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
