This is not beginning dinghy sailing instruction, it is obviously geared for people who sail larger boats, who are interested in becoming more proficient at finer sail handling techniques. Perhaps you look up these basic sail control terms and then re watch. There is a assumed skill level of people who sail on bigger boats (what these videos are clearly pointed toward) already know the five basic controls on a sail.

Yup. Hard to kill.

You think the laws of physics have changed since the floppy scene?

Ray Harkins one heck of a journey But the shortest way would be down the carabean and though the Panama Canal, but that's the easy part, Now you've got to sail half way across the Pacific Ocean which is the biggest ocean in the world and the last place you would ever want to get lost probably a month and a half to 2 month journey

Ray Harkins 3-5 weeks

PIRATES? Just saying

Based on the comments, apparently this guy didn't explain the physics of the sail very well. I'd maybe take it with a grain of salt.

Agreed. When you can't clearly detect the subtle (at least when on video) changes ostensibly taking place it detracts significantly from the point of having a visual portion to begin with. Put another way, when we can't "see" what you're talking about, it might as well just be an audio file, cassette tape, etc.

Vanes Cunningham etc.... Every boat with a sail can be adjusted this same way.... A vang can be rigged on any boat that has a boom its just rigging..... And there are many ways to accomplish the same effect........ A Cunningham's effects can be done with uphaul... But then you must adjust other things... The Cunningham near helps isolate adjustments... It's all in the rigging... If you're boat don't have it you can rig it with lines... A sail has 3 corners and 3 connections at those corners... And ways to tension the luff the leech and the foot... Those three change the shape.... You can in a fractional rig put a bow in the mast affecting sail shape..... Mast rotation controls can affect the sails shape.... Boom travelers for your sheet affect sail shape..... It's all in the rigging You just think the sail has 3 corners you can pull on... You can pull on some in many directions some things allow you to pull along the sides between the 3 corners... Like semen you bend the Mast you pull forward on the sail between the head and tack.. This pulls along the entire luff but but equally due to the fractional setup and Mast design.... So the whole point is if you have triangle sails you can pull on them in many directions to change shape and if you don't have certain things on your boat to do this pulling you can rig it..... Often times with to many available adjustments it is easy for the sailor to kill the sails shape killing speed or power...... While I'm watching this video I see a sail that has a huge drastic exaggerated deep V shape running up from the middle of the foot to the head..... It's hard to tell shape from video but that V has flats fore and aft..... IMHO flats in a sail are inefficient as hell... Now he has the best boat speed of the day which says he is doing something right but I'm certain from that shape the flow over those sails could be improved considerably from what I see in the video.... This aversion to flats comes from my aircraft design experience.... That said though even flat door shaped Wings make lift

@@jolllyroger1 Thank you chief, I wondered about that sail shape myself. Lots of interesting info about adding lines/attachments to change sail shape in your post. I'm thinking of buy a yacht that doesn't have a traveller (very curved roof above companionway) but I'm gunna find a way to add one, or rig something so's I can keep that boom down when running downwind...I reckon it's good to add bits and pieces to fine tune our yachts...Cheerio!

I don't even sail, but I understood it... Maybe you're just not that smart?

+Liofa whatever, but I'm not the only person that wasted time on this.

You should create a video explaining this, especially the part about how air in wind is not moving.

That's how it was taught in physics lectures on laminar flow, though not meet but join.

Max Stevens , hi Max, if you want to go faster,yes do what he says.But if you just want to sail do what you want. When the sails start to luff bring thin in until they stop, or let then out until they stop luffing. Hope this helps.
