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
Any thoughts on my idea and the size of line?
