I downloaded the Navionics and C-map apps to my iPad to test them out. Unless there is a setting that I have missed neither of them give the light colour/flash sequences for any buoys.
Is this a limitation of the free/trial versions or do digital chart users never sail at night?

We noticed this concerning lighthouses on our isailor app and navionics app. Obviously cardinal buoys have a orientaion defined sequence but the others dont.

To be fair it does say chart plotters are not to be used for navigation, as not up to the same standard as commercial navigation systems, thus presuming them to be an aid to use of paper charts. However we have boldly gone into areas where we have no paper charts in fair confidence that what with our chart plotter and depth gauge we could cope

Generally speaking, such things are additional information that is shown if you select the object concerned. How you do that is dependent on what model of chart plotter you have. On an app, I'd expect tapping or maybe tap and hold on an object to bring up supplementary information like light patterns. Such things would clutter the display too much on a relatively small screen.

On Navionics, you put the cursor on the buoy (lighthouse whatever) and tap to select it. A small window opens and gives you all the details of the buoy: name, light characteristics, position etc. Tap away from the buoy to close the window. It’s the same route to access any hidden information that you’d normally need to put your glasses on to look at on a paper chart.
