Does it have really large 'holes' in the weave?
I generally refer to those as the Mexican Hammocks because I see more of them sold by the vendors in Mexico than anything else. Usually have a thick rope/cord weave with holes in the weave large enough to get your hand through. My experience with those hammocks have been very hit and miss. I haven't figured-out exactly what to look for in them yet.
Time for another trip to a Mexican beach...for research.
