I don't have a PA so not sure my setup would work in your case but i'll share to at least give you some ideas. I bought a couple of the harbor freight bike lifts and they work great for my revo, that is with a couple of modifications. Here is a pic of my revo hanging in my garage.
So basically i just put up a couple of 2x6's between my rafters and mounted the bike lift to them. Here's a pic of them.
There are a couple of necessary modifications to make the bike lift work for a yak due to the increased weight. You will need to replace the cheap plastic pulleys with higher quality metal ones. I found a couple at home depot and they were pretty cheap. I also replaced the rope that came with the bike lift with some climbing rope.
Another thing I did to make lifting the kayak easier was buy a second bike lift and mount another pulley to one of my walls. This really helped and putting my kayak up takes less than a minute. Here's a pic of this pulley.
If you have any questions just let me know. I hope this gives you some ideas.
