I find the presentation style perfectly fine. Sail trim is a convoluted subject that's super difficult to explain well, but I've learned a lot from this talk. My only regret was that the rig model behind Ian isn't used at all. I reckon it might have been pretty helpful as an aid.
Ian. Thank you. I watched this and changed the way I trimmed by J24...that year I came tenth in our Australian Nationals and won a race. Thank you!
I loved the content and the style, it really works for me
Well I enjoyed it!! Thanks Ian. I'll send it to the crew as homework, but of course what we really need is more practice and a good trimmer on board for a while!!
Still enjoying this video years later!
2021 - and with the Lockdown I am Upsizing my Knowledge on Trim : Thanks Ian ! for a Very Enjoyable , Candid and Sympathetic Presentation of a Complex Subject that you have Managed in a Simple and clear Manner - The Stuff of Legends in my Books //I will Use this as my base reference In my Journey towards Sailing my Own Yacht ...
Best Regards Jerry [Australia]
Fantastic thanks. I always feel like I know nothing when I take the time to learn how to sail properly.
Good explanation, thanks.
Great content. Thanks a lot
Thank you. Excellent information.
Really informative! I loved being able to visualize everything!
Not gonna lie, though, I laughed my butt off when he said mainshit! 😂
“Harden the mainshit!”
“But Captain, I already did just 30 minutes ago”
nice video demistified some for me , thank you
The front of the jib and the back of the main. North U in the eighties. Good times.
Arriva arriva arriva.

Reaching = Mainsail outhaul eased?
At the start of the video you mentioned how in light airs you want "deeper, fatter sails" to make power. However I have always been told to make the sail as flat as possible with an open leech in light airs so the wind finds it easier to pass over the sail and does not stall could someone please explain the idea behind the ideas please.(Is it just because yachts are very different from dingys)
Joshua Kendle, Lift is created by the acceleration of air over a curved surface, this causes a decrease in pressure and therefore “lift”. The lift can be varied by altering a few variables; 1) The curve of the surface 2) The speed of the airflow (wind) 3) The surface area of the curve.
So keeping that in mind in light air, option number ‘2’ is a constant, dependant on wind strength, and option 3 if you have a full sail plan is also constant so we can only alter the curve (like flaps on an aeroplane).
If the wind is light, a deeper curved lifting surface is required (deeper sails / loosened outhaul) to attain the most lift possible by creating the largest curve in the sail for lift for a constant wind speed and sail size. The limiting factor is preventing the slower airflow from stalling before it reaches the trailing edge of the sail if the curve gets too deep or the wind gets too light
Thanks a lot for replying. So depth and therefore curve is a balancing act between overdoing it (and the air stalling) and having enough lift in lith airs? Thanks again
I know this comment is 2 years old. But what you wrote Joshua applies to very light air, where a flatter sail shape is required so the flow remains attached
would help the presenter didn't stand in front of the slides and if the slides could be seen. also explain some the terms..many were mentioned but not defined..maybe its because I'm learning and don't know all the terms..
Can anyone put the subtitles in spanish? I'm from there and it's a bit difficult to understand all what he is saying... There is a lot of sailing content in English but not in spanish :(
Try your best
You can autogenerate subtitles in TH-cam.
Excellent explanation....don't be turned off by his style and accent..quiet and a bit of a mono tone but not a word extra or out of place. Stop and go back until you understand it....no for all but for racers a must. excellent lecture...I re-watch it
wrong when you are going downwind the round sail shape is worth more than projected areaso many wrong expertsgo sail a dinghy and learn it properly
+Joe Nemesis
Why don't you learn how to use periods to make complete sentences? Reading your comment is a chore.
depends on the situation mate ,there are so many variables , are you on a dead run ? by the lee? flying a spinnaker or not? going for speed or depth? your not wrong and neither is he
Go to English class and learn some spelling and punctuation and then come back, perhaps we'll take you seriously then. I expect this guy has done more dinghy sailing than you've had wanks. He's a fucking sailmaker you twat...who are you?

Joe English please
Frankly a poor style of presentation. I suspect the speaker has a wealth of knowledge that would best be imparted by sailing with him. But not in the classroom!
For really effective presentations on sail trim, one simply cannot do better than the video clips of 'PP Consultant'. Try them . . . brilliant.
PEEPEE WHAT?
man i wanted to watch but he is so dull i fell asleep
learning can look dull
If you wanted to put people off sailing for life, encourage them to watch this video; apart from the fact that the narrator has had a charisma bypass and could bore for Britain, much of what he says is - if not incorrect - then at the very least, debatable.
Hi David, I'm sorry you didn't like my talk but there's absolutely no need to get personal about it. Whilst I concede that I 'don't know everything', there are many aspects of our sport that will always remain open to discussion or interpretation. People sail boats in different ways and although there are many general guidelines that will benefit most people, the fact is that what works for 'one' doesn't necessarily work for 'all'. For your information I have raced sailboats at a decent level for over 40 years during which time I have won 10 National titles, 2 Europeans and placed top 5 in several World's. I say that not to brag but merely to illustrate the fact that I feel that I am reasonably qualified to talk about sails. We're all entitled to opinions however and if you don't like mine that's fine, tell me specifically what you disagree with and I'll be happy to answer with an explanation. If I've got something clearly wrong then I'll be happy to learn from your expertise but please keep your personal views to yourself.
Ian's presentation may not suit the best learning style of every viewer, and maybe it does take a bit of discipline to get through it, but it's completely worth the effort to do so. With one possible exception everything he said conforms with current theories and sounded reasonable. The only question I had was the few words about clogging the slot. I won't say a guy with his record is wrong, just that there are differing opinions on just how important the slot is and how it can be best set up. Overall this is a great video. Watch it and even take notes!
David Leigh - I my immediate reaction to your insulting comments is to replicate your behaviour BUT that would be lowering myself to your level.
Half way through and I’m going for my pen and notebook to try and maximize my learning. Seems like a genuine and learned sailor to me and his calm understated delivery is much preferred -imo- to some loud mouth whose opinion of himself exceeds his capabilities - just saying is all David - must emphasize there is no reference to you, unintended or otherwise, in my comment
Just to add one more thing: the video's title has the word 'masterclass' in it, it's not meant for beginners. Someone who doesn't need to be persuaded to go sailing and who has a solid understanding of sail trim already should thoroughly enjoy the video, I think.
Thank you Ian, I learned a lot from this!
David Leigh. A nasty comment which serves no purpose.
Oh for goodness sake. This is why sailing boat design has resulted in the most UNCOMFORTABLE dinghies and ugly yachts in history. The racing and trimming fraternity now dictates EVERYTHING about dinghy and yacht design. By all means have a race or trim obsession if that turns you on, but this obsession is a substitute for and ignorance of the aesthetic pleasure of sailing, and unfortunately has now become a collective obsessive compulsive disorder.
This is by no means a personal attack on the chap here. He is just one of hundreds who really think that being afloat is just about getting the tiniest fraction of a knot using very debatable theories. WHO CARES!
Bias much? If you don't want to sail efficiently the don't watch videos about trim! I've sailed many older designs that are considered "classics" but they have been complete DOGS. Most of the yachts I have sailed that have been an absolute pleasure to sail in all conditions are later designs. That goes for dinghies as well, give me a modern Aussie skiff over some of these "classics" that are still sailed any day. Horses for courses, any blanket statement about design is mostly rubbish. You can find good and bad examples of them all with no single feature being determinant of general characteristics and performance. Every design needs to be evaluated on its merit and its ability to meet its intended purpose.
@@zedthehun Point taken, but after many years sailing in Cornwall and living there, time and time again I see trim obsessives gaining less than half a knot (usually a quarter) or over-canvassed for the sake of barely half a knot. If you are into racing fair enough, but not everyone wants to race. Some find it incredibly boring. As to design, if I want to go to Fowey and back for the day, I couldn't care less whether I take half an hour longer than someone else. I get to see lovely scenery for longer!
@@fingerhorn4 I sail in a club with plenty of people with that attitude and the fact is when it comes down to it they can't sail very well because they cannot tune the rig, they don't get the dynamics of the rig. Oh and 0.5 a knot is huge when your top speed is 6-8 knots to windward. However, it is more about balance, handling, heel angle etc. A well sailed boat is comfortable, speed is a byproduct. If they are on their ear they are going slow. Typically flat is fast and sail/rig tune can keep you flat without pulling canvas all the time.
So much good information but such a bad presentation. So sad.
This presenter is such a snoozer...zzzzzzzzz
