Any comparison between windsurfing and s3x is invalid unless the data is generated on the same day! But remember if you sample s3x first and then leave to go windsurfing it WILL be the last time you sample s3x (with that participant). If you sample windsurfing first you will be too knackered for s3x. So the conundrum becomes "how can a valid comparison be made"? More to the point why bother comparing simply enjoy both in moderation.
Didn't realise this was going to be an objective analysis vs subjective feeling.
So, get yourself a tandem board, go forth and conduct your experiments in the manner you suggested.
This method will allow for
simultaneous data capture. vary wind strength and "equipment" to ensure robustness in results.
You may have to report the results both with and without a harness though...
