Question Replacing Running Rigging

I'm looking for suggestions for the type / size of line to use for halyards and sheets on my Morgan 321. The main is full batten and uses mid-boom sheeting. The jib is about a 125 RF. For now I do not have an extra down-wind sail - genaker / spinaker, etc. I am definately a cruiser not a racer.
Rig dimentions are: I=41.5, J=13.25, P=36, E=12.0
Your input will be appreciated,
Duke

I'd go with T-900 3/8" from New England Ropes for the halyards. You could probably use the same for the sheets, but it is a bit pricey for use as sheets, especially if you just cruise... I'd go with 7/16" or 1/2" StaSet for the sheets. The T-900 is good for halyards particularly, since it is a very low stretch, high strength line. If the T-900 is too expensive, then use StaSet-X for the halyards, since it is lower stretch than regular StaSet.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Well, I don't have a Morgan, but I just replaced mine with 3/8 StaSetX for the halyards and 1/2 " endura for the sheets

He's cruising and has no need for Endura for the sheets.. Why did you go with StaSetX for the halyards, instead of T-900. I would have gone T-900 for the halyards and left the sheets StaSet or StaSetX... The low stretch is far more important in the halyards IMHO.

To be honest, I was figuring there's more stress on the sheets than halyards, but if I'm wacked on my thinking, let me know, and why

Yes, there is more force exerted on the sheets than the halyards as a general rule...but if the halyards stretch, it will affect sail shape much more than if the sheets stretch, since the sheets are constantly being adjusted anyways...while the halyards are not.

If your halyards stretch, the sail starts to bag in strong wind conditions, which will exert more force against the halyards, and stretch them more than would light wind conditions, it will be more difficult to keep the sails flat and de-power them. In the same conditions, if the sheets start to stretch... you won't even notice more likely than not.

This is why wire halyards were popular, and why high-tech, low-stretch lines are so popular on racing boats. Also, the high-tech lines, like T-900 or Endura braid are generally lighter and stronger than their polyester analogues like StaSet or even StaSet-X. Using the high-tech lines means you can often go with a smaller halyard, reducing weight aloft a bit.

For example:

3/8" StaSet-X has a tensile strength of 5500 lbs. 4.5 lbs/100'

8mm T-900 has a tensile strength of 7300 lbs, but is both lighter and thinner than the StaSet-X. 3.2 lbs./100'

8mm Endura Braid has a tensile strength of 7000 lbs, but is lighter than the T-900 at a slighty reduced strength. 2.7 lbs/ 100'

Does it make sense now??

Finally, it is generally easier to replace sheets than it is to replace halyards. So if you have stronger halyards, the chances of them breaking is smaller... if you break a sheet... you generally don't have to go aloft to replace it...

Personally, Sta-SetX would not be a choice for sheets -- way too stiff. It's fine for halyards (all my halyards are Sta-SetX) but there are too many better choices for sheets that handle better. YMMV of course.
