The plastic over the wire is not a permanent/factory installation....the
boat's original owner must have decided to put them on for some
reason....maybe to reduce chafing on the bimini...you can buy these
coverings by the foot at most yacht shops...you just pry them open to
fit on and off. He also put a piece on the babystay.
The plastic coating(s) were removed few years back when I had a North
rigger inspect the standing rigging...no signs of corrosion anywhere on
the rigging....they can be removed and put on easily as they are split.
The backstay is #8 Navtec rod but the split is too high above the
cockpit to measure with the Loos RT10.... so I measure the two wire(s)
tension....I adjust the turnbuckles until the gauge reads approx. 500
lbs. each and assume that means approx. 1000 lbs on the single rod.
It probably doesn't work that way but that's the way I have been doing
it for 15 years and the rig hasn't come down yet.
Maybe I should tension the rig and get hoisted to measure the SS rod
....and when it is showing 1000 lbs without any added tension from the
adjuster, measure the two wires (without the plastic wrap).
Advice?

Not sure about your question, but the plastic coated wire for a
backstay would scare me... Be sure to check for corrosion.
My 35mk2 manual states 2200psi i believe as the maximum pressure, and
there is a chart which shows what tension this equates to. HydraTech
tensioner, made in Vancouver. Mine is now holding pressure again, but
I have no mast to attach it to at the moment...
