    Using the 4 side measurements and the alpha angle for patent image 18, I back fiddled the rest of the lengths and angles. I overlayed it on standard material. Angles other than alpha not shown but I have them if needed. I can plot any point and scale to any length.



    Here it is overlayed on the actual patent image (in red). I expect the patent image has been distorted or it's not really 41 degrees but rather represents it.



    Here's the same but scaled down and rotated to fit standard material. Long center length went from 103.5 down to 96.5. Easy to double the material but maybe not enough length. I'm only 5'6" but I believe I need 102" min. (76 + 24 +2) . Please correct me if this is wrong. Close up (macro) images of the 4 connecting ends on a HH would be very nice

    How real is his angle?

    Good work. I would want to get out my hammock and look at it. I think it is a little different where the knee side tie out is.
    Is that too much to ask? Girls with frikkin' lasers on their heads?

    This "rolled edge" technique might work on a Speer-type hammock with favorable results. You may even be able to roll one edge more than the other to get an asymmetrical shape. I am going to experiment with this when I get a chance.

    I also noticed something else about the HH that is interesting. The hammock is sewn together for a short distance at the head and foot end. You can see what I am talking about in slowhike's picture of a HH with the net removed:

    This would create a cone effect on each end that is bound to influence the shape a of the HH.

    The more I look at this HH the more I start to realize it would be hard to replicate the feel of this hammock in a DIY version unless you take it apart the HH to see how it was put together. I wish I could find one for sell that already has the netting removed. Then it would just be a matter of unwhipping it and taking measurements.
    I think what you see in the picture is the end of the HH Undercover sewn together and not the hammock itself. I have an undercover and it looks exactly like what's in the picture. It's also baggy under the hammock. If it was the hammock it would be taught.

    Stoikurt, its the hammock material that is sewn here. Its where the bug net is attached giving the bug net its diamond shape. I know, I took a look at my HHULB this weekend. I was doing some modifications to it.

    I just got mine out and looked at it. Jazilla is right it is the undercover shown.

    The rolls in the fabric you are talking about is what I think gives it the open feeling and not bunched at the ends like a normal hammock. They seem to start about a foot or so from the end. I'm going to incorporate them into my last asym hammock tonight and see what happens. I think they give more girth to the hammock, giving the flatter feel then a speer.

    One problem I see is the whipping and holding the ends from coming off.

    I cut the cover off of the ends of my HH. Just a wiretie holding the cover in place. It is rolled and then heat sealed with the sprectra running through the heat sealed ends.

    I'm thinking that rolling the bottom fabric will gather the ends enough that I will not need to fold the ends much more. The HH's fabric does not go to a point. The folding and gathering up of it make it look like one. Hopefully there will be enough seam left to hold the whipping from sliding off. If not I'll add a seam.

    That may be the undercover in the pic but the ends of the hammock are sewn for a short distance, like Jazilla said, it's what gives the netting the diamond shape. If you have a HH to look at you can confirm this.

    A little bit, but not that much. A side note, I just did a quick test. I think I am close to the HH feel with what I was doing before and adding the rolling. I just need to get how much to pull out the edges vs the middle to get the hammock shape without the shoulder squeeze.

    I don't dispute that the HH may be sewn a little at the end to accommodate the netting. But the picture is definately an Undercover. And it's wrong side out based on the corner (right below his knee) where the elastic side tie outs go. Right side out would have the corner up near his shoulder.
