RE: Uphauling a 10 m sail on shortboard (iSonic 133)
I think it's harder than some of these guys are implying, but you will probably be able to do it with some practice.
I would say that if a board has at least 50 liters more volume than your weight in kg, you will be able to uphaul it pretty easily. (For you that would be a 128 liter board). And with practice, you should be able to uphaul a board with just 20-30 liters more volume than your body weight in kg. (For you that would be 105 liters). Anything less than that and you will have to be extremely skilled to uphaul.
