Dean, I had a cover on our C&C 36 and have a cover on our 37+ made by Topshop in the Kingston/Quinte area. The ribs are aluminum conduit. I use zip ties to keep them in place with the snow load on the life lines and toe rail. The ribs can twist with the weight of heavy snow. They are built to allow water drainage but may need another set of ribs if you get pooling. On the 36 I had to use a piece of rope to bridge a gap in the conduit. You will need to monitor and see how it is. Best if the cover is tightly fastened from below. The 37+ had a new canvas last year and sheds water and snow very well. My advice is to check it often until you have a level of comfort and deal with any pooling. The new cover is a mast up version and fits well. I installed a garboard plug on the 37+ and have less to worry about. Good luck with yours. Len Mitchell Crazy Legs 1989 37+ Midland On.
