MaritimeHub for Android

Product summary

MaritimeHub is a free, offline navigation application built for ship officers and seafarers. It consolidates a broad set of calculators, navigation aids, and reference materials into one portable package so mariners have essential tools available while underway, even without an internet connection.

Offline strengths

Because the app functions without network access, it is suitable for use at sea where connectivity is limited. All core utilities and many reference resources remain available while on passage, improving operational readiness during voyages.

Core calculators and navigation aids

• Draft correction modules for a variety of conditions
• True wind and wind-related computation tools
• Voyage leg reporting and summary generators
• Estimated time of arrival (ETA) computations

Reference datasets and charts

• Extensive ports directory with detailed entries
• Tide height computation utilities
• Coverage maps showing NAVTEX transmitter areas and reception zones

Live positioning and monitoring

• Distance-to-waypoint readouts for ongoing legs
• Instantaneous speed tracking from GPS
• Course-over-ground and heading monitoring in real time

Practical notes and safe use

MaritimeHub is a practical companion for professional navigation, but it should not replace official navigational publications and approved instruments. Always confirm critical data against authorized sources and company procedures before acting on it.
