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.; 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 Fleet Intelligence covers NAPA Performance Model, Sea Machines covers Autonomous control.
  • 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  • Pricing is per vessel and unpublished, and modular scoping means the quote you compare against a competitor may not cover the same functions.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.

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

Questions people ask

Is NAPA Fleet Intelligence or Sea Machines better?
Neither clearly leads. NAPA Fleet Intelligence starts at On request and Sea Machines at $50000/one-time, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, NAPA Fleet Intelligence or Sea Machines?
NAPA Fleet Intelligence starts at On request and Sea Machines at $50000/one-time.
Does NAPA Fleet Intelligence or Sea Machines run on more platforms?
NAPA Fleet Intelligence runs on Web, Cloud. Sea Machines runs on Embedded, Web, Mobile.
What is NAPA Fleet Intelligence best used for?
NAPA Fleet Intelligence is most often used for a charterer assessing hull performance of vessels it does not own using ais data alone, an owner needing auditable cii and eu ets numbers rather than spreadsheet estimates, a technical manager deciding whether hull cleaning this quarter pays for itself in fuel, a fleet arguing a charter party speed and consumption claim and needing model-backed evidence. Of those, a charterer assessing hull performance of vessels it does not own using ais data alone and an owner needing auditable cii and eu ets numbers rather than spreadsheet estimates are not what Sea Machines is typically brought in for.
What can NAPA Fleet Intelligence do that Sea Machines cannot?
NAPA Fleet Intelligence covers NAPA Performance Model, AIS-based analysis, Voyage optimisation, Emissions reporting. Sea Machines covers Autonomous control, Remote operation, Collision avoidance, Pattern following.

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.

Sea Machines: How much does Sea Machines cost?

Pricing is not published. Sea Machines requires customers to contact their sales team directly through the Contact Us link on their website for pricing quotes tailored to specific products and use cases.

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.

Sea Machines: What is the pricing model for Sea Machines products?

Sea Machines offers autonomy systems and software solutions for maritime vessels. Pricing is determined on a per-product basis through direct sales consultation rather than published subscription tiers.

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.

NAPA Fleet Intelligence: Is pricing published?

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