Poll about gybe preventer - when do you use one?

I was wondering when everyone uses a gybe preventer. I was using a line from the boom to the bow and back, but got out of the habit. Now I'm thinking of installing a gyb'easy.

In the case of this poll, a preventer means a line securing the boom, or relocating the boomvang to act as a preventer.

Re: Poll about gybe preventer - when do you use one?

I have a split rig and if the winds are piping on a downwind run, I usually don't have the main up if there's a risk of too harsh a gybe. I'd rather have twin headsails or one with the mizzen. Take care and joy, Aythya crew

I only use one when sailing wing-on-wing. Then it's vang to the rail as a preventer.

I too, use one when sailing wing on wing, but only when it is choppy.

Re: Poll about gybe preventer - when do you use one?

Always I use a kicking strap to stop the boom from swinging. The kicking strap goes from mid boom to one of the scuppers.
My ship is a cutter and that boom is long, and if it rides and swings across, it will crash into the backstay. It happened once, at night, and it was not something I'd want to repeat. The ship was caught aback, and needed the motor to recover.
In heavy airs, I don't even risk doing the gybe anymore, but instead "do a granny" by swinging the ship right through the tack instead. It's bumpy, and slow, and noisy but the boom will not swing aggressively.

Re: Poll about gybe preventer - when do you use one?

On customer boats I rig a preventer any time apparent wind is behind the beam. Always.

On my own boat I'm a little more relaxed but not much. I've been through more crash gybes (four in a single event) than I care to think about and it's worth the time to scurry forward and rig.

sail fast and eat well, dave

Re: Poll about gybe preventer - when do you use one?

I have two small but strong dyneema lines permanently rigged on the boom. When we're in choppy seas with the wind pretty far aft I just take the line on the leeward side of the boom and secure it to another line I rig from the bow. Quick, easy and makes my life less anxious, especially if I have a relatively inexperienced helmsman on the wheel.

Dutchman boom brake, wouldn't leave home with out one. In fact, I think they should be standard on every sailboat.

Re: Poll about gybe preventer - when do you use one?

It depends.

Most boats I sail do not have boom brakes, but I really like them.

I go wing on wing only when I have to. I prefer to broad reach and gybe.

Coastal waters, flat seas - do not use one. I pay attention to the foresail as soon as the clew drops I head up a little.

Blue water - a boom end preventer rigged to the foredeck back to the cockpit.

I would never use a kicking strap / boom vang as a preventer; that is not its purpose.
