Lessons: Wind Surfing and Wake Boarding

[Killevippen]

I could use your help. Last year I bought a wake board and have make some progress, but my ten year-old has now surpassed me. Any recommendation on lessons for the both of us (either at a school or a private instructor at our beach)?

Similarly, I just bought wind surfing boards, one for me and one for the kids, but have no idea of how to start. Again, any recommendations?

Thanks!
