The short version

  • Each has a real cost: NAPA the Internet Archive's capture of NAPA's homepage on 1 January 2020 named six distinct maritime software products, NAPA Loading Computer, NAPA Emergency Computer, NAPA Logbook, NAPA Fleet Intelligence, NAPA Voyage Optimization and ClassNK-NAPA GREEN, with no price figure published for any.; Sea Machines requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • They diverge on capability: NAPA covers Ship design, Sea Machines covers Autonomous control.

Where each one falls short

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

NAPA

  • The Internet Archive's capture of NAPA's homepage on 1 January 2020 named six distinct maritime software products, NAPA Loading Computer, NAPA Emergency Computer, NAPA Logbook, NAPA Fleet Intelligence, NAPA Voyage Optimization and ClassNK-NAPA GREEN, with no price figure published for any.

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
