View Full Version : 5 sided Tarp - Prototype 1! (Pic heavy)

I found about 30 metres of silicon coated material (not sure 100% what!) but it's light and the best thing was, it was only 50p a metre in a discount material warehouse. Being silicon coated, the water just beads on top.

My partner then set about making me a very nice 5 sided pentagonal tarp - I'd seen some on the web and they looked to be very versatile.

1st time out today, and we may have to rethink the 5 sided aspect. I don't know what the angles on the commercial 5 sided tarps are like, but mine doesn't touch equally on all 5 sides. Infact, making it into a 4 sided pyramid shape made all 4 sides peg down really well.

I experimented with various openings, having 4 points pegged down and leaving one up as an awning. I didn't erect it under a tree so couldn't tie it all up (and it was in the park, and I was supposed to be pushing the kids on the sledge!)

Managed to get free buckles from the local outdoor shop (Chevin Trek) and the webbing was about £2, so all in all, for about £10 I have something usable and unique. Now to try it out for real!

If anyone out there has a commercial pentagonal tarp - what angle does each side make at the top?

Good stuff particularly like it in bottom pic, useful size and shape.

Liking that too. Use in the bottom config during the day and if (when) blowing a hoolie and raining drop the front down for more weather protection. It's a nice design. goodjob

Ditto the last post.
BTW where did you get the material? I'm not far from Otley myself.
Best regards

Have a look in army surplus shops, i bought some decent aluminium tent poles in 18" sections at £3 each, they'd be great for supporting your tarp and alot stronger than that bendy pole. i use mine for supporting a parachute as a sun shade.

I like that, very practical.

If the tarp is a regular pentagon the angle would be 72degrees between each radial.
I like the idea, it looks brill.

The angles are 72 degrees, but it doesn't pull tight across all sides when anchored as a pentagon. I'll have to play around with it some more - maybe try different length poles in the middle, or suspend from a tree so I can experiment with heights etc.

The material is from a shop called "The Shuttle" at Shipley, and it really is pot luck what is in there. http://www.yelp.co.uk/biz/the-shuttle-shipley

can you suspent it from the center like a parachute? if so that's a good selling point!
Do the edges all reach the ground it looks like there's a gap all the way around?


goodjob obviously very well made! looks a bit nippy inside though!

It can be suspended from the centre. Haven't tried that yet though.

All the edges do reach the ground - I didn't peg it out fully as the ground was frozen and I didn't have enough pegs to do this properly.
Hopefully going away in 2 weeks so will erect it properly then.

I have a hooped bivi, so this is really just to provide a bit more shelter

Wouldn't that be 108 degrees? The angles of a pentagon add up to 540 degrees not 360.
