using 1X7 galvanized EHS for rigging?

[cwa]

Is there any reason not to use 1X7 galvanized EHS wire rope for standing rigging on a sailboat?

I've been told it is acceptable by using a "fisherman's splice" (parceled & served) for terminations.

Also is there anywhere I can get the formula for determining the inertia moments for both boat & mast to make sure that all is sound in that respect?

Thanks,
Carl

Hello,
Thanks for the plug, Tom. It is true, you can get the basics on mast and rig design from the "Apprentice". Not much there about 1x7 standing rigging, as I recall, though. The short form is that it is the wrong tool for the job. 1x7 was evolved for low loads, high corrosion-resistance, and cheapness. The high-strength model is closer to sailboat requirements, but I have found it to be far too elastic, and a bear to work with. Galvanized 7x7 is more in line with your needs. Unfortunately it is so very hard to come by in this country any more. Galvanized 1x19 is even better, but now I'm just dreaming. So that leaves either finding a source of 7x7 that isn't rendered wonderfully expensive by import fees, or going with the best deal on good 1x19SS you can find.
Fair leads,
Brion Toss

Thanks for the info.
I'll look into the 7x7 galvanized now.
I just got your book (about half read at this point) and it is great.
Full of very useful info as we go through the process of building & installing our mast & standing rig.
