Re: Boat Cover for Winter Storage
Not sure where in west Michigan you are, but we've been known to have massive snowfall also, but usually it melts in between blizzards.
You didn't say how big a boat you've got. That could make a big difference.
If you look at TD's pics, his PVC is braced to the gunwales of the boat. If you've got a lot of snow load, not sure if they'll hold. So... here are some other thoughts as you design your own system.
The PVC will work, but I'd suggest vertical supports at least every 3'. For the heavy wet stuff in W Michigan, support every 2' might be even better. The inverted 'V' support TD shows is ok -- just use more of it. However you frame it, make sure the side / vertical supports won't slip, slide, or bury themselves in soft ground. Try to support the tarp over the boat to prevent weighty issues on boat components like the windshield, steering wheel, throttle, etc.
You will want enough tension on the tarp cover to prevent sagging and puddling from heavy snow, ice, and water as they melt.
You will also want to allow some kind of air movement inside your tarp canopy to prevent a place for mildew to start (see other threads in this forum). It's probably a trick how to do that AND make it weatherproof.
There are other threads about winter storage of your boat and trailer... many guys recommend blocking the trailer up off its wheels. Others mention varmint-proofing your boat over winter.
Search this forum, get your ideas, make your plans, and let us know what you come up with.
I guess I'm quite fortunate. We store our boat in a garage at the lake cottage over the winter
