Over the weekend I borrowed a Loos RT10 and tensioned Persistence at
similar numbers to Equinox for lowers, intermediates and uppers.  The
head stay was much more difficult as it has what I believe is a Harken
Mk2 Unit 1 furling system.  With this system the furler itself is the
turnbuckle and you do not see the threads as they are internal on the
top of the furler but you can see the bottom exposed threads.  When I
attempted to shorten/tighten head stay the upper locking nut would only
turn 1/2 turn and then seize.  I believe this is because there are no
more threads and is as far as it will go on the end of the rod.  The
lower stud that threads into turnbuckle and pins the forestay had
approx. 3/8 inch of thread remaining or enough for two full turns.
Accordingly I unpinned forestay and turned the stud two turns and then
reattached.  This is now the maximum I can tighten forestay.  Note that
I also will increase tension with backstay as needed

I am wondering if this could be a function of the mast butt placement
and mast rake.  What is the typical measurement for mast rake?  On our
J27 was approx. 15 inches which was measured distance between the main
halyard and mast at cabin top. =20
