xMark MEGA ROFTL ... I wish I could learn from her ...
Well IMHO Kite is harder to learn and less safe ... If you break the kite in the middle of the ocean, like here ... there you are, you can't easily go back home.
Now, at least, I have a huge 200 board which float very well ...

About the painful, especially here, kiter are still seen as bad guys because the space in Bermuda is small and tourist and kiter do not fit well in the same spot, if you get what I mean.
Finally, no windsurf is not harder to learn, from my point of view kiting is more difficult to learn than windsurfing for sure ...
The only way to compare the two sports is to try both of them.

Anyway we are having now 2 hurricanes so this long week-end is waisted ... I was already planning to spend the whole week-end on the beack with my gear ....
