I love the way this is presented calmly and thoroughly, with all details explained in a simple way. I understood all the aspects of it, which is not always the case when professional sailors try to explain to less experienced ones. Thanks a lot.
Honestly, some of the best Sailing training videos on the internet, I stopped sailing 30 years ago and have forgotten so much, your videos are helping me so much! Thank You!!!! And thank you for not adding stupid music like many people do!
These instructions are excellent (as you would expect from a sailing school) for an armchair sailor learning the theory of sailing, many thanks for your videos.
EXTREMELY thorough, I appreciate all the details and repetition. I fully understand what to do now! We had a close call with out Hunter 25 when our dog roamed into the sheet area when we were having an accidental jibe. I managed to pull our pup into the cabin before it happened but It wasn't very windy.. If it had been higher winds things could have been a lot worse.. - Chad
That's my biggest worry. I'm scared the whole boom will fly off the boat. I don't know though, I still have to go to sailing school with the other sailors to gain confidence. Thanks for the upload. Seems like the way to do it and not get hurt.
This didn't get enough attention during my sailing training. Had I watched this a month ago, I wouldn't have had the boom sheet break my arm during an accidental gybe. That was an effective, though definitely not the best, way to properly learn the risks of gybing, but I very much prefer your way of teaching this! Thank you for a very well presented lesson, I will go out and practice once my arm has healed.
+Maryland Sailing School How do you secure /rig the bowline to the end of the boom? I believe you mentioned that the loop goes thru the clew of the mainsail? That part was not clear to me. Great video and very helpful. Thanks
+Luis Santiago Pass a line through the clew of the mainsail and around the boom, and tie a bowline to form the loop around the boom. The reason that I put the line through the clew, is to keep it in place so it does not move fore and aft along the boom. There may be other ways to accomplish this same end, but I find this to be fairly simple and workable... Tom
+Maryland School of Sailing - That makes sense and it is simple to implement and doesn't required any special gadget. Thanks for the quick reply. -Luis
Another great video. These are especially useful for me as I have an IP350. I wonder if you could compare the use of a boom brake to a gybe preventer. Can a brake serve the same purpose or is a preventer preferred? If a brake has a different use case when is its use appropriate. Thanks again for such clear and instructional videos.
+Tom Moss: A boom brake will, of course, not stop the boom in an accidental gybe, but will only slow it down, so the hazard of hitting an unsuspecting crew member still exists. In strong winds, you need to set the tension of the brake higher to achieve its benefits, so you then increase the chances of boom damage due to a dip in the seawater as discussed in the video since the brake attaches forward on the boom. I'm not inclined to use a boom brake since its extra hardware hanging from the boom, plus the athwart ship lines need to be stepped over when going forward or working at the mast or furling/lashing the mainsail... Tom
Thank you Master! Something I would like to mention is that you are not only an excellent sailor but also a real Instructor with effective knowledge transfer.
Im just a newbie but I’m sure my single line system is simpler and you don’t have to leave the cockpit. The single line has a quick connect clip on each end. The line runs from a ring on the boom end, forward and past the shrouds on one side, through a sheave attached on the foredeck and back via the other side of the boat to a cleat in the cockpit. During a gybe, when the boom is sheeted hard to the centreline i release one end clip and attach the other. The loose end now becomes the cleated end and vice versa.
What is the procedure if sailing single handed? Seem you mut have Port and Star Preventer handed onto the boom. Make the change when the boom is centered.
I have watched hours of sailing instructional videos over the last several days as I am contemplating the purchase of a boat. I have a friend who owns one and is willing to teach me how to sail a boat before I make my final decision as to whether or not to purchase one. I must say that of the many videos that I have watched, this one is the most organized and informative of them all. Thank you so much for your willingness to make and post your videos. I have subscribed to your channel and plan to watch the rest of them.
Just do it. I'm considering the same, I'm currently sailing on a 60' retired ocean racer, after not having sailed for 27 years. It is not all that complicated, until the weather gets grim, you should get out and sail as much as possible, and do a competent crew course, and get on boats for passages, day sailing and passage making are two very different worlds
I bought a 22ft sailboat and with absolutely no knowledge sailed from Poole Harbour South Coast England to southampton through hurst castle against the tide 12 hours sailing and experienced multiple crash gybes untill the runner broke from 1 end did not know what the hell was going on how I managed to get main sail down i just don't know I've researched and researched why and how to deal with it THIS VIDEO IS THE ONLY 1 OUT OF COUNTLESS THAT EXPLAINS PERFECTLY WHY AND HOW TO DEAL WITH AND PREVENT You are an amazing teacher I have subscribed
Outstanding video. It really helped me understand rigging a preventer on my boat and gives me a firm understanding. Now I know why those forward turning blocks are there. As a side note when I disassembled the boom on our 30 year old boat to get the caps powder coated I discovered the forward aluminum cap was split internally at the goose neck, damage resulting from an accidental gybe sometime in the past. Had to replace the cap.
Always informative and well done videos from Maryland School of Sailing and Seamanship. Best explanation and videos I’ve seen on the use and handling of Preventers.
It took me time to understand that the "sheet" is not a plane, but a line. "We have a nice system..." at 25:30 - but on the opposite side of the mast, the "system" was anything but nice! Wouldn't a boom brake prevent all that? Thank you for a nice presentation!
There are no "ropes" on a boat because all the ropes have individual names according to what they do. A "sheet" is a rope/ line that attaches to the "clew" (corner) of a sail in order to control the sail. A boom break might prevent some of "all that" but boom breaks also have their advantages and disadvantages, and require skills for operation.
@@SerbanOprescu He was addressing your confusion about what a sheet is, which is usually taught well before you learn the intricacies of jibing. I too was confused by your terms, like what is a plane (outside geometry)?
@@markisfeld4046 My wording was indeed referring to geometry. Geometry does include lines and planes (as it appears you already know), and in lack of additional data I associated „sheet” (like the bed lining) with a plane. Hence when hearing the word in Roger's video, I was confused. This being said, Roger's remark about 'not called ropes" had no object, since I never used the word. Thank you for your post.
Congratulations on a well thought out and information presentation. This is a topic that has always confused me ........ no longer. Would love to see a similar presentation on sail trim.
Excellent video, this is a really simple and highly effective and stable technique, two questions, firstly, could you not just use frictional resistance on your preventer when easing and just winch in on the sheet? And the second question relates to adjustments to the vang during and after gybing?
Very interesting. Would it be better to use two lines in rough conditions so you don't have to go forward to relead it? Also when you made the bowline around the boom, is it just loose around the boom or through the clew eye?
I can obviously see the point of rigging a preventer but my question is - by moving the traveller and boom to the centre line in readiness for the gybe, are you then not massively overpowering the sail (effectively close-hauled in a reach) for the time it takes to move the preventer to the other side of the boat? Thanks if anyone can answer.
You are in no way "overpowering" the sail. The effective area of the sail that the wind can "see" is reduced and so is the wind power. Cranking in the main before the gybe is normal procedure, regardless of the preventer. When sailing close hauled, the sails function like airplane wings. When you are reaching or running, the sail functions more like a passive resistance to the wind. That makes the difference
If you are "overpowered" on the Main for the conditions, you could round up when you sheet in. This is common in boats that are sailed for performance. If you are sailing the boat this way it will be nessisarry to trim the main in and ease smoothly as the gybe is happening to prevent an uncontroled main sail and overloading the rudder. Hopefully this answers your question.
Thank you very much for the comprehensive video, Capitan! What would also be interesting to examine are the methods of safe jibing under gennaker, avoiding broaching etc. Thanks again
Is there concern for damage to the boom by holding the preventer at the end of the boom and the sheet further forward? I know a boom is tough but it seems to be an unusual stress.
Sorry. Certainly not forward of the sheet. Maybe at the sheet to boom connection? Since you did not see a problem then perhaps there is none. I don't have a second nature understanding of the forces on the boom and mast. I know they are considerable and have always been cautious with heavy strains on equipment. Farm machinery and rigging of that sort. You can get dead quick with thousands of pounds on a line or chain.
+Pass Me By Yes, the sheet to boom connection is important as are all rigging connections, and they all require regular inspection and maintenance. But, assuming that the connections are maintained, I worry more about mast and standing rigging failures than about a boom failure. The video simply makes a point about damage inflicted on the boom by malpractice in the two situations mentioned: One a severe accidental gybe, and secondly using the vang as a preventer. Thanks for your comments... Tom
Thank you from a guy who has always been on power boats. You explanation was complete and logical to the point a guy with no sail experience could totally comprehend your instruction. I plan to build a Wharram Cat for my next boat. so I do appreciate your class. Thank you again.
I'm in hotel quarantine and I felt like I was out there sailing with you. Thanks for the day out and lessons learnt today on safe gybe manoeuvres. Happy sailing! 👍
With a tight mainsheet, centered traveller, and wind directly aft - I can't see what the risk is, nor the need for all this added complexity.. What am I missing? As the apparent wind swaps over during the turn, the sail harmlessly and silently gybes. The danger is only if the helmsman makes too greater turn, or the sheet is released and overpowers the main when the crew aren't ready for it, resulting in a very large heel or worse, a dramatic turn windward.
Great video Capt. Tursi. As a ASA 118 graduate of MSA, Sep 2017, I know the quality of your school's education. I sail an IP31, my question is; How long should my preventer line be? I figured (31/2) for midship + 14 for boom, add 5, make it round figure 35 feet for my IP31. Am I off base? Regards, Ziya Gun
ty for a great video ! i was going to use a tackle to the toe rail, but like your method better. do you think it possible to eliminate the vang with this system ?
Thanks for a great video. We are confused about how to attach to the boom: the following link moves video to 2 minutes 47 seconds: ua-cam.com/video/qAhUWCa-KoQ/v-deo.htmlm47s At this point the instruction is to 1) Tie a bowline around the boom. 2) Run the loop of that bowline through the clew of the main sail. But from the actual video it looks like the loop of the bowline hangs loosely just around the boom and nothing is going through the clew of the main sail. The following link moves video to 6 minutes 41 seconds: ua-cam.com/video/qAhUWCa-KoQ/v-deo.htmlm41s At this point the instructor shows tying bowline knot to boom, but there is no evidence of anything going through the clew of the main sail. And the loop of the knot just hangs loosely. Can you further explain what needs to be done with the bowline knot? Thanks!
Thanks so much for responding. So in terms of the tree-rabbit bowline analogy, are you saying that the line goes around the boom and through the clew of the mainsail prior to going up the rabbit hole?
One more question: this is a dumb question but just want to verify: when we are reefed, the line would go through the reefing clew not the regular clew? So there would be two lines going through the reefing clew: the reefing line and the preventer line?
Hi Ty formte great video - little remark: I’d go closer to the wind before initiating the gibe (I.e. crankin in the main sheet), prepare the preventer as shown here and then only I would steer into the gibe.
A little closer to the wind? Take another look at the wind direction in the video. If you are in any decent wind, it might make more sense to have the main reefed down more, depending on the size of the main.
Your desired destination may not be straight downwind, it may be in another direction requiring that you reach off. Also, in light winds sailing straight downwind may be very slow, and reaching off for a "downwind tack" may be more desirable, and in this case the gybe will be repetitively used... MDS
Excellent. Very glad to see you teaching the use of a preventer and an excellent method of safe gybing. Still not happy about your locking turns though. With your method of tying off to a cleat, I have seen a line under tension (for example the preventer holing the boom after an accidental gybe) start to run as the locking turn is released which caused the locking turn to lock again. I worry about fingers getting caught in the locking turn as the crew member attempts to hold it.
I suggest not releasing the preventer under tension after an accidental gybe. Rather, crank the mainsheet tight to take the load, then release the preventer. This way you always have positive control of the boom... T
As a U of Maryland grad, I'm interested in anything Maryland as I'm in Michigan! Appreciate the video--gotta admit, I've never rigged a preventer but you've simplified it such that it'll be a no brainer for me and my crew. Wondered though, a lot of discussion about attaching the line thru the clew and around the boom. I'm wondering, if I can attach the line to one of the fixed loops on the bottom of my boom closer to the center of the boom. Would that cause problems in terms of torsion on the boom, risking bending or breaking the boom? Or, would it improve those conditions such that it would be less of a risk?
Ok, now that I watched the rest of the video, I know that it's important to attach to the END of the boom in case of heeling to the point that the boom end is in the water on a serious heel. The support by the preventer and the main sheet will provide support such that it doesn't bend the boom.

Mitch G excellent and very informative demonstration, the most detailed i've seen fpr a newbe like me.
This is great, but sounds like a chicken gybe would be less complex and faster 😂
Is a chicken gybe just tacking?
@@chrishnah yes.
a chicken gybe addresses intentional gybes but not accidental gybes.

Finally! A great video that clearly displays all aspects of rigging a preventer!
in strong winds this safety measure is very useful. Safe for crew and boats rigging.
Hi ! Thank you for those very clear explanations
Well explained, ive always heard of a preventer and found little info on how to rig one. At least now I know what the preventer tool I have is now!

Thank you very much for your explanation and showing examples of the use of a jibe preventor.
Why gybe at all rather than just run down wind with the sails full out?
Your desired destination may not be straight downwind, it may be in another direction requiring that you reach off. Also, in light winds sailing straight downwind may be very slow, and reaching off for a "downwind tack" may be more desirable, and in this case the gybe will be repetitively used... MDS

That’s a stupid question.
Thanks for the video! Really cool boat, too! I've been sailing only smaller boats but look forward to having that setup in the future :)
Captain! Thank You !
Excellent. Very glad to see you teaching the use of a preventer and an excellent method of safe gybing. Still not happy about your locking turns though. With your method of tying off to a cleat, I have seen a line under tension (for example the preventer holing the boom after an accidental gybe) start to run as the locking turn is released which caused the locking turn to lock again. I worry about fingers getting caught in the locking turn as the crew member attempts to hold it.
I suggest not releasing the preventer under tension after an accidental gybe. Rather, crank the mainsheet tight to take the load, then release the preventer. This way you always have positive control of the boom... T
Top drawer instruction. Happy sailing all
Thank you for sharing your expertise and knowledge
Love these videos, thanks so much!
Top notch instruction! Thank you.
fantastic video with a lot of good info!
Another very informative video!
Thanks, great and organized video. Worth to spend some time in that

So well explained. Thank you.
Captain I loved the lesson, now I know! Thank you!
As a U of Maryland grad, I'm interested in anything Maryland as I'm in Michigan! Appreciate the video--gotta admit, I've never rigged a preventer but you've simplified it such that it'll be a no brainer for me and my crew.
Wondered though, a lot of discussion about attaching the line thru the clew and around the boom. I'm wondering, if I can attach the line to one of the fixed loops on the bottom of my boom closer to the center of the boom. Would that cause problems in terms of torsion on the boom, risking bending or breaking the boom? Or, would it improve those conditions such that it would be less of a risk?
Ok, now that I watched the rest of the video, I know that it's important to attach to the END of the boom in case of heeling to the point that the boom end is in the water on a serious heel. The support by the preventer and the main sheet will provide support such that it doesn't bend the boom.
Yes, end of the boom is preferred for the reasons that you state... T
Thanks very good very detailed
would it be better to put the preventer closer to the mask?
