Where each one falls short

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

exactEarth

  • Company acquired and redirected; no pricing published on successor site

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
