note OG Fun hull & Torus channel
Does anyone remember the hull on the 1st Gen fun? In surfing now that center channel is on the rise, search Rasta Torus channel.

Looking at that channel made me wonder:

Did it work? Does anyone remember that feature accelerating down the wave face?

Does anyone have thoughts on how loose that channel is for breaking free and spinning or did the interior edges cause drag and catch?

Is a kayak hull carving on one edge fast enough to plane on the outer planeing hull face and shunt water through the channel and create speed?

Does anyone understand what I'm talking about?
