I don't think so. If you build a good pvc support frame to handle the snow, tarps work fine. You do have to get out there a clear snow when it's the wet stuff but it's not a big deal. I have a 22ft. CC and a 27ft. Downeast Style in the yard right now under tarps. A few years back the local boat yard quoted something like $300 to shrink the 22 footer. I bought a 30 X 40 heavy duty trap for the 27 and have got 2 winters out if it, $65. You do have to keep your eye on things, water in the bilge will wreck your boat in the winter. If you can't keep your eye on things then shrink is proboly the beast bet. They can install vents to keep the the inside dry.
Cheap can work but there are other options -- usually better as well. It's all a matter of circumstances and what you want and are willing to pay for. I think that's called supply and demand. If there was no demand there would be no shrink wrap (except in electronics).
I keep both my boats on cape cod in the winter. There is usually not that much snow. I tarp every year and put supports inside the boat.. it works very well.. There is no real rocket science to any of this. The tarp is not air tight, so venting takes place. There are plenty of people out there to serve the boating industry and perform any function that you want ... for a fee. If you dont have the time, then pay someone for it.. If you are like me, I like to do whatever I can for my own crafts, and I make as much time as possible for a hobby that I love...I do, however, pay a professional to winterize the powers.. I like the professional scrutany for any potential problems... and, hey, my marina guys have to make a buck here and there...
