Windsurfing you burn about 500 to 1000 calories per hour depending on the workout intensity.
Brisk walking you burn about 400 calories per hour.
From a overall benefits point of view Windsurfing apparently is the better form of exercise as it works more muscle groups.
Either way I certainly know I'd rather windsurf for 30 minutes then go running.
This is what I recorded:
I stepped on the scale in the morning 102.5kg .
Three hours of Winter sailing. Frequent waterstarting, cold water, raining non-stop...
Then a big dinner followed by a half a bottle of wine....
Stepped on the scale next morning 99.8kg.
I think the combo of cold weather/water and frequent waterstarting takes a lot of energy.
But holding onto a gear for a few miles will cause some muscle burn too.
