Question about

[Summer]

We have a 1982 Bristol 35.5 - ours for just over a year now.

Trying to measure our rigging with a Loos Tension Gauge model B rated up to 9/32. We cannot fit the gauge on our upper standing rigging wires, which we believed to be 9/32. When measured with a caliper, the uppers measured .290 (which is about 19/64? is that even possible?). The lowers measured accurately at .250.

Questions -

Is it possible our upper rigging is a different size than we thought, or is it possible it somehow swelled with age/ needs replacing?

How do we find out what the appropriate wire size is for our boat? We are wondering if perhaps the uppers are oversized?


Any insight/information/suggestions are much appreciated!!
