Rigging a boom vang

My old Bristol 27 has never had a boom vang (AFAIK). I have one to install, but, two things occur to me.

1) On the B27 the boom is really low. And I think my main may even be cut a little too big. So, there the boom is only about 18" from the mast plate (the boom is about 10' long). Is this enough leverage for a vang?

2) I have a sliding gooseneck. If I vang-down when off the wind will the upward pressure of the sail on most of the boom just make the boom pivot around the vang, and force the gooseneck down?

My Pearson 26 was without a vang and the boom is probably about the same height off the deck as you describe. I get plenty of pull...works great. Secondly, I don't think your gooseneck will drop because the luff of the sail keeps that from happening.

Red face Re: Rigging a boom vang

I installed push pin sail track stops above and below the goose neck to limit travel. The distance you quoted sounds about correct and I can tell a huge difference when I installed the boom vang on my little boat. The boom behaves now as I wanted it to and I can get the main flat and adjusted.

For the vang itself, have you checked out Garhauer?
