Review on Affordura Support Straps Adjustable Canvas by Kevin Shimmens

I just received my order and installed a support system under the boat cover. The product itself appears to be well made and was easy to use. The only thing I don't like is the use of water bags to hold the support post. I live in an area where it can be well below freezing and I didn't think about it until they were filled and installed. I'm probably draining half the half water to account for the bloating? Sand would be a better choice for colder climates. Otherwise I like it.
