Hi Groundhog. I have no idea how much sailing you plan on doing. i.e., daysailing, long distance cruising, overnighters...Important to know because the extent of your sailing will drive the investment you will need to make in charts and software.
If you are just doing a daysail here and there. I would suggest getting the local laminated charts that you can look at in the rain and a hand-held Garmin GPS.
