The short version

  • Each has a real cost: Sofar Ocean sensor data accuracy depends on global buoy network coverage which may vary in some regions; ZeroNorth zeroNorth reported a net loss of roughly $65m for the 2024 financial year, deepening by around 57 per cent, so a multi-year fleet commitment should include contractual protection on continuity and pricing.
  • They diverge on capability: Sofar Ocean covers Weather routing, ZeroNorth covers Voyage optimisation.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Sofar Ocean

  • Ocean data and marine sciencenot ZeroNorth

ZeroNorth

  • A tanker operator wanting speed decisions that account for the freight market rather than optimising fuel in isolationnot Sofar Ocean
  • A bunker buyer testing supplier quotes against independent fair value pricing before fixing a stemnot Sofar Ocean
  • An owner needing EU ETS and FuelEU Maritime reporting derived from the same voyage data that drives operational decisionsnot Sofar Ocean
  • A charterer evaluating which vessel to take on a cargo based on projected voyage economics rather than on nominal specificationsnot Sofar Ocean

Where each one falls short

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

Sofar Ocean

  • Sensor data accuracy depends on global buoy network coverage which may vary in some regions
  • Route optimization requires stable internet connection for real-time data access

ZeroNorth

  • ZeroNorth reported a net loss of roughly $65m for the 2024 financial year, deepening by around 57 per cent, so a multi-year fleet commitment should include contractual protection on continuity and pricing.
  • The company consolidated operations during 2025, liquidating a Norwegian subsidiary, which is prudent cost control but means local presence and account continuity may not be what was originally sold.
  • Pricing is per vessel and per module, so the headline vessel figure understates the cost of an owner who wants voyage, bunker and emissions capability across a fleet.
  • Recommendation quality depends on the quality of noon reports and vessel data supplied, and an owner with poor reporting discipline will get poor optimisation regardless of the algorithms.
  • It sits between technical performance tools and chartering systems and fully replaces neither, so most owners run it alongside an existing voyage management system and pay for overlapping capability.

Per vessel and per module on subscription, typically multi-year and quoted. Nothing is published.

Sofar Ocean: How does Sofar Ocean collect ocean data?

Sofar operates the world's largest real-time ocean data platform using a global network of spotter buoys deployed across half the world's oceans to provide accurate weather forecasts and marine data.

Source
ZeroNorth: Is ZeroNorth financially stable?

It is well funded, raising $20m in February 2025, but reported a net loss of roughly $65m for 2024. Treat continuity terms as a contractual issue.

ZeroNorth: Does it need onboard hardware?

No. It works from noon reports, AIS and existing vessel data feeds rather than requiring its own collection box.
