I have been using my Northstar 6000 chart-plotter for navigation
planning. I would like to start using my Mac for these purposes, but not exactly sure where to start? I guess would basically need some type of software
NavX, etc) and new GPS
antennae to hook to the MAC. Is there one software
that people prefer over another? How do you acquire charts
? We plan on possibly circumnavigating, so we will eventually need charts
for a good portion of the world, is there an economical way to acquire such a quantity of charts?
