[Public-List] Main Halyard.

[Lawrence Morris]

I have to respectfully disagree.  All rope is the way to go.  The 3% stretch figure is at maximum working load. A 3/8" halyard is loaded at 25% to 35% of maximum working load.  The stretch is imperceptible to negligible in my experience.  There is no need to go to exotic materials in an all rope Halyard.  I have had standard sta-set X on my boat for 12yrs without any halyard sag issues.  It is safer for the crew and cheaper than a wire/rope spliced halyard.

It depends upon what you do on your boat and how much money you want to put into line and the change,  and how much you value sail shape for a reasonable cost. Check out the prices and stretch of the line that you think you want to buy for a halyard. You will need about a bit more than 70 feet if you use a winch on the mast and about 10 feet more if you lead it back to the cabin top. If you have 3% stretch on that line, (3 feet in 100 or 1 foot in 33'),  then you will have about 12" of stretch when cleted on the mast  and almost 16" when cleted to the cabin top. If that amount of stretch is OK for sail shape differences, then go ahead, otherwise consider staying with wire which does not stretch that much.  UV does not do much to wire and it does age line. Personally I think halyards with 1% stretch are too expensive, and any more than 1% is not good enough to maintain sail shape. I have had the main halyard last more than 15 years and am sure I would have replaced line halyards in that time due to UV wear and chafing from use. As it is , I have rope tails and have replaced them but there is no stretch below the winch, and even if there were it would be on less than 1' of line. I can cope with up to 10% there.
