Pup as Husq says for lighter riders I think you could go to maybe 19 inches from what we saw today and other prone boards Kristi has paddled.
She adjusted to the board in less than 1/2 hr. With a more complex double concave bottom shape like the C4 vortices I believe 19 is easily possible.
I have no doubt Kristi could downwind on the board she was riding today!
With width being one of the key factors in how fast the boards travel and with kids crossing over into SUP it won't be long before we see narrower race boards.
We all think we can't until we try.
Phill.
