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 "station".
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 technology.
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 and
AIS...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 an
NMEA 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!
