Rigging gybe preventer

My boat has a wooden toerail. Where can I attach a block to rig a gybe preventer? There are two spring loaded blocks on the genoa track but they don't appear to be substantial enough. I can see how to rig a snatch block to a stanchion base but that would lead to deck damage. Thanks.

Re: Rigging gybe preventer

I just disconnect the bottom of the vang tackle and reconnect it to a stanchion base. You can install some pads but you arn't likely to make them any stronger than a stanchion base.

Do you have a pad eye on your foredeck? A preventer led from the boom end to a block on the pad eye and back to the cockpit is far better than a toe rail or stanchion point.

Using the vang is an invitation to a bent or broken boom.

Re: Rigging gybe preventer

I tried using the Dutchman system and was never able to properly use it so I just sold it. My cabin top is too high, and I would never be able to have any tension on the line for the Dutchman thing to work. I am now looking at possible solutions. It's hard without pictures. I really don't understand most of the explanations I find on how to setup a preventer. It still baffles me and it's something I have to figure out before I head out to the Caribbean.

I really like boom brakes. Too bad your did not work out.

Good diagram. Iffy spelling.

Re: Rigging gybe preventer

Make sure you use quality parts. I was doing an off shore race on a boat that had a Chinese part (can't remember the part though) that broke leading to a "Chinese gybe" and oddly enough I was warming up some chicken fried rice on the cooker at the time. What are the odds?

I remember now - it was a snap shackle.

Why do you think a slotted AL toe rail would be bad use?

Re: Rigging gybe preventer

I've said it before but, be sure you use enough line to let the boom over, for when you gybe not if. This might be the "Chinese Gybe " Scott refers to.

The "modern" toe rails which are screwed into a plate lack the necessary strength. An older one, though bolted, might work but I have seen them deformed; that might compromise the hull deck join.
