What size wire or turnbuckle size on an O'Day 25 headstay? I don't have the boat in front of me to measure. Thanks.

I don't have that data, but will guess 5/16 inch turnbuckle, what's the hole diameter on the stem/tack fitting?

Thanks Dave. The boat is 500 miles away but looking at pictures needs a turnbuckle on the forestay. I've got a 5/16 and just found a 3/8 one so I should be covered unless there are other issues.

Here are the specs for the O'DAY 25 Standing Rigging: Wire diameter is 5/32" and the DWYER Mast catalog that I have listed the clevis pin dia. for the turnbuckle for that size wire as 5/16".


Standing Rigging Specs.


Headstay 5/32” x 30’10” (K/CB)

5/32” x 32’10” (Keel)


Upper Shroud 5/32” x 28’9” (K/CB)

5/32” x 30’ 9” (Keel)


Lower Shroud 5/32” x 15’8 ½” (K/CB)

5/32” x 16’8” (Keel)


Backstay 5/32” x 32’8 ¼” (K/CB)

5/32” x 34’8” (Keel)

All Standing rigging is SS 1x19 type wire and lengths are with turnbuckle (where applicable) closed, from eye to eye (most riggers measure with turnbuckles half-closed, so be sure to note this and/or bring old rigging to rigger to measure for replacement)

Thanks Sunbird. Same wire size as my 23 so I have several spare turnbuckles that should work.
