Changing the halyard from wire to rope
I'm new to this fourm and I have a question, but first some background. We sail out of Whitby, ON on an H28 Ketch rig. She has a mahogany hull, spruce masts and a furling headsail.
Our wire halyards have all but worn out and we've decided to switch to rope. The sheaves will take a maximum of 3/16"
It was suggested to us that we go with Spectra 12 strand because it's low stretch and high strength. However it's very expensive, approx. $1.30/ft. It has a Minimum Tensile Strength of 3600 lbs.
Novabraid Polyspec has been made as a less expensive alternative but I want to make sure it's strong enough. It has a similar elongation at break strength but only a Minimum Tensile Strength of approx. 1800 lbs.
Does anyone know if this is suitable as an alternative?
Thanking you in advance,
