| Jun 4 at 23:03 | comment | added | Tom | I think your math is wrong: it would be proportional to the weight of water equal to the volume of the body, not the weight of the body. An anchor does not have to display its own weight, but the weight of the water it displaces. | |
| Jun 4 at 23:01 | comment | added | Viki | Regarding the part about anchor, sadly, I believe the math in my answer still applies, so you should only be able to pull yourself in if you are able to climb a rope with some extra weight (about 60 % of body weight for 180 cm tall person, a bit less if you are taller). The key is, the forces are different than with regular diving, about the same way as it is super easy to dive to the bottom of an inflatable pool, but really hard to meaningfully push into its side. | |
