This reply is coming to you very late, but you or someone else might find it to be of some use.
For the first time since owning Finesse (hull #33), I decided to haul her out for the winter. She "lives" in Seattle and I try to sail in the winter, but I just don't get out much during that season. I am in the process of having a custom cover made by Power Steering and Marine Specialties in Costa Mesa (949-548-6978). They made the interiors and a lot of canvas accessories for SLM, in the day. Bob Baltierra is still working there, and I had him make new canvas for my mainsail cover and dodger, as well as new interior cushions and custom curtain for the V-berth opening. He made the original canvas and cushions on my boat.
Anyway, Bob will make me a winter cover this month (Jan 2017), and we are in the measurement coordination process at this time. I made a custom poop deck onto my boomkin, but the rest of the boat is like any other FC22. After Bob is done, he will have a good pattern for a FC22 winter cover.
BTW, Bob has already made several all-year covers that look more complicated, but they look like very good covers for boats that are in the water.
