Now I can see sense of so many kiters riding around you .

They could be easy trained to help windsurfers in the need

So far we had to relay on our-self or passing boat and jetskis.
I use to sail with spare 2m long thinn line in my harness pocket.
That possibly reminder of the early time we need a lot of assistance when gear break or skills inadequate was a daily occurrence in our group.
But it looks that towing windsurfer by kiter could be easier then by fellow windsurfer ! (?)
So far we help on many occasion kite surfers to retrieve their boards (and my spare line is very helpful on such occasion too).
