Title: Halyard size
Post by: ghebbns on May 28, 2013, 04:49:11 PM
I know the manual suggests 120 feet of 3/8ths line for the halyards (I have a tall rig).  My contact at North Sails is recommending 7/16 if I go with SLS polyester or 3/8 with gale force spectra.  Thoughts?  If I go with 7/16ths will I have issues with the sheaves in the mast?

Thanks,

Greg

Greg : You can upsize your halyards, but you need to talk with North and find out how bendable the upsize is going over a 180 and 90 degree sheaves!?!

I went to 7/16" halyards and the only down side I've found is that you need to winch more sail to the top than I had to using 3/8" line.  The plus is you never have to be concerned about strength vs. wear.

Something to think about.

I went with 3/8"/10mm and have been happy with it.

Greg,

I agree with Ron, go with the 7/16", stronger and better feel in the hand. All my halyards are that size, no problems but you will have to winch up the genny to the top...Jeff

Thanks for the replies.  Am I missing something?  I don't see how the diameter of the halyard would impact how much sail you have to raise??

Thanks,

Greg

The thicker the line the more it resists bends.  So as the sail goes up the sail track the combination of the weight of the sail, friction in the sliders and the resistance make it harder to hand pull the sail up.  So what Ron was saying is he can hand pull it most of the way, but the thicker halyard means he has to use the winch earlier to finish raising the sail and get a proper tension.
