Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Spire Global Maritime
- Now part of Kpler rather than Spire, and spire.com/maritime redirects into the Kpler site
- Pricing is not published
- Sold as a data feed to be consumed through APIs, Snowflake, NMEA streams or FTP, so it needs engineering work before it is useful
