Best line for Spin halyard?

[shadowboxer]

What line that would be suitable for the spin halyard would be the least likely to kink and jam at one of the blocks. We have had a bad kink jam at one of the pulleys and mess us up on both the spin launch and take down recently.

You may find a line that is "less likely" to kink than that supplied with the boat, but rope being rope, it will still kink! (I think sailing ropes are manufactured with a devious mind built into them just so they will kink and frustrate the hell out of the sailor!)

Our mitigation strategy to lessen the problem when hoisting is to pull all the slack out the line via the aft-most block on the floor, and then throw the loop out the back of the boat so that it drags in the water (done on the last beat to top mark)

There is a thread about this at http://forum.viper640.org/index.php?topic=1468.msg14081#msg14081

Basically it says to up to 5mm or 6mm at 85-88 feet long.  Class min is 4mm.  It will be less likely to kink but you'll still have to ensure it can run.

I replaced my spin halyard and debated on the size also. Went with 6mm FSE Robline.  I am glad I went with the larger diameter.  We will have an occassional kink or knot, but it is way better than it used to be with the stock halyard.  The "feel" of the line on hoists and douses is much nicer.  No problems with how it runs.  As mentioned by others, nothing is magic.  You still have to toss the extra line aft or a couple loose loops in the sock.
