I use Garmin Mapsource Metroguide USA. I originally got the software to download detailed area maps into my Garmin GPSMAP76. I now use it more to store my recent races/trips. It is great when you are just out sailing/practicing, as it will show you, on a detailed map, where you have been/how far you went/maximum speed/average speed/etc. It shows a lot of info. Interesting to see elevation changes. I sail on a lake and there are not a lot of elevation changes! When I see one, I like to think that I was "flying high"
.
As to detail, the trip is saved with a series of points (bread crumbs) that show you the speed/heading/time/elevation between each point. One good trip consists of hundreds of points. You can look at a series of points to determine where and what your maximum speed was. If the speed is not consistant for at least a few hundred feet, I would imagine that you were flailing your arms about and you would be getting your maximum "arm" speed...
Could not find the software on Catsailor Online Store. If I over looked it, maybe Rick can point the way. It is found at
