well the front and aft curtains are less than a year old as they were replaced and the side curtains were the older components. But one fateful day coming back from fishing I left the front and sides on and the one sidecame un snapped and started whipping in the wind and before I stopped it was just enough to crack the brittle plastic. the same thing happened to the other side but not as bad. I broke out with the duct tape and fixed em up. I got a quote to replace both sides at $150, but not something I got around to doing as I only use the enclosure in cold or rainy weather and for now the $0.99 duct is doing a pretty good job lol. But I tell you what this is the first boat I've had with an enclosure and it's awesome. It's amazing how much it helps in the cold especially for the fall striper run in the bay.
