Proof of concept...

We are enjoying our little pontoon boat.  One thing that is a real chore with it: putting the factory cover on it...

It's a good design - it holds up to the wind and rain.  It has specially designed clips that hook into the railings on the boat.  Same material as the bimini.  It keeps crap (literally and figuratively) off the seats.  But, it takes me at least 20 minutes to put it on... and I need knee pads to crawl under it to put the posts in there that form the peak.  You need the peak to shed water.

If we are using the boat most days, we just leave the cover off unless big wind or rain is predicted.  Joan was thinking about what would work for light duty and still be fast to put on or take off.  I suggested a tarp, and she said, "I don't want one of those ugly blue tarps on there - that would look tacky."

True.  After thinking about it a bit, she said, "Do you think a rain-fly would work?  Something light weight that we could just hook in the corners."  Before ordering material and putting grommets in it, and sizing it to fit, she found a reasonable size on Amazon.

It is very night weight.  Waterproof (but that isn't a big concern, because if heavy rain is predicted, I will go with the factory cover).  With bungees, it hooks in seconds...

The bimini keeps the sun and birds off the back part of the boat.  Joan made a helm cover a while ago that slips over and cinches with Velcro (works great).  We were just looking for something to cover the front seats.  I would call this one a "proof of concept," and consider getting something a bit wider and longer.  I have a kit for attaching snaps or grommets, so we could put them exactly where it would fit the best.  This rain-fly was less than $15, and will be functional for the time being.

Easy!
