Re: Boat Cover leaks?
Keep in mind, any low spots the water can pool in, too. The faster the water runs off the cover, the better. So, you may want to have something under the cover keeping it from sagging.
I thought I had a pretty good set up made of PVC last winter. But, we got more snow than usual and it didn't support the weight. I found myself with a 100# slab of ice where the water pooled. Only thing I could do was wait until it warmed up enough to start the ice melting. Then when it was floating in the puddle on the cover I broke it up into managable chunks and pulled it out and drained the water. COLD!!! Unfortunately, I had several gallons pooled on the floor and frozen, too. I propped the cover back up, better, and just had to let everything melt and drain/evaporate off. This year I'll build a heavier frame that will keep the cover peaked.
