Hi guys,
I'm still a beginner but progressing nicely. Last weekend when I was out, I had to self-rescue but I am not sure what happened.

I was just trying to water start after I had body dragged out but all of a sudden a small gust came and my loop unhooked and the kite fell out of the sky right into the ocean with me still being connected by the one line. It fell right into the middle of the window on the leading edge in the water and instantly started dragging me dangerously with me going under water. I instantly looked around for my 2nd safety and ejected from the kite completely.

I had to swim in, recovered the kite and the board and went out again.
It wasn't really scary thanks to me having practiced with the safety before but it did make me wonder why this happened. Someone previously pointed out to me that my donkey dick is pretty soft (esp. when wet).
I'm flying a 2013 BWS Noise but feel like the bar and lines are a bit older (bought it used). I also find it impossible to use the depower on those lines, I don't seem to have enough strength to pull it in if I need to.

Any thoughts?
