OK, so I've been giving some thought on how I could help a heavier person enjoy hammock camping.
My thought is to do a bit of a mod to a HH Safari to make it easier for someone with mobility issues to get in/out of.
I'm thinking about getting a Safari deluxe...bottom entry. Then take a pair of six foot loops of cordage...even just paracord, although a thicker, easier to grip rope might be better...and running them out through either end of the hammock through the same route as the ridgeline, and looping them out over the end of the hammock.
I'm also considering making a little velcro "slide" to run them through so that they stay up along the ridgeline, but are easily accessible to someone who might struggle with sitting up in a hammock.
The idea would be that someone with mobility issues could sit down in the bottom entry as normal, roll back in, but then reach up and grab that loop of rope and use it to pull themselves up into position along with pushing with their feet.
Similar idea for getting out...keep the loop to the foot end on the ridgeline 'slide', and they could hopefully reach down and open the bottom entry with their toes, reach up and grab that rope, and use it to help pull them up into a sitting position, rather than forcing them to use their ab muscles as much.
