How about a feature in basecamp that allows one to plot and track cruise ship travel from port to port. Same goes for ferry traffic across rivers and lakes.
Not sure what you're suggesting here. Your GPS will still work if you're on a ferry etc provided it can see the satellites, and Basecamp will show any track recorded by your GPS :confused:
For a cruise, you don't need to have the GPS hooked to a laptop running Basecamp. The GPS ought to work as standalone. Just set the tracking so it records like a point every minute, 60 per hour, 720 points per day and you are set for well over ten days of cruising. Feeding the GPS can be a problem. I would connect it to an external usb power pack like they sell now for cell phones. That would ruin the GPS for several days non stop. Have a second one charged and ready when the first one gets depleted (they generally have led lights to show the charge left). Have regular batteries in the GPS so there will be no interruption when switching power packs. There are even power packs that have a solar panel, fwiw. Put the whole kit and MacBooks in a Ziploc bag, duck tape it to the table on your balcony. Done. Keeping it indoors, near glass might work too, depending on the glass treatment. Outdoors is always better, as anyhow, the ship's structure will obstruct a lot of satellites from view.You can follow your track on screen.It will be best if you downloaded a good area map to the GPS.
While in port, and the ship is not in motion, you can download the track to your laptop and watch it there on Google Earth or Base camp.
I'll be taking my GPSMAP62s on an Alaska cruise next year. I'll probably just leave the tracklog recording method on "Auto" (vs Distance or Time) and Auto Archive "Daily". My main purpose is to use the tracklogs to geotag my photos when I return using BaseCamp. When I'm in the cabin, I'll leave the GPS out on the balcony (in a Ziploc bag); when out and about, it will be on my person. I also have the remote antenna which I may try on the balcony window although, I'd expect the GPS to work better when completly outside.
