Features & Capabilities

Nautical Calculator is a free Android application designed for sailors and navigators to perform a wide range of navigation calculations. It supports rhumb line and great circle calculations, providing precise courses, distances, and graphical visualizations between coordinates. The app includes advanced features such as wheel over calculations, compass error detection, draft surveys, and utility conversions.

Additional capabilities cover route planning with world map visualization, celestial navigation with position line and meridian transit, tide and tidal current computations, ETA calculations, and wind speed estimations with Beaufort classification. Highly versatile, it supports various nautical tasks like anchorage, interpolation, and ABC tables for star navigation. While the included map is intended for route display only and not for sailing navigation, Nautical Calculator serves as a complete toolkit to facilitate safe and efficient maritime navigation.
