Hi Terry, I live aboard have taken 2 cruises south and am planning on heading south this fall ending up in New Zealand from Boston MA. Even funnier is I am also from Vermont. On the last cruise I brought a micro-atx machine hooked to an ICOM M-802 using a SCS Pactor III modem and Winlink for email and weather. Worked great, only problem was it used too much power. So for this trip I have built a low powered computer based on a mini-itx AMD Geode motherboard. I thought I might need the extra power over a EPIA based board, but I was not sure. Right now I have it hooked up the the radio, modem, external WIFI antenna, AIS received and a mux. I am starting to plan out a touch screen monitor for the cockpit.
