, EU, UK or UN sanctions list today. The feed saw only part of the traffic, so this does not mean no listed vessel called here. The feed has delivered no positions since 5 Aug 2026, so these figures will not change until it resumes.

Between 29 Apr 2026 and 5 Aug 2026, ArcNautical's AIS feed observed 50 distinct vessels at San Diego, with Cargo making up 19% of those with a ship-type code — lower than the East Pacific regional average of 34%. San Diego in USA sits along the western coast of the Americas, where commercial shipping operates against a backdrop of seismic, volcanic, and ENSO-driven weather hazards. The Pacific Ring of Fire generates significant seismic and volcanic activity along the entire coast; Chile and Peru experience major earthquakes with sufficient frequency that seismic risk is material for both port infrastructure and voyage planning. The Panama Canal — the key chokepoint connecting the eastern Pacific with the Caribbean and Atlantic — has faced drought-related transit restrictions that limit vessel draft and daily transit capacity, forcing some operators to route via the Strait of Magellan or Cape Horn. El Niño/La Niña cycles produce sustained shifts in storm tracks and sea states.
Routed sea distances from San Diego to the principal global hubs, computed by ArcNautical's routing engine — around land and through the canals a ship actually uses, not great-circle.
Our AIS feed observed 50 distinct vessels at San Diego between 29 Apr 2026 and 5 Aug 2026; 42 carry a confirmed AIS ship-type code. The most common categories:

San Diego falls under the US Coast Guard. The US Coast Guard operates its own Port State Control programme rather than participating in a regional MoU. The USCG Port State Control Annual Report publishes detention statistics by flag and class society. ArcNautical evaluates per-vessel detention probability using flag performance (USCG QUALSHIP 21 status where applicable), vessel age, deficiency history, and ownership opacity.
