Line for a Preventer

[mestrezat]

I'm fabricating a new preventer for our 46 foot sailboat. I tend to lean toward using 1/2" three strand line to give it a bit of stretch factor when the wind tries to move it when it is engaged. I'll be attaching it to a large eye strap at the end of the mast and then leading the line forward along the boom to a cleat so all I have to do is grab the line and lead it forward to a block or cleat to keep the boom safely in place no matter what the wind does.
Any thoughts on my idea and the size of line?

I run 1/2" three strand as well. I have two horn cleats that are much too far forward, but I don't want to put any more cleats in, so there you go. Works like a champ. Being able to undo it in jiffy can be important.

Instead of a strap eye (which can pull out) what about a spectra wrap?

I don't think you can have your preventer run too far forward and I think half inch 3 strand is good.

Nylon or polyester could be just fine.
