<h1>Bivi Riggin Guide</h1>
<p>Every year some poor bugger who has probably never done it before it
gets to rig the tarps and be responsible for any soggy miserable
nights that might result if it's not done well enough. Starting from
the bare space it's really quite hard to know where to start if you've
not done it before, so this doc attempts to provide some advice.</p>
<p>Note that this was written after Wookey+Joe's rigging effort in
2014. It is not necessarily optimum, but did seem to more-or-less
work. Feel free to imporve it over time.</p>
<p>There are two essentially-separate jobs:
<ol>
<li>set up the
water-collecting tarp</li>, and
<li>set up the main tarps</li>
</ol></p>
<p>If there is any chance of it raining soon, start with the water
tarp, as you <strong>really</strong> don't want to miss it, and
setting up in the rain is rubbish.</p>
<h2>Terminology</h2>
<p>I will describe things as if standing at the bottom entrance looking
up, because that works for all three sections. So the
<strong>left</strong> wall is the
gear/stove/animal-hole wall. The 'back' is the top end of the bridge.
The 'front' is the main entrance.</p>
<h2>Water tarp</h2>
<h2>Main roof tarp</h2>
<p>This is one large tarp covering more than half of the internal
roof. There are two main cross-ropes to hold it up, ties at the back
edge and 'knitting' to reduce sagging in the almost-flat central area.
The objective is to get it taut enough and square enough that almost
all the water runs down the top and out the front not collecting in
'buckets', which then drip. That means that it has to be fitted quite
'flat'. </p>
<p>Start with the big green 10x10m tarp. It seems to be near-enough
square so don't worry which way round you start. The basic position is
that it goes all the way to the right wall, partly 'underneath', and
the left hand edge is about in line with the steps up the middle. The back
edge lines up with where the roof rises at the back entrance.</p>
<p>Start by rigging
<p>So start by opening it out to full width on the wide central
bed-shelf. and pulling the RH edge </p>
