If a windsurfer cant get down the course on a 20cm fin, then how deep is it?
They, the windsurfers need my 14cm asy MIC fins, used these fins at the speed kiters lagoon north of auckland, i didn't touch the bottom at low tide.

At Luderitz 2nd Lagoon the Kiters are having problems with no where to slow down once they done 500m.
