I was recently reminded of the unsubstantiated accounts of men having to resort to a night spent sleeping hung over a rope, as mentioned in this piece about The twopenny Hangover.
"... two ropes, ’bout six foot apart, and three from the floor, which goes right down the room; and the beds are made of slips of coarse sacking, stretched across ’em..."At first, I wondered if this was describing a multiple hammock design, such that each sacking/canvas ‘bed’ was attached to ropes at the head and foot ends, perhaps with multiple canvasses side-by-side along that parallel system, hence the reference to the ropes being 6ft apart, which is the length of a bed. In the morning, the beds being being 3ft off the floor, the proprietor could easily move under and along them to untie the knots (at the foot end?!) via a simple slip knot as I also very much doubt they would have cut the expensive rope. The clients then would fall to the floor – a rather shocking start to the day! The ropes and 'beds' could then be easily fixed back again for the next customers. Also, the canvas could be easily removed and replaced if damaged in any way. However, even this idea is doubtful as to support the weight of possibly four men per length, the knots must have been pretty substantial, ditto the brackets to which they were fixed. I am therefore of the opinion that these rope beds were merely single hammocks as per on a ship, the three foot from the floor allowing for the sag of the hammock.
