Chart plotters at nav station are not very useful to loo at underway.. unless you have tine. Programming a waypoint takes a few seconds and it's important to have that data accessible from where you steer... AP or helm
GPS plotter is super to give you context as you sail... and so that belongs visible from the steering
I use an AP and so helm mounted display would rarely be seen... except when I drive through anchorages
and in harbors.... and then I more likly need eyeball visuals.
Laptops beiong in nav stations... Perfectly fine for planning and is there is a navigator.
Now the rage is a mobile device. Not a bad idea... Get familiar with touch screen
You may want radar
overlay... then you are into networking. You will figure what a makes sense for you. I have an MFD w/ radar
...a portable 7" plotter I mount in a winch
under the dodger
... Android phone
with charts and so forth. Laptop is not used for nav.
I have cockpit
dash mounted instruments
repeaters for the MFD. A waypoint is programed below... data visible in cockpit
and the 7" plotter is used most when sailing. I don't usually enter a waypoint in 7". It has no radar input.
Everyone finds what works for their way of sailing. There is no best way!
