If I may suggest, change the laptop
for a tablet. In my experience they are significantly better than a laptop: less power draw, better apps, easier to hold. In terms of apps:
1. Acrobat Reader - Easy access to your manuals
and reference info.
or a chart plotter specific app like Garmin Helm
. I also like MX Mariner for raster charts
3. Weather+routing, I use Predictwind.
4. HF weather
fax if you are into shortwave. Also navtex app.
5. Earthmate if you like two way satellite
messaging with Iridium
All of the above I use frequently. There is a Windows app for SSB email
called Airmail. I wish they made an Android version.
