I barrel rolled the ski rather effortlessly, didn't try to flip it because I broke the nozzle on the roll, the bolt came out. It didn't ride nose high. Never got the ski to high speed. I never tried.
I'd imagine it wouldn't take much to flip this hull in the surf. I was tempted to flip it but decided not to because I didn't want to break something and ruin the opportunity for others to ride which I ended up doing anyways :/
you're flipping these days?
