Could you build this?
Partial The ETA calculator and chart UI are codeable, but a credible port-to-port distance matrix needs licensed maritime route and port data, and IMO compliance logic needs domain verification.
What it would actually take: The UI can be built as a web or desktop app with a mapping library such as Leaflet or OpenSeaMap, plus routing over a graph. The hard parts are a licensed, accurate sea-distance and port dataset (such as the NGA World Port Index or commercial sources) and correct implementation of IMO A.893(21) rules. That requires a maritime navigation expert to validate outputs before officers rely on them.
