[C320-list] Tuning Hood jib furling (thanks) How high can you point?

[jpmesa at aol.com]

I tried some of the ideas this weekend and it looks like it was the halyard tension was the main problem. Hood also told me to check the halyard tension first.I flopped all my halyard end a few month ago and I lost all my old my old setting marks.  The telltale have always flowed nicely and the adjustable jib track has had good setting from the racing day. I was just hoping to point a few degree higher which I seem to get this weekend. Most of my boats (8) over the years have had hank on sail.  But as my hair has turned gray a good furling jib has made my life much more comfortable. Speaking of pointing higher I'm curious how high others are pointing in the group and I'm not talking about pinching? Thanks JOHN    Holokai  2

Alan-That is a good suggestion.  I was looking a the sailing dynamics and 
their influences on the variouls parts of the luff. A twisted foil would be 
fairly easy to see even with the headsail flying, but probably easier with 
the sail removed.

One other possibility is that the furler foil is twisted along the forestay. 
This can happen if, for example, you get a halyard wrap and apply 
significant tension to the furling line (twists the foil since the top of 
the foil is fixed and the bottom of the foil is rotating with the furling 
drum).  I would sight up the foil slot next time there is a still day at the 
dock and you can completely unfurl the head sail.  This issue showed up on 
my pre-purchase survey and the fix was to have several sections of the foil 
extrusion replaced.
