[quote=wlrottge]Those things are a pain; I'd fix the tack to the spin pole and use a piece of spectra as a halyard. You can rig the purchase for the luff tension any way you want; single or double blocks on the forestay, or use a single block on the forestay with a 4:1 down low (you need more purchase than you realize).
This also fixes the problem of moving the tack and therefore slightly changing the sheeting angle.[/quote]
