Sunbrella Winter Cover

We have a 30ft. Catalina standard rig. Does anyone know anyone who makes a full cover for her. I've looked through different sites but they only seem to make sail covers. As a standard rig surely someone has a design for it. Or can someone direct me to where I might find specs on the boat including measurements. I've done my own measurements but wondered if someone has them or has a cover available. I was going to make my own but if I can buy one then I might go that route. Familiar with Catalina direct and a few others.
