Please check your turnbuckles. I think I copied the numbers from the
spec sheet, but according to Max Soto, the numbers are wrong for the
turnbuckle sizes. Again, as I said, check your own boats fittings
carefully. These guys were in production for many years and have been
around about 30, so things change.
