I put a bail on the boom about half way back. The clip on the preventer line goes from that, forward to a snatch block on the rail just in front of the shrouds, and then back to a cleat mounted on the cabin top. In my opinion, the preventer is to prevent a swinging boom, not to stop one. When going down wind, the preventer goes on and holds the boom in place so it never gets loose enough to swing with any force.
So far, so good, for 20+ years.

The vang is too close to the mast so all of the force on the sail will result in huge leverage forces. I've heard of broken booms as a result. The ideal is to use the main sheet eye so long as you can get enough of an angle on the preventer line - as close as perpendicular to the boom as possible.

I've been thinking for a while about installing permanent preventers or a boom brake on my 30. In the meantime I attach a preventer, when I think it's required, to either the mainsheet eye or to the vang attachment. This week, as I was moving the preventer, we were overtaken by a rain squall which resulted in a nasty gybe. Nobody was injured, but it scared me into rethinking my preventer. Our boom has 2 eyes: one at the end, where the mainsheet attaches and the other about a third of the length from the mast, where the vang attaches. I'd like to make a third attachment for a preventer or boom brake about half way along the boom, but I don't know how to do it. A bale, I think, will not withstand the lateral strain of a gybe. A friend recommended a T-ball fitting, but it also is made to withstand strain from one direction only, I think. Can anyone recommend a fitting that will attach to the boom and withstand the strain of a forced gybe? Also is there collected wisdom about preventers vs boom brakes, etc.?
