My Garmin Etrex handheld (taped to the boom) only records "max speed" and at that time I'm usually too busy trying to keep the boat upright to see what it is! At the end of the day it will only show total distance and total time for an "average speed" which is useless,
Timbo,
The Etrex will show speed between data points. Open the track log in Mapsource, and look at the properties of the track log. It will give you a ton of valuable information.
As an added note, do not save the track log at the end of a sail. Wait until you save it to the computer. If you save the track log using the Etrex, it will truncate the data and make it useless for the information you are seeking.
