standing in a yak
http://www.canoegear.com/html/ check out the pontoons for a kayak. I don't stand in mine, but installing a set of these for the same reason stabilty when standing and moving around the yak.
They say 35" from the rear of the back seat and I am getting a new hatch put in in the rear to accomadate the bases for the bar. Its a neat system and you can put the same unit on your canoe.
Hobie Quest Fisherman is the yak I have and Hobie does a great job of backing up the product. I recieved a new yak for a small defect in the one I had. The reps work well together so getting it replaced 1200 miles away was possible.
Have a good one

Excuse my spelling and grammar, I hooked Mondays and Fridays to either fish or hunt.
