Bivi Riggin Guide

+ +

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.

+ +

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.

+ +

There are two essentially-separate jobs: +

    +
  1. set up the +water-collecting tarp
    2. , and +
  2. set up the main tarps
    3. +

+ +

If there is any chance of it raining soon, start with the water +tarp, as you really don't want to miss it, and +setting up in the rain is rubbish.

+ +

Terminology

+ +

I will describe things as if standing at the bottom entrance looking +up, because that works for all three sections. So the +left wall is the +gear/stove/animal-hole wall. The 'back' is the top end of the bridge. +The 'front' is the main entrance.

+ +

Water tarp

+ +

Main roof tarp

+ +

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'.

+ +

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.

+ +

Start by rigging + +

So start by opening it out to full width on the wide central +bed-shelf. and pulling the RH edge
