Where each one falls short

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

DTN

  • No pricing published on vendor website; requires contacting sales team
  • Customized pricing model makes comparison difficult without direct vendor engagement

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.

Interested customers must contact their sales team through the 'Talk With an Expert' form for pricing information.

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.

DTN: What is DTN's pricing model?

DTN offers industry-specific solutions with custom pricing based on client needs and deployment model. The company does not use standard tiered pricing or publicly available rate cards.

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.

Harbour Assist: Who owns it?

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

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.
