Can a rnc chart be used for voyage planning?

Yes, an RNC (Raster Navigational Chart) can be used for voyage planning as it provides essential navigational information, including topography, water depths, and navigational aids. However, RNCs are raster images of paper charts, meaning they may lack some of the interactive features and real-time data available in electronic navigational charts (ENCs). While they can serve as a useful reference, it's advisable to complement RNCs with ENCs and other navigational tools for comprehensive and accurate voyage planning.
