Mike .
Made the dodger as well as side curtains for my Cackler out of Sunbrella , Material is good stuff , but i think i would try to go with something a little more durable , Mine has been in service for about 3 seasons and shows no sign of giving up but i wish that it was thicker . I tried to sew it on a regular machine but you really need the comercial machines to get thorugh multiple layers of the canvas . the color is all the way through . my cover is really never exposed to the weather i store the boat in a garage when not in use . Good luck with your choice !!
