    Bridge hammock side support

    Is it necessary to utilize the 1/2 inch webbing (or other support) on the sides of the bridge hammocks? Has anyone just hemmed the edges?

    Your definitely going to need the support. If you eliminated either the webbing or Amsteel, you would have to use fabric so heavy that there would be no appreciable savings in weight.

    If you weighed below 120 lbs, you might get away with not ripping it for a short while, but the hammock wouldn't last long IMHO...

    Grizz will be much more scientific in his explanation...

    potential energy = mass x 9.81m/s^2 * 0.5m where mass is what your scale reports in kilograms, and m is meters. Without substantial support on the sides the potential energy is converted to kinetic energy, which is converted into life insurance claims by your survivors!

    Scientific enough?

    Let's try engineering. The principle upon which suspension bridges are built is that the mass of the roadway is transferred to the suspension cable by the vertical connectors, and then the force of that mass being affected by gravity is carried by the suspension cable to the towers at the end points, then transferred down the tower to the ground. The bridge hammock is working on similar principles, with the hammock body playing the role of the vertical connectors, the webbing or cord on the curve playing the role of the suspension cable, and then the force gets carried to the tree.
    The point here is that whatever is on that edge is being asked to carry your mass along it. Without
    a cord or webbing, my guess is that this is like taking an inch or inch and a half of fabric, attaching
    one end to a high up tree branch, and then suspending half yourself from it. Will it hold? depends on the strength of the fabric. In any case if it is nylon it will certainly stretch, and that is suboptimal as well.

    theclark5 I think yours is a good question, if only because understanding the answer helps you understand the way/where forces are balanced out with the design.

    A good laugh before bed. In short... support it is. Thanks Grizz.
