The short version

  • Only FleetMon has a free tier, so it costs nothing to try first.
  • Each has a real cost: FleetMon service discontinued in January 2024 and fully phased out with transition to MarineTraffic; Harbour Assist no pricing is published, and the mandatory setup and data migration fee means the first-year cost is materially above the recurring subscription, which is easy to miss when budgeting.
  • They diverge on capability: FleetMon covers Global vessel tracking, Harbour Assist covers Berth and mooring management.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

FleetMon

  • Service discontinued in January 2024 and fully phased out with transition to MarineTraffic
  • Free tier coverage was limited compared to premium plans requiring subscription fees
  • Data gaps in regions with poor terrestrial AIS infrastructure before satellite coverage was added

Harbour Assist

  • No pricing is published, and the mandatory setup and data migration fee means the first-year cost is materially above the recurring subscription, which is easy to miss when budgeting.
  • The vendor explicitly does not discount, so a small harbour has no negotiating room even when the entry point is a stretch for its budget.
  • Ownership by ClearCourse, a private-equity-backed consolidator of vertical software, brings the pricing and roadmap risks that come with that model, and buyers should ask about uplift terms before committing.
  • It is built for United Kingdom and Irish harbour practice, so an operator elsewhere gets a system full of concepts that do not match local regulation.
  • There is no marketplace or booking demand attached, so unlike Dockwa it fills no berths for you; visitor income still depends on your own marketing.

Answered from the vendors’ own pages

Harbour Assist: How much does Harbour Assist cost?

It is quoted by size and complexity. Directory listings put the entry point near 400 pounds a month, and every client also pays a setup fee for customisation, migration and training.

FleetMon: What happened to FleetMon after 2024?

FleetMon was phased out from January 2024 as part of its integration into MarineTraffic following Kpler's acquisition of both platforms in March 2023. The FleetMon brand no longer accepts new registrations or offers new services.

Source
Harbour Assist: Does it bring visitor bookings?

No. It takes online visitor reservations through your own website but has no consumer marketplace, so demand generation remains your responsibility.

FleetMon: Could you track individual vessels in real-time with FleetMon?

Yes, FleetMon Explorer provided live AIS vessel tracking with filtering by vessel class, flag, length, speed, navigational status and signal age, enabling real-time monitoring of individual ships from a global overview to single vessel level.

Source
Harbour Assist: Who owns it?

ClearCourse, a private-equity-backed group that acquires vertical software businesses in the United Kingdom.

FleetMon: What was the starting price for FleetMon Explorer?

FleetMon Explorer pricing started at €54 per month, with subscription plans offering varying levels of access including free basic plans and paid tiers with additional features like historical tracking up to three years back.

Source
Harbour Assist: Does it handle swinging moorings and drying berths?

Yes, and that is one of the reasons British harbours choose it over marina software designed around American pontoon dockage.
