Chart every what-if. Commit the course that holds.
Horizont is the berth and voyage planner for fleets that can't afford surprises. Fork the live schedule into a scenario, test it against every berth, then merge it through review — while today's schedule keeps sailing untouched.
One chart table for the whole fleet
Spot the clash before the pilot does
Every change is checked against every berth, vessel and transit as you make it. Each conflict comes with up to five ranked fixes: a time shift within seven days, an alternative berth that fits the hull, or a bulk shift of everything downstream.
| Check | Rule | Severity |
|---|---|---|
| Berth overlap | Two calls share a berth in the same window | Hard |
| Physical fit | LOA, beam or draft exceeds berth limits | Hard |
| Transit | Required speed exceeds the vessel's maximum | Hard |
| Cargo | Berth doesn't handle the vessel's cargo type | Soft |
| Actuals slip | A late ATA pushes downstream calls | Soft |
Plot it on the chart table, not from the bridge
Underway in an afternoon
- 1 Load fleet & ports Vessels with IMO, LOA, beam and draft. Ports with berths, limits and local time zones.
- 2 Lay down voyages Add port calls. Horizont suggests the transits in between.
- 3 Muster the crew Invite planners, port agents and owners with a link. Each gets exactly the access their role needs.
Everyone on the right watch
| Role | Typically | Can |
|---|---|---|

| Global editor | Planners, schedulers | Edit any schedule; build and submit scenarios |
| Port editor | Port agents | Record arrivals and departures at their assigned ports |
| Viewer | Owners, charterers | Read schedules and shared views |

Questions
Can a scenario break the live schedule?
No. Scenarios are separate copies. Nothing reaches live until a supervisor approves the merge, and recorded actuals always win.
What happens when we lose signal?
You keep working on the last synced schedule. Changes queue on the device and sync when you're back online.
How are transit distances worked out?
From a port-to-port distance matrix in nautical miles. Pairs not covered fall back to great-circle distance, and you can override any figure.
Which time zone does it use?
Everything is stored and planned in UTC. Port calls also show port local time, daylight saving included.
Is there a free plan?
Yes. Free covers up to 10 vessels and 5 active scenarios. Team, for up to 30 vessels and 10 active scenarios, is coming soon.
