A MX3310 can use a SD card instead of a HDD. As a result, it consume only
400mA. I swich the LCD display off when not used and have added a small audio
amplifier (LM386) to get the Opencpn alrms alive. We have a 70Watts solar cell
dedicated to the fridge and two 30 Watts for electronics and ligths. Of course
I have replaced all the light bulbs by LEDs. Since we are totaly autonomus ;-)
Opencpn is now available on Android with good results . . .

Your ebox should be more than capable of this.
I have no PC's on the boat (besides a laptop). What power I have
from the 50 watt solar panel is quickly used by the refrigerator,
TV, stereo, lamps, water pump, lanterns, VHF etc. so I'm looking
into low power solutions. Also, tablets and phones like power too

I am also sailing during 2 month at summer time. We often
go from French Britany to Spain
I use OpenCpn on a MX3310 e-box also managing Jpskmail 2
connected to a FT-100.
Sure a box or a piece of software able to convert APRS
messages to "AIS" would be great as any modern marine display
could display both AIS and APRS.
Good idea, Per,
