Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
FleetMon
- Service discontinued in January 2024 and fully phased out with transition to MarineTraffic
- Free tier coverage was limited compared to premium plans requiring subscription fees
- Data gaps in regions with poor terrestrial AIS infrastructure before satellite coverage was added
Sea Machines
- Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
- Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
- Pricing is not published and is arranged directly with the vendor
- The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval
