tension on a spin

looking at 100' of line to run my spin halyard on my 30'. Is 5/16 @1800lbs stout enough? oddly he rates his 1/4 poly double braid at 2000 lbs....or should I bump it up to 3/8 at 4400? I used the 3/8 on the main/head... but knowing the sheer size of the spin wondered if i should consider less/the same/or even more of a load factor....

thanks

I would use the 3/8 or larger just for the ease of handling factor.

something like 5/16 warp speed would be fine though a bit expensive.

tommays will become famous soon enough
The spinaker haylard is no big deal as its not controling sail shape like other haylards

The sheet and guy become the place to spend you money as if your reaching and the pole is close to the headstay it becomes a constant problem keeping it adjusted and OFF the headstay

Normally stretch is the controling issue with halyards. It is less so with a spinnaker halyard but it should at least be considered. The bigger issue with spinnaker halyards is chafe, as their lead changes nearly 180 degrees and they tend to be less stable when flying than other sails. Stretch greatly adds to this chafe problem because you have an unfair lead line that is often moving back and forth across an edge, I generally recommend adding chafe gear (a sacrificial cover or stitched on leather) where the halyard passes through the halyard sheeve. I also tie and stitch the tail on my spinnaker halyards so that I can cut them back as they wear.

For the small price difference, I'd probably get the 3/8" parrellel core polyester. That was what I used on my Laser 28.

For flying the chute on the 9.2 I use 3/8 XLS-Extra. It runs well and works well in the line clutch. I bought the line for under $60 and did the eye splice to a shackle. The line is low stretch, cheep and overkill for breaking strength. The old double braid line was over 20 yrs old and a little frayed by the shackle.
