I could say that it depends, so I better explain my case: 2 years foiling 3 days a week, 75 kg, since 6 six months ago I foil in Moses 679 wing, stab 483, 91 mast, Ocean Rodeo Roam 10m kite and normaly kitting in 8 to 12 knots wind.
I never had any injury with my foil, and only a couple of times I was near to it. So I can imagine it could be not so dangerous, but I will appreciate some advise:
I wached some videos about sanding, and understanding wich parts of the wings are the ones to sand.
1. My foil has never been sanded, I use it 6 months ago, so it is probably needing some sand.
2. Do you think I will notice a big change if I sand?
3. Do you think the risk is low or high?
Thanks for your advice
