I've been paddling my Necky Phantom and I had an alarming problem the
other day. During the paddle, I had a tingling sensation in my legs,
similar to when you foot "falls asleep". After a 45 minute paddle, I
tried to get out of the kayak and my legs were so numb, I almost
couldn't stand!

A little background: I removed the molded seat and put some thin foam
on the bottom to lower my center of gravity. It does not feel
uncomfortable when I paddle.

Any idea what's going on!? (aside from jokes about rowers learning to
paddle....)
