Having actually done this sort of thing for a living about 30 years
ago, I think there's a better solution than West Marine shipping
things off and waiting for mail to deliver new ones.
If (big if) there is a rigging shop in Pittsburgh, you should be able
to take one of your shrouds into the rigging shop and they can
fabricate a new one in about 20 minutes. The only reason for 20
instead of 5 minutes is the care that they will take in laying out
measurements. The actual construction of the shroud once the wire is
the right length will take no more than 2 minutes.
The one problem will be the availability of the specific end fittings
(turnbuckle on the lower end, T-fitting on the top). Every rigging
shop will have turnbuckles in stock, and almost every one will have a
T-fitting. "Almost". There's the rub, lad.
In Annapolis there are at least a couple of rigging shops in
Eastport. In Pittsburgh, there may be zero rigging shops. By
"rigging shop", I mean a mast builder, though I think in Eastport
there is one shop that does only rigging construction. I can't
remember how far it is from Pitt to, say, Erie, PA, but there is
likely a mast builder somewhere along the shores of Lake Erie. Yellow
Pages, Google, WhitePages, whatever, look for "mast builder" or
"sailboat rigging" with your area code as a field in the search.
Another, somewhat delayed solution: does anyone at SSA have their mast
down at the moment? Would you be willing to detach a shroud and take
it to the rigging shop next to APS and have one or more copies made?
Final note: by "shroud", I assume we're talking about the wire that
goes from the mast to the side of the boat. Not the Shroud of Turin.
That is a whole 'nother question.
