Tuule Liinid
Estonian island routes with vehicle decks booked to the metre, between the mainland and the western islands.
All cases
BORA Systems is a ferry operations platform built in Tallinn, Estonia — 33 modules across 6 functional categories, each on its own microservice with a local API. Certified to ISO/IEC 27001 and GDPR-compliant. As of 2026, in daily service across three regions: the Baltic, the Channel Islands and the Persian Gulf.
What is the route?
Tuule Liinid connects the Estonian mainland to its western islands, carrying passengers and vehicles across short but weather-exposed crossings. It runs 18 scheduled sailings a day on 3 routes and carries more than 120,000 vehicles a year.
Vehicle decks are booked to the metre, measured at the gate against the deck plan, so a full sailing is genuinely full rather than optimistically booked.
What runs on BORA here?
Tuule Liinid runs on BORA Systems: booking and sales across the passenger website, the agency interface and onboard, boarding validated at the ramp by Access control, and revenue drawn straight from live operations by Reporting — every channel writing into one shared ledger.
Boarding is validated on handheld devices that stay fully functional offline and reconcile when the link returns, so a lifeline crossing is not blocked by a dropped connection. Access control is built to the ISPS Code — adopted by the IMO in 2002 and in force since 2004 — so the departure manifest meets the security obligations a passenger vessel carries.

Frequently asked questions
Where does Tuule Liinid operate?
Tuule Liinid operates in the Baltic, connecting the Estonian mainland to its western islands on short, weather-exposed crossings. On BORA Systems it runs 18 scheduled sailings a day on 3 routes and carries more than 120,000 vehicles a year, with vehicle decks booked to the metre.
Does boarding keep working when the connection drops?
Yes. On Tuule Liinid's island routes BORA validates boarding on handheld devices at the ramp that stay fully functional offline and reconcile once the link returns, so a dropped connection does not stop a sailing loading.
