I have had problems righting the blade solo, weigh 165 or so. Need some wind to do it. if there are only very light winds I can't get it back up without using some type of aid.
I am 150 (68kg) and can right it solo unaided with the aluminum rig only if it is blowing around 12 or more. I can right the carbon rig myself in any condition.
To be safe when sailing solo I do now always try to carry a righting bag just in case.
