Is there an easy way to build a display that will show some chosen NMEA
data?
I have seen on the market programmable units that sell for several
hundred $ and I know that a computer is easily interfaced but what I
need is just a simple, cheap and weatherproof repeater at the helm to
display only few of the zillion data available at the underdeck main
navigation station. For example decoding just part of BWC and VTG and
displaying, say, four lines would be enough (COG, heading, bearing to
waypoint, and distance to waypoint).



I think what you are looking for is a CruzPro RP-60 Intelligent NMEA
0183 Remote Data Repeater:

It seems reasonably priced at about $200 USD. I don't think you
could build anything cheaper than that considering development costs
and equipment.


FWIW, I have been using one of these for the last couple of years. It
has performed as advertised, and the manufacturer was responsive to my
queries.
