- Each has a real cost: DNV Navigator Port nothing is published about pricing and licensing is per vessel through DNV sales, so a fleet cannot estimate cost without a commercial conversation.; 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: DNV Navigator Port covers Port clearance packs, Harbour Assist covers Berth and mooring management.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
DNV Navigator Port
- Nothing is published about pricing and licensing is per vessel through DNV sales, so a fleet cannot estimate cost without a commercial conversation.
- It is a point solution covering clearance and crew hours only, so it adds another shipboard system to install, update and train crews on rather than consolidating existing ones.
- The onboard component is a Windows installation that needs periodic updating on each vessel, and update discipline across a fleet with rotating crews is a genuine operational burden.
- Content coverage is deepest for major commercial ports; operators calling at small or remote terminals will still assemble some documentation manually and pay for a dataset that does not cover their edge cases.
- DNV is a classification society selling software to the same operators it classes, which some owners view as a conflict when choosing systems that generate compliance evidence.
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
DNV Navigator Port: How often is port information updated?
Weekly to the onboard installation, which is the main thing the subscription buys.

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.
DNV Navigator Port: Does it work without internet?
Yes. The onboard component is built to operate through satellite connectivity loss.
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.

Yes, it calculates against selected MLC and STCW regimes and warns on breaches.
Harbour Assist: Who owns it?
ClearCourse, a private-equity-backed group that acquires vertical software businesses in the United Kingdom.
DNV Navigator Port: Is pricing published?
No. It is licensed per vessel through DNV with fleet agreements negotiated.

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