Hi,
I wasn't able to do it. 1.82m and 70kg. I let you translate it in stones and feet... Ikea bag is a useful multi purpose tool: righting bag, drift anchor and the bag to bring your wet clothing home. Knot the righting line to the mast step and the bag at the rigthing line... Hardest job is to come back on board, however.
Cheers,
Klaus
