Rig a tarp ridgeline

Grab first

• Rope and a tarp with its instructions
• Two sound practice posts with permission to use them
• Short tie cords if required by the tarp maker

Before you start

• Use this for a light tarp only, never to support a person or a hanging load.
• Keep the line and tie cords out of walkways. Lower or remove the setup when you finish the practice.

The steps

1. Choose a low practice span

   Use two permitted posts. Keep the line within reach from the ground and leave space below it to spread the tarp without blocking a path.

2. Tie the first end

   Take the rope around the first post and tie a bowline: form a small loop, take the end through it, around the standing part, then back through the small loop. Snug it.

3. Make the tensioning loop

   Toward the second post, make an overhand slip loop in the rope's long standing part. This is the temporary loop used for the trucker's hitch, not the anchor loop.

4. Tension and finish

   Take the free end around the second post, through the temporary loop, and pull gently. Hold the tension and tie two half hitches with the free end around the line below the loop. Do not crank it tight with tools.

5. Add the tarp and take it down

   Drape or attach the tarp according to its instructions. Check that its ties and the ridgeline do not cross a walking route. When finished, remove the tarp, release the tension and untie the line.

Common mistakes

• Using the small slip loop as the fixed anchor. The first post gets the bowline.
• Leaving the tensioning end unsecured after pulling it tight. Finish the two half hitches.
• Stretching a line across a path where someone can walk into it.

Practice together

Dad points to the fixed loop and the tensioning loop while the kid traces the free end on the ground. Swap jobs before hanging the tarp. If the knot is hard to identify, remove the tension and compare it with the source animation.
