Problem iswhen u have the water stream running to the same direction as the wind....Lot of skills needed..A board with a daggeboard is recommended for beginners...
I’m also a beginner so please don’t take this as the proper way but what I do is use the sail to get the board to come around in the right direction to the wind and then re sheet the sail. Like I’ll stand up on the board and use the wind to bring the board around.
