I am starting to plan some electronics
upgrades. One thing I would really like is a decent display of weather
information at the nav table.
I already have some kind of home-type weather
display, inherited from the PO. It shows temperature, moon phase (useful for spring or neap at a glance), time, inside/outside temperature, and it has a good barograph.
That's pretty good already, but I need wind
more than any of these functions. I can get wind
speed and direction relative to the boat's bow on the chart plotter. When at anchor
or on a dock
, I can calculate the geographic wind direction after looking at heading.
But this is pretty kludgy. Plus, there's no trends -- no historic data. It would really be nice to have a display showing at a glance wind speed and geographic wind direction, with historical data (24 hours trend), like my barograph.
I am probably going to install a Maretron or Airmar ultrasonic wind instrument. This will give barometric pressure, too, over the NMEA
network. I have tortured Mr. Google
to death and can't find a dedicated NMEA
weather display - can it be that no such thing exists?
I know I can display this data on a PC or tablet -- but who needs it? I need a small dedicated screen
which will always have this data.
