Hello Listers, Does anybody know the forestay length of a 30 MK I as it came from the factory, with the rig properly tuned for 8” of mast rake?
By geometry (square root of I squared plus J squared) I’d expect it to be in the neighborhood of 41’3”. I is 39’ for a 30 MK I, and J is 13.5’. According to the owner’s manual the forestay cable is 1/4” and the lower fitting is <quote>1/2” jaw to jaw turnbuckle & toggle</quote>. On mine, the cable is swaged into an eye fitting on the lower end, which is pinned to a turnbuckle screw that’s probably 1/2” jaw to jaw (if that’s what’s meant by the owner’s manual). The screw at the other end of the turnbuckle is identical, and is pinned to a toggle that’s pinned to the bow stem.

I’m wondering if this is the standard from-the-factory setup, and what the overall forestay length is from pin at masthead to pin at bow stem, when the rig is properly tuned.
