Importance of forestay/backstay tension?
So we've been trying to get the furler working that came with the boat. It's the style of furler designed to work with a hanked-on headsail. I forget the name of it... Marine something?
Anyhow, we are having problems with the top bearing not wanting to turn unless the forestay tension is adjusted down (using the turnbuckle) to less than 50% of its original tension. The internet discussions I've seen about this furler say that this is a common issue.
Now, there's a boat of the same type a few slips down, and the owner leaves his forestay LOOSE - I mean visibly sagging - when not sailing. He pulls his backstay tensioner to tension the forestay for sailing.
So my dad is thinking we can do the same. My concern is that we dont know much about rigging, just what I've read on here, which seems to say that a forestay should be tensioned to about 15% of breaking strength. If we loosen it up that much, will the backstay tensioner be able to add enough? (masthead rig). What will this do to the balance between between forestay and backstay tension?
We dont know, I guess, if the rig was tuned correctly to begin with, but the boat sails well and in balance. How concerned should we be about changing stay tensions just to make the furler work?
