I have two sets of charts on the computer: Openseamap and NV BSB
charts. How can I configure the program so I can swap from one to the other quickly and easily?
I suggest you look in the OpenCPN documentation
under Chart Groups. Put different chart types or areas into different folders. Group them as you wish.
You can then select which charts to use by right clicking on the active chart and making your choice under the Chart Groups option.
