Open, unrestricted, moderate to calm waters during daylight, and/or sailing with Crew.
(Or shore-side training and passage planning.)
But! …. If you are sailing as a ‘Billy-no-mates’, in the dark (not dusk), in restricted waters, in rough weather, taking spray in the cockpit, wearing spec’s, you definitely need a dedicated, waterproof, marine chartplotter located in plain sight under your sprayhood.
