Heyyo! Love the vid, just wanted to share that the "equal transit theory" is incorrect, as the molecules don't have awareness of one another to both reach the trailing edge at the same time. There are high and low-pressure vectors on the wing/sail, and Breunoulis' Principle is true, just not the equal air molecule idea.

It's best to remember that sails work in a compressible fluid (air) and the hull is in an incompressible fluid. I don't agree with her description of Bernoulli's principle applying to the water flow around the hull as the primary force causing windward or leeward rotation. When speed is low, there is too small of an effect in the water- but that is not true of the wind that is flowing over the sails- at hull v=0, air v=max. The change in waterline length and exposure area of the hull vertically against the water are more significant. This would be better explained if the video included a discussion of center of pressure and the shifting location of the effective center of pressure. When the center of crew mass shifts aft (the rear of the boat), the geometry of the hull forces the center of pressure of the water around the boat to shift aft, and vice versa when the center of crew mass shifts forward towards the bow. Under a constant wind flow and sails slack, the wind drag can be assumed to be fairly evenly distributed across the exposure of the sails, masts, and above waterline hull, and the boat can be rotated and pointed either upwind or downwind to a small degree due to the offset, the eccentricity, between the center of air pressure and the effective center of pressure of the hull against the water, that is the resisting force.

I’m from the Georgia Tech Sailing Club. This video really helps in my learning

Great video! Would be great if you can make one on how to predict a lift/ header before it hits

At age 18 I asked the man winning 16 foot jib and main sidewinder class race "How do you decide when to tack"? His answer was your definition of lift and header. I started tacking on header and finished first 30% and second 70% of races out of 12 boats. We also ran Olympic course Wednesday nights.

Best explanation I’ve heard

Great explanation.

In a race always point up to the lift, correct?

very helpful, hope i win my next race with this tips!

Excellent video

Skippering my first high school race this gave me some more confidence

excellent

This is cool. I knew all this stuff, I just wanted to see and hear you!!!

Yes, very well narrated, succinct, no jargon. Nice.

Sounds like a very manly female

Great FJ tips. Sailed a Laser for 20 years but have been sailing my dads 1967 FJ the last few years in our club races and feel like I’ve forgotten how to sail 😂. Will put these tips into practice next season 👍.

Great video. I like her sense of humor.

Great vids, thanks- and they’re over six years old now so hopefully you’ve passed your exams… BTW your map was upside down. 😊

Valuable. Really helpful and very practical. A technique that builds confidence. Tougher with unirig but also works.

Excellent teaching video. One to save!

for all the Rudderless sailing how to videos... this is the only one that actually EXPLAINS its, not just shows it

I wish you had more videos! These are great! I am new to racing this year and have been learning from my husband...but I would like to hear about this stuff from someone else, said in a different way as it is not coming easy to me!

This girl's a trip. Makes learning fun

Regarding your description of weight placement…every boat I’ve ever owned has responded exactly opposite. I sail a “Duck Punt” and it has no rudder. In order to tack you must move your weight forward. I lived on a Flicka that sailed to weather in light air perfectly balanced. I would lean forward slightly to head up, back to fall off. My current Montgomery 15…same thing. In order to come about I shift my weight a bit forward for a smooth tack. I don’t know where your information comes from, but it’s not supported by my real world experience in a variety of different boats. 🤷‍♂️

It's so refreshing to see a young woman make a sailing video. Good diagrams on the white board, new mannerisms, different choice of words, new way to explain what I've heard many times before, and most importantly, the "feminine touch" which puts a big smile on my face. Keep up the good work!

I watched this video last week. Next racing day, I noticed the line was at least slightly pin end biased so I decided to start down the line. I ended up port taking the start and the line bias turned out bigger than I expected. I lead the next closest boat by 5 - 10 boat lengths. Thanks Allison. I owe it all to you.

The juice part😂

Thank you for a very informative video. It helped me get into ruderless sailing quick and easily! However, there's an error in the information provided. At around 5 minute mark, you stated that moving your weight aft will cause the boat to head up, and moving your weight forward will cause it to bear off. This is incorrect. It should be the opposite: weight aft = bear off, and weight forward = head up. This is due to the Center of Lateral Resistance (CLR) being moved in relation to the Center of Effort(CE): CLR ahead of CE = weather helm, CLR behind CE = lee helm. (Please note that this effect is subtle on a small dinghy with a planning hull). A more detailed explanation is available in the PDF document "Rudderless Sailing" by Joel Brand.

What about spins?!!

Strategies were clearly explained. THANK YOU.

Question from a novice. At 1:02-1:03, narrator says the tack of the jibsail is "the frontmost corner" of the sail. Isn't the frontmost corner of the sail the clew? Should she have said the "tack?" Trying to avoid confusion. Thanks for an overall helpful vid.

New to catamaran racing and sailing overall. Our first and only boat is a Hobie 20 and currently up at nationals in Oklahoma City getting our butts kicked by some very good sailors! Your video helped me to start understanding the wind better. Thank you

One minor correction at around 1:25 - from the prep flag going up to it coming down is 3 minutes, not 2 minutes. Sharing this with some new racers...

I think this video is good practical training because it shows a bit of the chaos of how flags actually are sequenced from an RC boat. Other vids show these perfect simulations where in real life you are trying to make out the flags blowing in the wind and with a confusing background behind them, making them hard to see. They don't always fly straight out conveniently for you to see them. Your boat is bouncing/spinning around as the RC boat bounces around.

What about black flag?

Nice sail girls

This is super informative

Re 2:55 "one of the big reasons why you would switch from wing-on-wing to both sails on same side is if you were going to sail down in puffs and sail up in lulls." Are you able to provide a bit more info on this. It seems when both sails are on same side, we have flow over both sides of sail (so sails are acting like and airfoil), whereas when sails are on opposite sides there is no flow on leeward side and the wind is simply pushing the sails/boat. The following diagram en.wikipedia.org/wiki/Polar_diagram_%28sailing%29#/media/File:Downwind_polar_diagram_to_determine_velocity_made_good_at_various_wind_speeds.jpg seems to suggest that at low wind speeds I would sail on a reach (both sails on same side) regardless of whether I was in a puff or lull, whereas at strong wind speeds I should sail wing on wing. So it seems not so much whether i'm in a puff/lull but what the wind speed actually is. Thoughts?

thanks

What are the two big screw holes at the side

Those lines got unperpendicular real quick.

Best explanation I’ve seen!!

👌👍👍👍👍🏅🏅🏅🏆👏👏👏

Hello from Michigan! I bought a Snipe last year and am sailing and skippering in my very first Snipe Regatta next weekend. I sail some open-class races for fun, too! I have watched your videos over and over again, and they are so helpful! They help me the most to teach my wife (crew) how to enjoy sailing and keep it simple. Having fun is more important than learning the vocabulary. Thank you!

Really fantastic teaching! Easy to pay attention

Me and my dad are getting a 420 and this is a useful guide. Thanks!

Attaching the jib is so much harder than it looks, the hardest part is literally the pin and key chain ring.

great video. Thanks for sharing

Just found your videos! Immensely helpful. I like that you use just the right amount of words and diagrams, they are very to the point and not verbose. Keep doing them, they are the best! Regards Murray and Jean

quick question when approximately would be a good time to start the port tacking teqnique like around 20-30 secs?
