Not exactly what you are looking for, I know, but these photos may give you some ideas.
These awnings were not designed for winter. We had them made in Hawaii and are typical of the set ups you find there to keep the sun and rain off and make a live-aboard more comfortable. But we now find ourselves in our fourth winter in snow conditions; our second winter in Alaska, and have learned they work very well in snow too.
The set consists of five pieces: one over the bow cut like a narrow triangle with the tip cut off, one large piece abaft the mast, and two smaller pieces enclosing the stern. We have had them up in winds over 40kts and with 18 inches of snow on the docks with no problem. They are made of Sunbrella secured with 3/16 polyester rope.
To be ideal for storage, they should be much lower and have some additional support for the main section but the cut would be similar. This set is fifteen years old (Photos taken Nov 2012) and is still in excellent condition.
Made to set lower, with the bottom flush with the deck instead of the lifelines and with a wooden frame with battens nailed on the outside, this arrangement would be about as bomb proof as you could hope for. Added benefit is that you could still easily get aboard to work
in the cabin.
