Yeah same here Gorgo. My naish 11'6 is impossible to fall off in glassy conditions but in chop it bobs and rolls like a cork. It's so bouyant that the water hardly comes over the deck (and i'm 105 kegs!) I know from my clubbie days, the lower the seat in the ski the more stable. So in theory the same should apply to a sup, Lower the c.o.g and increase stability. So, i think i will be moving to some thing with less volume(230l seems alot) maybe something around 180l and mostly surf use.
Bring on the Oxbow and PSH demo day at Currumbin on the 30th!!
