shipETA

shipETA is an offline voyage planning aid for ship officers. Calculate Speed Required, Best ETA, Latest ETD, and bunker estimates with Zone Description (ZD) wall-clock times, built for pilot-station to pilot-station sea passages.

WHAT YOU CAN DO • Speed Required: sail time, required dock ETA, pilotage, and distance to required open-water SOG • Best ETA: sail and SOG to pilot-station arrival and dock ETA • Latest ETD: required dock ETA and SOG to latest sail and departure • Fuel: cube-law estimate from two speed / MT-day references, with optional burn band • Routes: save and reopen passages on device • Vessels: performance profiles (SOG and cube-law refs) you can link to a route • Whale zone: SOG cap for ETA/ETD; segmented WZ distances for Speed Required • Share: export a PDF or copy a text summary via the system share sheet

BUILT FOR THE BRIDGE • Works fully offline. No account, no cloud sync • ZD as a signed UTC offset (including half hours) • Clear timeline: sail, pilot out, sea passage, pilot in, dock • Local storage only for routes and vessel profiles

IMPORTANT shipETA is a planning aid. Results are estimates from the values you enter and are not a substitute for official navigation systems, company procedures, or the Master’s judgment. Always cross-check before use.
