Hobie-Pedaller, you have it right, although I have not rode my revo into
the sand coming back in. I usually get to knee deep water, hang my legs out, and stand over the yak. I bungie the drive so the fins rest on the hull.
It would be cool if hobie molded in some recesses for the fins, like an air plane's landing gear wheel wells.
I have to say other than the mirage drive, I've seen every make and model
kayak dump it in the right surf combination. Just practice.
