Thats what I meant by 'nominal'. I was told the 1/8" 1x19 has a
larger diameter than a 1/8" compacted wire. Let me google it. ...
<br>
<br>
oops, looks like I'm wrong based on:
<a class="moz-txt-link-freetext" href="http://www.rigshop.com/site_pages/products/standing_rigging/wire.html">http://www.rigshop.com/site_pages/products/standing_rigging/wire.html</a><br>
Just a couple datapoints, ... don't use this for your decision. <br>
says 4mm compacted is ~same strength, 16% smaller diameter and 10%
stretchier than 3/16 1x19 .<br>
says 4mm compacted is ~same diameter, 30% stronger and 24% lower
stretch than 5/32 1x19<br>
<br>
why the stretch and strength differences are not the same doesn't
make sense to me...<br>

under the impression that for a given nominal wire
size the compacted version had the same
cross-section area of steel, same strength, same
weight and same stiffness, but had lower wind
resistance. That way in a pinch you can swap
between the two types without worrying about any
differences in the really important parameters.<br

In a nasty blast a few weeks ago on the Bay,
Carlos' mast suddenly went sideways, outers
parted at the top and inner at the bottom.
Amazingly mast is fine (and so are all the
crew). So I need to replace Carlos' standing
rigging, and someone suggested Dyform or
"compacted strand" wire. They are both SS
wire but pack a bit more steel into the same
diameter (I think) and are therefore somewhat
stronger and less stretchy.<br clear="none">
<br clear="none">
Does anyone have experience with either of
these - or know whether they are legal, for
that matter? For reference, this is what I
see in the current rules (first entry is in
main body, second entry is in checklist):<br
