Frequently asked questions

How does SeaETA estimate transit time?+

SeaETA combines approximate sea route distance with vessel speed in knots to estimate transit duration and ETA for planning workflows.

Is SeaETA suitable for navigation or voyage execution?+

No. SeaETA is for planning and visualization only. Route output is approximate and should not be used for navigation or official voyage execution.

Can I compare different route assumptions such as avoiding Suez?+

Yes. The calculator can compare approximate route outcomes, including scenarios that avoid the Suez area, to support chartering and voyage planning discussions.
