Under load or in a puff the halyard will stretch and loosen the luff causing
the draught to move aft. The greater the load (more wind) the more stretch,
exactly the opposite of what you want as a racer. On the other hand, for a
cruiser, stretch in a puff will take some of the pressure off the sail causing
less wear and longer life for the sail and allow some spillage of air if the
sheets stretch as well. Jerry C&C 27 V.

I've got the book, one of many, and I understand and am an obsessive sail
trimer. What I don't understand, yet, is what pulling the halyard on a sail
that doesn't stretch do?

Sam,
If you are really interested in this,(and you should be, if you want to get the
most pleasure from sailing your vessel),
find a copy of "sail power".
Halyard tension, backstay,lead position,boom downhaul etc are the gears that
accelerate your boat.
I'm writing on Wellness and Anti Aging now, so find the Book.

Tensioning the halyards on the old sails stretched the Dacron on the bias and
moved the draft forward. It can't do that on the kryptonite one!
A bit more explaining please!

The main difference is that the new sails dont stretch and their shape is
factory engineered.
You will still adjust mail and genoa halyard tension according to conditions.
You will likely
not ever require a Cunningham ever again.
Have Fun.

Meant to put this as an aside on Sam's thread. New main and #1 on Koobalibra
C&C115 this past summer. The difference between these and the 6 year old sails
is like high tech winter tires to bald tires in a snow storm ....

Subject: Stus-List Halyard Tension
Reading the tread about halyards, and an earlier post about furlers reminded me
to ask a question of you racers out there: -
I don’t race - only because there’s no-one racing on our lake. Although I have
done a couple of Swiftsures.
But I like passing boats and hate it when boats pass me!
My boat has been pretty well upgraded with all rope halyards; new adjustable
genoa cars; self tailers; new traveller; barbour haulers; and new Dacron sails
5 seasons ago.
I sail with a 135% genoa on a furler. While sailing I adjust the genoa halyard
regularly to move draft in the sail as the wind changes. (I do the same with
the main too!)
Now the question:
Late this season I bought a new high tech, Kevlar, carbon, kryptonite, 135%
genoa.
I’m assuming I don’t adjust halyard tension with this new sail as I don’t think
the sail will distort like a Dacron sail.
Similarly, when I buy a matching main, main halyard and Cunningham adjustment
will become redundant. Am I correct with this assumption?
If this is correct, are there any trimming adjustments with these new high tech
sails that I should become familiar with? Do you trim these newer sails any
different than the old Dacron sails?
What new techniques do I need to absorb?
Thanks,
sam :-)
