You can now get Sup's as light as you want them but at around 4 inches thick these light boards are like corks making them unsettled in the chop.I think too much empashisis is getting put on floatation and you can't sink the board to get it on it's rail. People are scared with on water on the deck when you are paddling and get extra thickess put in to fatten up for the float.

For me to much meat in the sandwich makes the board overly responsive making your feet shift constantly for the sweet spot , maybe the foams are getting too light with no density absourb the bumps.

The litre thing is a bad gauge board profile is much more important , so what if your ankles are wet this can actually make the board more stable than if you float 1 inch above , you might have work a little harder to stay on initally but the peformance advantage is insane.
