a regular hammock is just the opposite, forces go end to end, and all seams run end to end (hh slit, eno seams) nobody uses a side to side seam in a regular hammock, putting an end to end one on a bridge is essentially the same thing. am i wrong here? seams don't ever handle stress well if the forces are running perpendicularly across it do they? seems like there will be problems particularly where forces are concentrated, like where you sit an read for example.
every bridge hammock does have end to end seams where the fabric meets the webbing, but this is different because it's a curve, which spreads out the force over the whole seam where a straight seam does not.
this is just my understanding of the concepts, i'm interested to see other's take on end to end seams in a bridge, or side to side seams on a regular style hammock.
The seams in the bottom/side of the JRB Bear Mountain Bridge Hammock are fully double lapped and double needle sewn with tex 90 waxed poly thread.... they are not comming apart...
FWIW this new thread is three times stonger than the tex 30 poly threads commonly sold at sewing stores.... the recently available wax type means that it is even more impervious to moisture and eventual rot issues.
