But there are gathered end whipped end hammocks that will support up to 400 pounds. Is it just the stress on the spreader bar or is it something else?

Just a guess, but I would say it is because some gathered ends are double layered; while the bridges are single.
no clue if that is accurate
a gathered end hammock is one single piece of fabric bunched at the ends, so the weight limit is how strong the fabric is mostly. A bridge doesn't really have that luxury of being one piece of fabroc, instead it will have a bunch of seams, especially jrb's. That added with the lightweight spreaderbars, and you have to watch the load....
yup, a ge uses all the fabrics width, and therefore most of its strenth
I think it has to do with the spreader bars. Since the bars will be taking the weight of the hammock occupant and companies don't want their product failing with people on it they rate the hammock to the bars. That's what I suspect.
My guess:
The hang angle is less and that increases the overall tension on the suspension AND the hammock.
The way I look at it is that a gathered end distributes the weight across the fabric and transfers this directly to the suspension. A bridge hammock distributes the weight to 2 anchor points on each side. thus narrowing the weight down to the strength of those anchor points. You then have to deal with the spreader bars which may or may not be less then the anchor points. It is a system as like a chain with it only being as strong as the weakest link. My guess is that its the stress placed on the four anchor points. I will say that I have been in a older JRB BMBH that I got used and mainly was used by my 10yo son. I had slept 10 or so nights in it and I am still alive. I could see the stress on the anchors but it was nothing I would have had an issue with. I weigh 275. As Sgt. Rock says " your going to die..."
My wife and i have built a few and the main issue is the spreaders and the fabric.. i wiegh alittle over 350 lbs and i can bounce around in my bridge all day and feel safe,, a few tips
1 - use the .742 spreader bars, what i did for extra security was i slide my spreaders into a piece of pvc that is just one size bibber so it fits snug,,, no way its gonna fail
2 use 1.9 70d ripstop and double layer
3-= use 5/8 mule tape in your cat cut and roll 3 times and triple stitch ( check out grizzly adams videos)
4 Make sure your suspention dogbones are the same equell length as the spreader bars
My spreader bars are 42 wide at head and 40 at foot
This will hold over 400 lbs easy
This is a close to what you request that I've found: http://www.dream-hammock.com/ComfortRating.html
