This discussions seems to be a reiteration of the "Of Cotter Pins and
Rigging Tape" article by Bill Seifert in the July issue of Cruising World.

In this article Bill states "Never tension a turnbuckle that's under
load." I know Bill as I used to sail out of the same marina, and he's a
very knowledgeable guy. However I hate rules that have no explaination
behind them. Why would Bill state this?
