A better way to rig your jibe/ Gybe preventer. The best and cheapest way?

- We are all familiar with the preventer, just a piece of rope ran to the end of the boom and around a forward cleat then back on deck. But this super simple idea makes rigging it easier while underway. As the hours go by and you go from reaching, to beam, to broad reach, to running and suddenly you had a preventer on, but don't want to stop the progress. This simple trick makes it a little easier.

That’s a good simple set up, and a good demonstration. Fortunately I have done it that way in the past.
For the doubters, you can just Set the preventer, and in medium winds then sail into the wind and induce an accidental gybe.
That will show or prove your set up is working properly.
that sounds like a fair/safe way to test a preventer rig. good thinking.
What a simple practical suggestion. Never thought of that rigging line under the boom. Thx I’ll set that up. 😊
Glad you like it
This is exactly how it is rigged on (some) traditional ships for a very long time. Thanks for sharing it with the yachting world!
Thanks, I figured it was about time it made a show on youtube.
Excellent lesson!
Glad you liked it!
Great tip! Nice thing about this method is it's so simple and easy to setup. Also, when you gybe it's a very simple matter to swap sides to another pre-setup line to the bow.
True. Our friend also had double lines on the boom, as his main sheet was mid boom, coachroof mounted.
I had been thinking of having two lines set up one each side the length of the boat to have ready as a preventer but this is a much more elegant solution thanks
Glad you like it.
I was taught to tie a line to the end of the boom and take it up to the fairlead at the bow of the boat, but I can see how this would be more efficient. Thanks for sharing.
no problem :)
But that's precisely what this is doing. The smart move is that by the time you get to the point of wanting the preventer, the boom is typically well out over the water, and so this just provides a ready-to-use line already attached to the end of the boom to which you can attach 'an extension' to take to the bow fairlead and back to the cockpit. So you _are_ rigging a line from the end of the boom as you describe, it's just the line is made of two parts ... the static part that is always rigged under the boom ready to use, and the running line you use to extend it around the bow fairlead.
My usual solution on cruisers where the mainsheet is often in front of the companionway, is to rig a line from the mainsheet boom attachment point to the midships cleat and back, which is simply another way to get around the end of the boom being well out of reach by the time the preventer is desirable 🙂
@@iainhunneybell Nice and clearly explained. Thanks for contributing :)
@@iainhunneybell I see that. It’s an excellent solution to something that I didn’t realize I needed a solution for. My way worked fine, but this is much more efficient. I’ve already re-rigged my setup. Already had the eye onboard, so just cost me a length of rope 😁
Agreed @@Skipper12-w4c. We're all used to hauling the boom in to attach a line and trying not to fall in the drink, or my solution of using the mainsheet attachment point when in front of the companionway, but this is a simple and neat idea. I like it a lot 🙂
Just unclip the kicking strap (boom vang) from the base of the mast and clip it on the loop at the base of your lifeline stanchion. It takes 20 seconds and you don't have to sheet in the main or hang overboard.
That’s a fair idea, but on our boat the vang is around 4ft along the boom and the boom is 16ft+. A lot of people recommend the preventer being rigged from the boom end as opposed to the middle because of the forces involved can be enough to snap a boom in the middle. I guess it depends on the individual setup. Thanks for commenting
Yes , specially if the end of the boom goes in the water, if the preventer is mid boom or further forward, there is a biiig chance it will snap in two pieces. At the end as you say is no doubt better 💪🏼⚓🏴☠️⛵❤️@@theincompetentcrew
I've been meaning to rig one of these, thanks for the reminder. Excellent demonstration too.
Took me the best part of last season before I remembered to do it :)
Simple solution to an important safety fix.
That's how it's done, thanks!
All about the simplicity
Thanks for commenting
Simple, easy, sensible and cheap. Thankyou! I'm going to set that up on my own boat.
When I bought my boat, a 1986 Moody 47, the forward fitting on the boom attached to the gooseneck was split in 2. I had to have a new part machined to replace the damaged fitting. I am certain the previous owner had an uncontrolled gybe in a heavy wind as that was consistent with the way the fitting had split. Your idea would have prevented that, so to speak 😂
I guess thats is why the call it so. Sounds like an expensive remake. We can all only hope the small things we do will be enough to prevent damage. Thanks for the comment.
@@theincompetentcrew I had to get the old part, bolt the 2 pieces together, get it 3d modelled into a CAD package to get the fitting dimensions correct, then redesign to be much stronger, then 3 days being cut from a block with a cnc machine. £1500 which I thought was very reasonable given some companies wanted over 10000 to do it. The new part is far better and stronger than the original Hood part.
@@boatsandbits7091 Considering its often a weak point on most rigs I bet it is nice to know if won't fail again. Thats super cool.
@@theincompetentcrew Dude over a 3 year period I have upgraded, redesigned, improved all the boat systems. I have finally finished with a massive steering system replacement. The old quadrant was galvanically corroded... New quadrant with separate linear drive arm, new bracket for the chain sheaves, new cables, new conduit etc. Massive job but now the steering system is superior to when the boat was new. In the course of doing the steering I found 4 separate flaws that each could have caused loss of steering. Although I was originally a physicist I spent the last 13 of my working years repairing sailboats. Cheers
Very good information we are fairly new to this and I’ve tried a couple different variations, but I like your take on this. We will subscribe.
Thanks. Ideally if you do it, run the 2nd part of the preventer back to a cockpit winch and tension when in use. Wish I'd said it in the video. :)
FYI, we always rig a double preventer, one on each side. This does help if you do jibe ( in some extreme situations). I never lean over the side. Our preventer easily hank on a cleat at the mast until ready to deploy. Preventers have saved my rig, I won’t sail downwind without one. I’ll give your suggestion a try too. It’s never a bad idea to have choices.
Seems there are quite a few of you doing the double preventer and its a good idea. You've got me thinking. Thanks for commenting and giving inspiration.
@@theincompetentcrew Its not that hard. I run mine to the mast when not in use. We keep the lee preventer slack until the winward is hardened then tighten up a bit. In port I slack all my lines and hang them on the stantons. Its a quck way to keep the deck clear of line while in port. Fair winds
Nice tip. Thank you 😊
You’re welcome 😊
Yeah. I just heard about using a descender for climbing but I think the line is bette for sure.
@@MultiBmorgan I bet it does work well for some people
A smart solution! Thanks for sharing
Cheers 😁
Just learning to sail and I will definitely set this up. Thank you for sharing. Cheers.
Glad we could post something useful for once 😁 hope you follow along
I have a boom brake and it allows me to sail and gybe my 47 foot sailboat without breaking everything and getting killed. best 600 bucks you can spend.
Nice!! A good investment
Great informative video 👍
Glad you think so!
Great info
@@KristiRich-k9f 😁 glad you think so!
Brilliant.
@@Cptnbond cheers
With modem lines, you have to be careful. The stretch can lead to a sudden move happen after all. The line is long, the angle is wide, leading to 5% stress being enough to get past the midpoint (granted, you may use it in practice inky if the sail is further open).
I've seen it happen on my own yacht, and it's not pretty. Preventers are simple, but can easily lead to bigger problems if done improperly.
That is correct! it was just a quick demo to show how having a permanent line mounted to the end of the boom makes rigging easier when underway. The boom would always be out fully if preventer is on. Line choice also makes a difference. heatset dyneema- 1-4% stretch under load, polyester 5-15% underload, Nylon 15-30% under load. Tensioning back at the winch is a good idea to make release easy if needed. Thanks for adding to the comments. :)
What other way is there to rig a preventer? My boom actually has a loop on the end with the words "preventer only" engraved in it. The previous owner didn't have a preventer on it when I bought the boat, but it had been on the hard for a few years. Splicing a snap shackle onto the end of a line was one of the first things I did when I bought the boat. I just snap the shackle to the toe rail at any convenient spot.
I should probably put a snap shackle on the inboard end, save using that webbing and buckle each time. I remember being told the best mechanical advantage is as far forwards as possible. Some people do like the eazyjibe and scott boomlock type devices but they do cost a little more than just a piece of spliced rope. thanks for commenting
Good advice! Great video
Its always the simple things :)
Yes agreed
Agreed
very cool thank you.
@@MultiBmorgan thankyou
I don’t like preventers because I imagine that completely resisting a gybe could end badly for the rig. A boom brake which slows down the gybe is safer. One can be made very cheaply by using a climber’s belaying ‘8’ purchased for a few bucks from any outdoor sport store, attach to boom at a strong point as far aft as convenient, plus suitable rope led through a block on the toe rail or Genoa track back to a cleat in the cockpit. Tension it when downwind, ease off at other points of sailing. No need to leave the helm to attend to it. A really safe alternative to a preventer.
@@captratty2167 I agree a boom brake can be effective. I would fear a climbers figure 8 would only give enough friction to a relatively small boat though. Eg. The gybeeazy has 4 notches to create friction and is much beefier and even then states don’t use on main sails over 40m2. And always attach as close to the end of the boom as possible, again, mounted half way along the boom doubles the loading. Figure 8s I remember are good to a max of around 1-2kn(climber here, or I was). And as it can’t be pre tensioned(the boom has to swing a way over the deck before it starts absorbing I would suspect the loading by then could be well above its absorbing ability. I am aware some of the older boom brake were held responsible for snapping booms when mounted mid boom. If a preventer is led back to the cockpit it can be released, but also worth noting the load is less as the sail and boom does not travel before the load it taken. Interesting solution though, thanks for sharing
@@theincompetentcrew Thanks, and yes, I have only used the climber’s 8 on a 29ft boat. On my current boat I have a home made boom brake which has a fixed wide large diameter ‘sheave’ between two cheeks (imagine a block where the sheave does not rotate). Friction is adjustable by the number of turns the line takes around the sheave and by tensioning on a cockpit winch adjacent the helm. It’s all aluminium, so it’s light; a bit primitive but so far, so good…
@@captratty2167 That sound pretty good. Walder makes a similar sounding one but charges around 600quid for the privilege (a little rich for our wallet).
How would preventing a gybe be bad for the rig? Sheets hold sails in all sorts of points of sail. Stopping a boom hitting your head is a much better idea.
When I climbed I could happily bound down a cliff on a figure of eight, how on earth is that going to stop a powered up sail?
@@sailingaphrodite4189 The point of a boom brake is only to slow down the gybe, not resist it. Hopefully in time to duck the boom! Surfing downwind across a river bar in a strong wind gets fairly exciting, so the last thing I want is to deal with a broach, backwinded main, loss of steering control - whatever. If the boat needs to gybe, I will let it happen, but hopefully under control. Having said all that, some sailors prefer preventers, and obviously use them successfully; others ditto boom brakes. Like the argument of hanked-on headsails versus roller furlers, we solo sailors all have our preferences, based on experience. What works on a 30ft boat could be quite unsuitable on a 50 ft boat…no argument about that!
You can put a net around the hull to prevent falling into the sea as well.
😄The whole way around!?
@@theincompetentcrew Yes, it is dangerous to fall into the sea just as it is dangerous to be hit on the head by a boom
@@antebratincevic6764 I think most would clip to jackstays/ lines in bad weather? I am trying to imagine a boat wrapped in net. ..
@@theincompetentcrew The same is the case with the tied boom, if it remains windward, stress will occur in the entire rigging with all consequences, including the spreader in to the sea.
I wanted to say that you should walk on the deck without exposing yourself to the path of the boom and mainsail sheet, just like when you walk on the deck when you have to be careful not to step into the sea.
Anyway, I just presented a different approach to understanding sailing, because everything depends on the human mind and various influences on it.
My first sailing was a long time ago in Optimist class and I can't remember if my first maneuver was gybe or tack, but I remember well how I had to keep my head.
@@antebratincevic6764 thanks for sharing, its always good to have another perspective. :) I hope you follow along. Ben
Recover a crew that goes overboard...??????
Why would you do that....?????
A very good set up for a preventor.
Well, if we didn't, it could create a lot of paperwork.
What's new?
I don't see how the boom is being held back tightly enough. Doesn't such a long line led so far forward and back again, with the attendant slack and a bit of stretch, still allow the boom to swing in?
Hi Tony, the point of the demo is more focusing on already having the pre-rigged preventer on the boom so it can be rigged easily underway. There will be stretch, a lot of people will run it back to a winch and crank it tight (which also gives the ability to release and ease when you decide). The reason the forward fairlead is chosen- gives the strongest angle to hold boom out. if the wind does back the sail, it will cause the boat to round up . The boom will come in a bit, obviously depending on how tight the line is. Most would consider this better that the other option- a boom swinging across the deck and snapping itself or damaging the rigging. Thats the idea anyway. Worst case- cracking a head that wasn't expecting it.
@@theincompetentcrew Thanks IC! Still learning...
@@tonybarnes3858 so are we :)
You want some stretch for sure because either the line stretches or all the force goes into your mast via the boom. This is also why it is important to use a line with stretch and make it long enough to allow it to go over center. There is a heated debate among the Amel crowd over this if you want details you can look at that. A boat was dismasted coming down the face of a wave due to a gybe. The debate is over the way the prevention was rigged and how it caused the issue.
Why use three lines when you can do the same with two? One on port the other starboard.
You know when you are about to run downwind. Forgetting to rig a preventer is just 'piss poor planning'.
The change around after a gybe has never bothered us. Its a classic way of doing it. Its not forgetting to do it... It just makes doing it easier and safer, as opposed to tying a line to the end of a boom that’s shaking over the deck (pointed to wind) or out over the side while the boat is heeling. I suppose it is possible to rig them as you leave the marina with two lines. But we are also not a big fan of loose ropes hanging down in the cockpit from the end of the boom, or ducking under lines going forward (presuming it has to go over the guardrail). Its definitely a possible way though to have two pre rigged I guess. I guess each boat is a little different. We are forever going up to change sails. I think the only point it becomes poor planning is the day somebody doesn't do it and has an accidental gybe. Thanks for the comment.
Yet one more line to have to attend to. Just no.
Not for everybody. Thanks for commenting
buy a crash helmet then...
