Rope shrinkage from splicing

[Brion Toss]

Hello,
We've been working on developing such a chart, but it varies according to brand, as well as diameter and, near as I can tell, the phase of the moon. So for now the best practice is to mark your tail, mark the circumference of the eye, and then beginning at the eye circumference mark that is farther from the end, measure some arbitrary distance -- say, 4ft, and mark the standing part.
Splice in your eye, and then remeasure the distance to that last mark; it will be less than it was, by the amount of shrinkage that the splice causes.
Fair leads,
Brion Toss
