Has any one done the maths on kite sailing yet to determine its top possible speed, it woild be a fairly hard one to estimate but at some point the kite surfer will just be pulled out of the water by the upwards and sideways froce from the kite, larger finns may be needed but these will have a slowing effect as would adding some weight to hold the board in, perhaps a lead finn, I think the record in kites must be close to its boardable limits, hope they can go way faster, but i think we will see some larger foiling multis have a serious shot at it in the future
