Basically, I’ve cut the bottom out of my cockpit. I’ve used silicone to fasten a pair of hip waders to the hole.
When I get tired of sitting all day, now I can slip my legs into the waders, extend them down, and “stand up” with my legs dangling underneath the kayak… It helps if I kick, like a swimming motion.
I’m working on a roll, but, with my legs down I’m finding it difficult to turn over in the first place.
