Yep, tworunners are required. You can only set the one on the windward side of the mainsail
, so if you need to tack or gybe, you release the runner in use, bring the main across and then set up the one on the new windward side.
And yes, you can use low-stretch line instead of wire.
And yes, some mechanical advantage will be required to get enough tension in them. Many cruising boats in your size range use a two or three part tackle, or lead the tails to a winch
, or both. On our semi-bendy fractional rig we have a 3:1 tackle leading to Barient
27 secondary winches, through Lewmar
clutches, and it seems to be adequate.
As usual,Bob PErry's advice above about the belt and suspenders approach is a good guide line.
Again, good luck with it.
