If you need the board to float you then you need at least +30 liters (140-145 litres), but that still means wet feet when pulling a big sail. With +40 liter you will be comfortably dry in the rigg pulling phase.
This is most definitely true. I'm 57kg now and uphauling my 93l Futura my feet are wet. Which means that at twice my weight you would need twice the volume I'm using to get the same buoyancy, ie. 180l.
