Only since it was sold to me, giving me that impression that it would float. Desiring lighter line that wouldn't absorb water for light wind, downhill sailing. It will do for that....potentially, but I like the thickness of my 3/8 dbl braid for a grip. This 7mm is an amount skinnier.... like 5/16 or slightly less so.Unless you plan on your sheet doubling as a flotation device, does it matter if it floats?
I think the trouble is trying to quantify a value with the word 'More', as in
"More buoyant than a rock." Perhaps you can use it as a Dive-Line?
Good thing with the hemp is if the regatta doesn't go well you can smoke your lines and feel better quickly.I looked up the Father of all ropes Hemp.
