Description
SailNav – Nautical GPS Offline is a full-featured navigation app built for maritime use. It isn't designed for vessels sailing far from shore or heading to foreign waters, but it works very well for everyday boating or as a reliable backup system. You can plan routes while factoring in fuel reserves, wind, weather conditions, and more. The app also highlights points of interest and restricted zones, and it includes tools that help you think through possible scenarios and prepare emergency responses ahead of time.
