    Somewhere around 25 ft should do it for each leg but the lateral force on the tripod leg is going to be huge so it would definitely be bowing in at the attachment point.

    You would be better off with 2 16' horizontal members supported by 3 shorter vertical poles. There are a few pictures of such a rig somewhere on this site from many years back. I think Tom Hennessy has proposed (patented?) something similar using a series of equilateral triangles to support 3 or more hammocks from a common structure.

    Long oars such as those in the diagram were not uncommon a hundred years ago, when rowing vessels of 30' were in use. The total length of an oar was 1/7th the inboard portion, multiplied by 25... so for a vessel with a beam of 8' the oars would be over 14' feet long.

    I like the teepee idea... how about a prairie travois that converts into a hammock-stand-teepee; the polygonal tarp would provide a five foot overhang, so you could walk around the whole teepee under shade. It would have a hole in the center so you could build a fire in the middle.

    they would need to extend from one to the other.... That's as precise as I can get.
    I may be slow... But I sure am gimpy.

    We should do that some time at one of the hangings.

    Maybe I can get some friends to help me try it out in my backyard!

    Yes it can be done. Our scout troop did a zip line using a tripod as the upper end. The zip line went across the tripod and then was anchored in the ground. the lower end just went staight to the ground. We actually had multiple hammocks hanging off the legs during times the zip line was not in use. Poles were right about 22' long and approx. 10" at the base. They were cedar.
    On a previous trip they had two tripods set up and just ran some rope from tripod to tripod. (double line - one for safty harness and the other for pulling yourself across.)
    The kids had much fun building them and running the zip line for the younger scouts.
    I will look for some pics and try to get them posted.

    Found some: I think these were taken at Klondike 2008
