The short version

  • Each has a real cost: NAPA Fleet Intelligence model-derived performance from AIS and noon reports is an estimate, so it supports fleet screening and dispute evidence better than fine-grained optimisation of a single ship.; Spire Global Maritime now part of Kpler rather than Spire, and spire.com/maritime redirects into the Kpler site
  • They diverge on capability: NAPA Fleet Intelligence covers NAPA Performance Model, Spire Global Maritime covers Satellite AIS tracking.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

NAPA Fleet Intelligence

  • Model-derived performance from AIS and noon reports is an estimate, so it supports fleet screening and dispute evidence better than fine-grained optimisation of a single ship.
  • Pricing is per vessel and unpublished, and modular scoping means the quote you compare against a competitor may not cover the same functions.
  • Building the vessel-specific performance model requires hull form and design data that owners of older or second-hand tonnage often do not have, which turns onboarding into a data hunt.
  • It is a monitoring and advisory layer, not a system of record; you still run a separate planned maintenance system, a chartering system and a crewing system.
  • NAPA is strongest in the design and stability world, and its operational reference base, while real, is smaller than the pure voyage-optimisation specialists, so integration breadth with commercial shipping software is narrower.

Spire Global Maritime

  • Now part of Kpler rather than Spire, and spire.com/maritime redirects into the Kpler site
  • Pricing is not published
  • Sold as a data feed to be consumed through APIs, Snowflake, NMEA streams or FTP, so it needs engineering work before it is useful

Answered from the vendors’ own pages

NAPA Fleet Intelligence: Do we need onboard sensors?

No. NAPA can produce performance analysis from AIS and noon reports using its hydrodynamic model, though instrumented data improves accuracy.

Spire Global Maritime: What maritime data does Spire Global provide?

Spire Global maritime services provide satellite-based vessel tracking and monitoring. The platform offers real-time data on ship locations, movements, and maritime activities for commercial and government use.

Source
NAPA Fleet Intelligence: Does it handle EU ETS and CII?

Yes, emissions calculation and regulatory reporting for EU MRV, IMO DCS, CII and EU ETS are covered.

Spire Global Maritime: How much does Spire Global Maritime cost?

Spire Global does not publish standard pricing for maritime data services. Pricing is determined based on data access level, update frequency, and specific use case. Customers should contact Spire directly for custom quotes.

Source
NAPA Fleet Intelligence: Is it the same NAPA used for ship design?

Yes, same company, and Fleet Intelligence reuses the hydrodynamic modelling from that business.

Spire Global Maritime: What industries use Spire's maritime data?

Spire Global maritime data serves shipping companies, maritime insurance, government agencies, and maritime research organizations. The service supports vessel tracking, compliance monitoring, and maritime intelligence operations.

Source
NAPA Fleet Intelligence: Is pricing published?

No. It is licensed per vessel by module, quoted per fleet.
