Pendant Rope Sizes

[Jack Sparrow]

One thing that I find interesting is that no matter the size of the rope, the ratios, for example A|B, are constant. so knowing the information for one rope diameter, it is possible to calculate the block geometry based on these constants.
I honestly don't know how the blocksize calculation that you mention was done.

Very nice discussion on ropes and rigging. I've learned a lot. Thanks Signet! Magic Mike
