Beta
I would like to get some feedback (e.g. subjective impression, beta aka angle of the apparent wind, wind speed, board speed, type of board, fin & sail, and any other relevant data) from anyone who has attached a telltale to the nose of their board and has sailed with the apparent wind 90 degrees to the true wind.

Thanks

Barney
