    Draped loosely over a ridgeline.... but I can change that with no problem atm...
    in fact... I'll go play....

    I think the zipper tape is shot amongst other things. It was salvaged out of an old tent and if I remember right come to think... it was causing problems there too.... but I'm not positive ablout that it was so long ago that we used that tent.

Since I'm in no hurry, I can research this issue at great length and in great detail. Thanks. DTE
    Doug,

    If the bugnet ridgeline is at the hammock knots, then one way to look at the curve for the bugnet is as an adapter of sorts. The horizontal length between the hammock knots is one length, depending on the hammock length and the sag angle of the hammock. For 31 degrees, the ratio is 6/7ths. The length along the edge of the hammock can be shorter than the length down the center of the hammock by the amount of 'ears' pulled or other shortening means. Those two dimensions, the horizontal length between hammock knots and the length of the edge of the hammock, are the two dimensions the 'adapter' is trying to fit. Drawing software programs sometimes will do this math for you fairly simply by trial and error where you don't have to solve any equations... that's what I did.

    Dave, I can't tell you how much I enjoyed your response. Once upon a time I actually majored in engineering...at a time when calculators that would do simple calculations were exotic examples of wonders yet to come...we wore our K&E Slide Rules in their leather scabbards clipped to our belts(I still have mine). To imagine that it would be easier to use "drawing software" rather than equations to solve a "simple" problem just flys in the face of intuitive absurdity. I doubt that I could follow the logic of the string of equations, but I surely can't follow the logic of computers where you press the "start" button to turn the beast off. Nevertheless, I understand what you are saying about the ratio of the centerline length to the perimeter length. However, that doesn't answer the question of shape, does it? I'm not trying to make this more complicated that it needs to be, but it sure is fun!!!! Fortunately, errors in this calculation don't mean the astronauts miss the moon. DTE

    Doug, I pondered about the shape also, looked at several ways of doing it, and just went with the 3-point arc that the particular software I use generated. That seemed simple, clean, and met the loose requirements I came up with.

    You may figure it differently, but my thinking went along these lines. Since there isn't anything holding the body of the hammock to a fixed shape, it is a shape that varies depending on how you choose to lay at that particular moment. Add to that that the center line of the bugnet is able to slide over the ridgeline from one side to the other 'on demand' and you have so much flexibility with the bugnet that there isn't likely one optimum solution.

    Speaking of slide rules, I used my older brothers 2nd or 3rd hand Post Slide Rule with a fine leather holster.

    Thanks Dave, That's acceptable logic...there is no absolute answer, except that a perfect solution is one that keeps the skeeters off.

    is anyone impressed that I could multiply two one digit numbers on a slide rule as long as I had enuf tries and already knew the answer... No? Not impressed... I didn't so. I wasn't either. Now my dad used to be able to use one of those things. That's why I try to work on a project using the material rather than numbers. Some times you eat the bear and sometimes the bear eats you. My latest bugnet project was an example of the bear eating me.
