Well after looking at my whoopie slings and thinking that they might be a bit to long. I decided to cut them down a little bit and use the excess I cut off to make 2 continuous loops.
These go through the channels at each end of the hammock and then loop over themselves. They then attach to the whoopie sling via a carabiner which also works as a drop line to keep the hammock and its occupant dry in case it rains.
The whoopie slings then attach to the tree hugger’s via another carabiner. I am tempted to look at a marlin spike hitch for this instead but thats something to do in the future.
