Here's my set-up, an awning track pop rivited to the lower lip of the hatch and sunbrella fitted with a bolt rope, also lift-a-dot fastners to keep in place. the same for the aft cabin, I also have a clear cover for the main cabin that keeps it bright and still dry and warm. track and fastners are available from Sailrite or your local canvas shop.
The covers serve a dual purpouse they keep the UV off my varnisher weather boards.
