It can be done with thigh straps and technique. A calm pool helps too. Here are a few vids I dug up. Some look pretty ancient – perhaps the mastery of IK rolling has become a lost art.
Of course the fact is most IKs are usually so wide that falling out takes some effort providing you’re not being churned up by The Smelter on the Animas river (left). Getting back in to an IK is usually as easy as crawling drunk onto a sofa. But that’s not so entertaining to watch.
Here’s another. Don’t know what it is but it looks even wider – perhaps a small raft? The guy gives it a go but eventually separates from the boat. Nul point. As the lone youtube comment says: “Nice briefs, bro”.
One more? A Gumotex Safari with a long lever roll. At 28 inches wide it’s narrow for an IK and probably the easiest one to roll (not that I’ve ever done it, mind).
And another. Tahiti is a Sevylor IK, I do believe. Nice execution.
Another Aire – looks like a 36-inch Force river runner. He gets there in the end.
Advanced Elements hand roll with no straps? I don’t think so but thanks for uploading.
More pixels here than Disney, but no long levering required in a vintage Spreu Boote Guppy. What is it with these European IK names?
And finally the Packmaster, Roman Dial and chums demonstrating packraft rolling with and without skirts. There are plenty more packrolls like this on youtube.
