Hybrid Tarp – Flat/Shaped w1/2 Pyramid Attachment

That’s sort of like mine, except the side panel is permanent rather than zipped on and extends about 3 feet from the center, zipper down the middle:

60 inches tall, the left side is 9 feet x 4 feet rectangle, #5 zipper (I’ve tried #3 before but it failed after a while)

Great idea.  I have been wanting to do something like that for along time.

Can you post a more detailed closeup of the peak?

I assume you just start at one corner and zip it fully on or fully off?

Thanks

Yea Ben , the attachment zips all the way off with a one way separating zipper (#3 YKK). However, the next tarp I make like this I’m going to use a #5 two way separating zipper instead.

I negotiated the peak by curving the zipper around like you see in the pic.

That leaves a little bit hanging out, but I’m going to sew a tieout to it so I can use the attachment to cap off one end of an A frame pitch if I choose. A lot of thread and seams in one area. It doesn’t look pretty with the seam seal applied, but all is very solid.

I came up with this (below) to support the pole. I sewed 1/2″ wide polyester (2 layers) around a 2″ X 2.5″  piece of nylon to create a pocket. Then sewed that to X Pac. Next I sewed the X Pac onto a bonded reinforcement. There again, not professional looking, but strong (I’m open for better suggestions). I couldn’t go for an all out wedge because I wanted the tarp to retain its flat tarp function. The pole can also be tied onto the tieout. That means the attachment stays INSIDE the pole though. Or if it’s clear and I don’t want to use the attachment I can just use the tieout to support the pole.

I went through a lot of trial and error to get the attachment dimensions to work out Ben, so if you decide to make a tarp like this just have me e-mail you a diagram of the measurements. Will save you lots of frustration.

That’s a very interesting solution. Thanks for sharing it.
