Rolling vs sculling
I have seen this roll done and well it's not rolling a boat with one sweep. It's done by sculling the boat over. So, it would only be possible in either a ultra skinning greenland style kayak or a squirtboat. I'll try some the next time I'm in the Angst. But, knowing how it is preformed I dought it can be done with a modern kayak paddle. It would be better suited for a greenland style paddle as well. Something that would allow you to scull off both sides of the blade without finding resistance in the balde transition.
Confluence Kayaks in Denver has it on VHS, call Jon and he maybe able to find it for you. 'Rolling with Maligiaq' is the name of the video.
I love to dance, but who needs the music- It throws me off.
