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.; Wartsila Voyage limited publicly available pricing information requires direct contact with sales team
  • They diverge on capability: NAPA Fleet Intelligence covers NAPA Performance Model, Wartsila Voyage covers ECDIS navigation.
  • 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  • Pricing is per vessel and unpublished, and modular scoping means the quote you compare against a competitor may not cover the same functions.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.

Wartsila Voyage

  • Limited publicly available pricing information requires direct contact with sales team
  • Requires specialized training for bridge crews to operate effectively in different vessel scenarios

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.

Wartsila Voyage: What is Navi-Sailor ECDIS?

Navi-Sailor ECDIS is an IMO-compliant electronic chart display system integrating GPS, radar, and AIS data for route planning and monitoring. It is one of the most installed ECDIS solutions worldwide.

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.

Wartsila Voyage: Does Wärtsilä offer fleet management integration?

Yes. Navi-Sailor ECDIS integrates with Wärtsilä Fleet Optimisation Solution to connect ship and shore, providing fleet teams better visibility and bridge teams streamlined workflows.

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.

Wartsila Voyage: Is Wärtsilä Voyage compliant with maritime regulations?

Yes. Navi-Sailor ECDIS is fully IMO-compliant and designed to satisfy SOLAS Chapter V requirements. It supports S-100 standards for future maritime data interoperability.

Source
NAPA Fleet Intelligence: Is pricing published?

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