Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Sofar Ocean

  • Sensor data accuracy depends on global buoy network coverage which may vary in some regions
  • Route optimization requires stable internet connection for real-time data access

VesselFinder

  • API access is billed in credits, and a satellite AIS position costs 10 credits against 1 for a terrestrial position
  • Credits expire 12 months after purchase
  • Credit packs start at 330 EUR for 10,000 credits, excluding VAT
  • Tracking a vessel outside terrestrial AIS range multiplies the cost of every position tenfold, so open ocean coverage is the expensive case rather than the standard one
