Question using preventers question

For downwind sailing a preventer is supposed to be a good idea to prevent the boom becoming lethal in an accidental jibe. Can anyone tell me how to rig one properly ? Can a take the boom vang and hook it on the rail ?

I'm sailing a tall rigged 31' sloop, that carries a good sized main.

Thanks, John

One Approach

jmencel:

From what I've been taught, the best way (especially for extended periods & rolling seas) is to secure a line to the end of the boom....then take the line forward on the side you intend to ease the boom......to a turning block at the bow......then bring the line back to the cockpit on the opposite side. ......take up the slack as you ease the boom...............then cleat off the preventer line so that the boom cannot gybe accidentally.

That line can be used to control the boom on a gybe in conjunction with mainsheet..............then re-route the preventer once the gybe has been completed.

From what I understand, using a preventer at mid boom to the nearby rail runs a much higher risk of damaging the boom and/or boom vang.

Here's a sailnet article on the subject:

You would be better to attach it to something more substantial like a midships cleat. The farther forward you can get it the better the lead will be. When I jury rig a preventer I usually just throw a mooring line over the end of the boom and up to a forward cleat. Maybe your boat has a toe rail? Lots of options. Use your best judgement and you will be fine.

Instead of a preventer, I use a Dutchman Boom Brake. I think it makes a bit more sense, especially if you're sailing short-handed or single-handed, as you don' t have to go forward to switch it over.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

An Example

J:
I have read about the boom brake but have not occasion to use..............I have used the line forward & it works fine........but I can see how the brake could simplify. Some boats are much easier than others to handle the mainsail & gybe.

Decided to take a peek again...............here one set-up version

Be Safe & have fun no matter what..........

Just another data point. On a Cal 25, we frequently use an old vang as a preventer running from mid-boom to a padeye forward of the mast. While racing along with a chute in about 20 kts at 2 AM, we were a little by the lee, but didn't really want to deal with a jibe at that point. We knew that if we could just get by a pier, we would be eased up and all would be well. Well, guess what, we took a wave off the pier; it pushed the bow around and we jibed with the preventer on. That is to say, the forward half of the boom jibed. The rear half stayed right where it was as the boom bent in half. Ouch.
