Here is where I have mine placed for lake fishing. A double strap Scotty on the right front and a homemade PVC holder attached to a rail on the left rear. The only time the front one is in the way of rowing is while shipping the oars. Then I have to dip the oar a little to get past the holder. You may just need to put yours out a little farther in front of you. I have mine closer to my ankle than my knee. A double strap type might be better for that. To get it tight, cinch it up with the tube slightly deflated. Then top off the air and it will tighten right up.
