How to rig a rain tarp without trees -- poles, maybe??

LS, sorry to hear about the hospital!! I'm trying to rig up a really big and high rain tarp, like they do in the Northwest. I am trying to create a dry area over a picnic table, with room to do chores. The photo at the beginning of the thread illustrates the idea -- the tarp is at a diagonal, with the roof line about 8 or ten feet above the ground, and the side "triangles" staked out wide.

The trick is to support one end of the roof line at the trailer (not difficult) and then support a couple of poles way at the other end (not easy). But thanks to the suggestions above, I think I can do it.

Now the only trick is getting to go on a trip, instead of sitting at home.

I'm not exactly clear what you are trying to do. (I spent last week on a surprise visit to the hospital.) Do you have an awning? I know that you both have hiking poles. Got line/rope? You're good-to-go.

Fortunately, Jon, weight and bulk will not be key factors here -- cost is a big deal, as is sturdiness. Our travel plans are on hold, unfortunately, due to some infirm elderly relatives, but someday soon, I hope to try out this tarp idea.

During my much younger days, I built a hang glider using 2024 alloy Aluminum tubing. You can choose diameters & wall thicknesses so that they slide into each other. Very stiff, very light weight, but pretty expensive. I've used left over pieces for masts, etc.

By the way, schedule 80 pipe or conduit is thicker (and, of course, heavier) than schedule 40, but is still both heavier & more flexible than thin wall 2024 Aluminum tubing.

And OR biker, that is a great tip about paracord getting too tight to adjust or release. I can see you've spent a lot of time with ropes! I will try quarter-inch cord instead.

For some reason, knot tying is an extremely perishable skill. Tall ship sailors used to carry "rope and spar" and practiced on their off time. I've been tying all kinds of knots all of my life and can never remember the correct one when I need it. Now, I have an app for that. ;)

Buss, very helpful -- thanks!! I am saving the videos for later in the day, after the chores are done. (Am I the only nerd in the world who prefers watching "how to" stuff on YouTube instead of regular TV?? Maybe . . . . )

Must be at least two of us :-)

This is an example of the diagonal setup I am talking about, with a very big tarp:

Dan this is really not that hard;-)

Think volleyball net on the beach.

For poles only you can determine what will be strong enough but I'd guess that 2" schedule 40 would work. with 3-5 feet being the common cut size to give you a 8 - 15 foot high post using coupling to join, actually a couple of 3' couple of 4' and a couple of 5' should give you most common sizes you will need 8-10 2" couplings and you should be good to go.

You will need a few stakes (10+ -) that are fairly substantial -

Figure the location of the post, drive stake that is straight up and down that the 2" schedule 40 will fit over the add 2 more stakes on 90 degrees, to hold the pole up.

Set one pole.

Pull line to next location.

Set second pole just like the first. If needed, run the connecting rope to a new stake in the ground, on both ends.

Connect one corner to the Trailer's back side, so as to not drip on covered area.

Now either add a shorter third pole or pull tarp's last corner, to a new stake in the ground.

Any size necessary will work.

Use this Knot to pull all the stakes tight. Look at the 4 minute mark.

If you ever need any help - the Grands can do this in the living room every time they get together, they always want a new fort.

Enjoy the RAIN - but I enjoy the Awesome pictures you share with the SUNSHINE and Blue Skies.

Hope this helps,

Ken, I am impressed -- you sound like you have actually tied a Prusik, and until today I had never heard of such a thing! I would probably use paracord for the Prusik. (I always carry a duffel bag full of various kinds of rope and cord in my truck, so I will experiment.)

The paracord might have a hard time coming loose when you are done. I like braided nylon cord. 1/4" or 3/8" would be better.

1/2" or so for your ridge rope. The para-cord should work for your guy lines.
