I am thinking about building a 20 ft long carport for my pontoon using either 1.5" or 2" pvc. Just for the frame (legs/joints/etc) i'm looking at $165 for 2" pvc and $110 for 1.5" (schedule 40).
1) Will 1.5" be good enough, or can/will it warp over time? Should i stay safe and just go with 2"?
2) I've been contemplating options for covering it. Obviously i could throw a 20 by 20 tarp over the top (preferably 24x20), but good tarps at a decent cost are hard to come by, especially ones that last (under 100 bucks). Is there some other type of roof system I could make that I could remove when I take it down in the winter?
The boat is moved and covered by itself in the winter, I just want something so i don't have to take half hour covering and uncovering when we use it. I will anchor the 6 legs most likely in 5 gallon buckets with some cement, or somehow connect to cinderblocks. I am in the brainstorming phase so if you have any ideas let me know.
I have looked at car ports and anything within the 3 to 400 dollar range all have a tarp system that goes to hell, and is usually cheap metal or chinese made stuff, so thats why i'm thinking pvc. Plus i can disassemble mostly for winter time. I still have to figure out how to connect temporarily instead of pvc cement, maybe just using self tapping screws in the joints?
