5.3' x 13' diy tarp
Weighs 12.5 oz
Started off with 66" wide sil.
Tried it in asym without a ridgeline, it rained a lot and a little too much flop in the top, filled up with about 5 gallons of water in the tarp hanging down in my hammock, but nothing broke or ripped. Thought it was ruined though until I set it up like this.
Still have to reinforce the tieouts.
Nice. I did a shorter version...probably with the same fabric.
I get better coverage using it as a rectagle, but your longer length might solve that. Try it with a continuous rigdeline for support.
Be careful where you place your gear on the ground. I put my shoes where I normally would and as a result, they filled with water. Learned to tuck them under the hammock.
Yes I figured out your gear on the ground has to go directly under the hammock.
I have not tried an asym with a ridgeline. After it filled up with water I thought it was ruined and figured Asym was probably not worth it since it is so narrow on the one side.
Yes better coverage as shown.
Reason for the 13' long is I have a 12' long hammock and wanted a bit extra coverage and 13' is the perfect length to make one of these ground setups but longer. I experimented with several lengths a few years ago and 13-14' is perfect for this type of ground setup. You probably dont notice them but there are tieouts at 1.5' in on one the long side. That forms the 10' back then the corners are tucked in leaving you with a 10' x 5.5 deep x 4' high pyramid. Works better with a beak but its big
Just something to consider...Knowing that silnylon stretches a bit when wet, I've started running a length of guy line under the ridgeline of my tarp so that in heavy rain when it does sag a bit it doesn't do it in the center and hold water like you mentioned. costs me next to no weight or effort. It also helps a bit with a taut pitch as well.
