Winter Tarp with Asymmetric Doors (Membrane SilPoly

[GadgetUK437]

Was looking to get a winter tarp, with doors, that would pitch right down to the ground (when necessary), to cover a 11' hammock.
I reckoned I would be able to get it out of 8 yards of RipStopByTheRoll's Membrane Silpoly.
And, if I used a cutting plan like this,

I could get maximum doorage with zero waste.


Joined like this,

to make this,


Thought it would be a good plan (whilst waiting for my package from Kyle) to make a prototype in Polycryo,

Reckon I made me a useful tarp there too! (and light),


The Membrane Silpoly version was going to be a bit heavier, but I was gunning for sub 400 grammes,


Used RipStopByTheRoll's excellent Winter Tarp instructions,

and made my very first flat-felled seam (ridgeline),

The SilPoly was very slick, pinning (a lot) made things considerably easier).

Still squeaking in under 400 grammes, before seam sealing and glueing the panel pulls on,


The panel pulls were sewn to Ripstop nylon circles which I then glued to the outside with SilNet.
Some weighty reading matter holding the circles in place,


Detail of ridgeline tie-out, note the shonky sewing,

Hems were done with the rolled hem foot on the new (to me) Pfaff machine, which was exciting!

Final weight is 402 grammes, blew the target by two! I blame the over-enthusiastic seam sealing and overly large reinforcement on the panel pulls,

(14.18oz)
Of course, the weight will climb when I add guylines and snakeskins anyway.

And here it is pitched to the deck (storm mode),
doors folded flat on this end,

and a lil' more pointed on this end,

And the view from the master bedroom,


Here are the final dimensions, thanks to Kyle's generous 8 yards, I was able to go a little longer, and give it slightly larger doors,

I made it with the longer doors nearest my head and feet (right-hand lay), therefore more coverage in those areas when in porch mode.
The only wastage was a half inch tapered sliver, I took off to square things up.

Just need to have some rain to test it, and wash the talc off!

Nice work, looks like you have plenty of space in there too.

Youre stitching is top notch. Thats a beautiful tarp!

Very clever! I'm impressed.

That's awesome.
I have my supplies to make my winter tarp and can't wait to get started. I like the idea of building a prototype out of something that may actually be useful. Polycyro...never heard of it. Is that from home depot or something? Is that just a fancy name for plastic drop cloth?
I bought my supplies from diy gear supply and was going to use those plans until I realized the detailed work that went into the plans from rsbtr. Wow. I figure I have a lot more planning to do now.

All I can say is wow

.

cross-linked polyolefin. (Gossamer Gear call it Polycryo).
The easiest source is secondary glazing film.
Have a read through this thread,

I put up a link or two in there somewhere.

Wow good work! I have been toying with the idea of doing something similar.

First outing into the wild... well, 10 minutes walk from my house!



Was planning to hang a hammock for a snooze, but got caught up playing with guylines and ran out of time.
