I would expect you’ll be using the tablet for more than just navigation, such as watching videos, listening to music
, keeping lists and also email
/ surfing the net when in range.
Consequently, I would suggest using a tablet that meets all of those needs best.
My observation is that either Android or Apple work
I’ve subscribed fully to the Apple ecosystem and hence I use an iPad
Works well for me, however the major drawback is that I can’t run OpenCPN
Works well with Navionics
and I expect most other navigation apps.
If you do go down the iPad
path, make sure you get a model with GPS
