Have a look in your local accessory shop. You should be able to find a grey plastic hanger, comprising 4 hooks, with the end 2 extended into an 'S' shape to fit over the awning frame. Although plastic, they are quite sturdy and capable of taking a wetsuit on each hook.....
IKEA sell long hangers with a hook at each end - about 7 inches long. No idea what they are for (maybe hanging baskets?), but they are perfect for hanging coats and towels from the awning roof.
