I don't believe there are magic lengths.
There are however lengths that are decidely non-magical, and if you want
something that works on 40, 30, 20, 17, 15, 12 and 10, there are many
lengths that are non-magical.
That's why I did not ask "what is a good length?" There is a pretty
good reference here: http://udel.edu/~mm/ham/randomWire/
Short of buying a 100 foot tape (or a longer one), what methods do
people use to reasonably accurately measure 53 feet (or 72 feet, or 136
feet)?

I think the only important measurement is that it avoids being near a half
wavelength on any bands. Are there really "magic" lengths to be used with
9:1 xfmr into a tuner? I'm skeptical.

Only a bit off-topic, since I have a KX3 w/tuner and a 9:1 balun to go
with it.
I know how to trim a resonant antenna to the correct final length. I also
understand why truly "random" wires don't necessarily work.
The recent post about shipboard operations near Antarctica said they're
using a 53' wire.
How do you guys measure an antenna like this? I assume it can be a few
inches off, but....
