I now have about 6 1-hour sessions in my Shearwater 17H. I am using the kit standard tractor seat and Rapid Pulse back band along with Smart Track foot pegs and foam knee braces. After about 15 minutes, my left leg starts going to sleep. I can get some relief by taking the foot off the peg and stretching the leg out, but it is temporary. I have had the seat in several locations, but no help. This morning, after paddling for an hour, the leg would not support my weight for several minutes after I crawled out of the boat. This afternoon I am thinking I will go back to the lake and trying a gel seat pad I won at Okoume Fest 2008 as an alternative to the tractor seat.
I am no anatomy expert so I don't know where I am cutting off blood flow or pinching a nerve or what ever I am doing. I have checked all around the edges of the tractor seat and I am not making contact at any of the edges of the foam. I am not keeping constant pressure on the knee braces so I don't think they are teh problem. Help!! Comments on similar problems and how you solved them will be appreciated.
