Hoping to skip some learning curve steps on setting up a preventer on the CD30C.
I tried running one from mid boom to bow cleat, then back to cockpit, but the angle is too shallow (strong winds will still swing the boom). Was thinking next attempt would be run a line from bow cleat, through chock (with chafe guard), to a snatch-block. Then run preventer from end of boom, through snatch block, and back to cockpit.
I would rather not connect the preventer to a stanchion ...
Any advice, empirical or experienced theory, much welcomed!! I feel more stress than necessary when @ broad reach right now. Would like to run with the wind more than I am able to now

Re: CD30C - Setting up a preventer
In mild conditions I will take the boom vang to a stanchion base.
In heavier conditions I have a bail on the end of the boom, with a line that I keep in place, which runs up past the mid point of the boom. The line is there so I can always reach it and move it to either side of the main sheet tackle when I want to rig a preventer. The line is three strand nylon so it has a bit of give. I have been using a small block and tackle clipped to the 3 strand and a stanchion base. This means I have to go forward on the lee side to adjust it so it is not ideal. This year I am going to use a block on the stanchion base and take it back to a spare winch in the cockpit.
I am not sure why you are reluctant to use a stanchion base for this purpose. The ones on Raven are rather beefy, well fastened and in the right location to do the job. In fact, they are probably stronger than your boom. Raven's old boom always had a very slight bend in it. After may last Bermuda trip where I really cranked down on the preventer by tightening up the main sheet, I had a more pronounced bend. Remember, I would have had to go up on the side deck to ease the preventer and it was nasty. There well absolutely no issues with the stanchion base.
Raven now has a brand new boom and I will run a longer line back to the cockpit. This will not only make it much easier to adjust but will also add more length to gain some more stretch. It will still have a loop in the middle and a longer piece shackled to it so I can more easily move it to either side. The other option is to have a preventer permanently rigged on each side.
I will still use the stanchion base for an anchor point, Steve.

I may be underestimating the strength of the stanchion for this purpose. A block on a fw stanchion has been very tempting, and makes this an easy exercise.
I just didn’t want to cause a torqued stanchion base / crack glass at the deck. I honestly didn’t think they’d take the load for anything over 10kn gusts (i tend to be conservative on assessing these things by instinct .. lol)
