[regatta]

I'm new to using my Mac onboard. We're an all Mac family and currently have all Garmin equipment on our PS40. I'd like to be able to do more planning for our cruising next Fall - creating routes, examining ports, and general planning. Then I'd like to bring the Mac onto the boat and use those routes on the Garmin. Is this possible? I see Garmin software for Windows but not for the Mac. How can I do this?

Thanks so much.
