I store my PA in my garage on a platorm lift. Here's a post that shows my setup.http://www.hobiecat.com/community/viewtopic.php?f=78&t=21661
Hobie and my dealer recommended against storing the PA flat on its hull as this could cause derformation in the plastic. They recommended flipping the boat or storing it on its side. As you can see, I store mine upside down so the weight is on the gunnels and the hand rails, which are the strongest part of the boat. My brother stores his outside under his deck. He flips it upside down on a wood patio under the upper deck and runs a thick cable lock through the Mirage drive well and around one of the 6x6 deck posts.
