Russ, when using a SOT on standard roof racks always carry them deck side down with the hull in the air. This will prevent deforming the hull. To illustrate this, I am around 4 minutes walk from the water. One day last summer when my cart was broken I threw Katana on the roof of the car and took her down to the beach. On my return trip I slid her on hull first but didn't flip her onto her deck as I only lightly tied her down and figured she was only going to be on there for a few minutes.
As soon as I got home the phone rang. I went to answer it and then got sidetracked. I went out a couple of hours later and the hull had two huge indentations in it where it was draped across the racks. Remembering what I had once read on US forum how if the plastic gets hot enough the hull goes back to its moulded shape, I left her lying on her deck in the sun with all of the hatches closed and luckily she went back to the way she came out of the mould. I know never carry her hull down on standard racks.
