Mark,

I dont know how much it weighs exactly, but my fishing partner has a newer model with an alum. frame and his is noticeably lighter. But its still light overall and easy to move around.

The slow leak is air escaping at the valve. I have not taken it apart to repair, I simply inflate and then tighten the outer cap down as normal and its air tight. You can hear the air with the cap off and I am guessing it would affect things if you did not screw down the outer cap.

I'll be around thru Tuesday nite then out of town thru Sat nite.
