With 40 years sailing experience, I can say this is hands down about the best explanation about heel and counter acting forces I've ever seen. I'm gonna use this in training.
@@SuperDirk1965 it's not just the surface that counteracts leeway. The lift produced by the keel, rudder and hull are very much a product of shape, and modern shapes are much more efficient at doing that with less surface, so less drag. The righting moment produced by the keel and the hull is a product of the centre of buoyance moving to leeward and the keel providing a low centre of gravity. The lever arm between these is counteracting the heeling force of the rig. Which would mean that wide boats are faster because the centre of buoyancy moves further to leeward, but the drag increases at about the same rate....
Well-explained concepts. Bravo. So if I understand correctly, the heavier and deeper the keel, the more sail I can have, the faster I am? There are no limits? On a 12 meter can I have a 100 sqm mainsail and an 80 sqm Genoa?
Generally you adjust the sail area to get optimum power & heel. You do this by making the sails smaller when the wind is stronger by reefing the sails or using smaller sails. You can also use the control lines to make the sails flatter, which gives less power.
That's beginner's misconception. If you experiment you'll find the boat will be faster with less heal, so reef early with no loss of speed and ease the traveler to avoid being over-powered and you'll sail faster!
the amount you have to have the rudder off centre to go straight is called "weather helm". Most boats go upwind best at around 5⁰-7⁰ of weather helm. Offwind there should be no weather helm
In my opinion, the best moment to reef down is when you first begin to think about reefing. Half an hour later, your crew will say, we're glad that we have reefed already...
Molto bene! Grazie! I have only been at the helm for 3 or 4 years and learning the hard way. But this video has stitched together so many of the points that I believe I have learned that I now have what I feel as a cohesive understanding of this aspect of sailing. Now I need to go out and practice! Ciao Bella!
Your video should be on two parts . For people who understand physics and for those that just need to know what has to be done. Boat is learning when is upwind. To correct, you can do one of the two things, depower the main, or turn the boat more up to wind. When we have strong wind, I always keep the main sheet in my hand.
This was very informative and answered many questions. I preferred trimarans because of the almas on each side for stability, but I see it’s a matter of how much sail is out and needing to reef in the sail.
Great Video!! I am just getting into sailing this year and found this very helpful! Can you explain what the small outboard engine is used for? I have seen this on a few occasions now, but do not understand why such a big boat would have such a small engine, especially since I imagine they have a larger inboard engine.
Once in the bay, you will need to go ashore. To do this you have a small dinghy tender and this dinghy tender needs an outboard motor unless you want to paddle to shore. This is why you will see the outboard motor on many boats. Some keep it in the locker, others have it attached to the stern.
Heeling is how fast winds your boat can take for the tack. Some boats can only take 20 knots winds before they start heeling, others can take faster winds and go faster without heeling. On a cruiser sailboat you should REEF the mainsail before start heeling, when you reef you can take stronger winds without heeling. Each boat has a "speed limit" vs wind speed, you control the speed of your boat by reefing, you dont wanna heel on a cruiser, so you reef you mainsail if the wind gets too strong for your boat.. less mainsail less wind force on the boat whilst keeping the speed limit of your boat without the need of heeling.
The boat is a Scuderia 50 designed by Umberto Felci. Felci is known as the designer of the Dufour. The boat was built in small numbers at the beginning of the new millennium. It won many races in Italy and is still a very interesting boat, even if its lines are too old to win important regattas.
We didn't mean to say that 25° heel is not much. We ment that, even when the boat appears to be extremely heeled, so that you might feel it is 40°-45° with the toe rail is in the water, it is actually heeling by only 20°-25°.
As you will have seen in all the videos of sailing in the Mediterranean, unless the wind is very strong and the sea very rough, people do not wear life jackets as they do in the northern seas. They are not all unskilled and are no worse sailors than those in the north, it is just that the weather conditions are different in the Mediterranean. The wind is seldom very strong and the sea very rough, while it is often very hot, and when it is very hot, wearing a jacket, if it is not indispensable, is not recommended because it significantly increases the body temperature and prevents good breathing; several foreigners who come to Italy and want to follow their navigation manuals to the letter and wear a jacket, then feel ill and sometimes faint, greatly increasing a dangerous situation that would not otherwise exist. This is confirmed by the fact that foreigners who come to Italy to go boating, when they leave the port for the first time, all wear life jackets and when they return at the end of the week, none of them do.
On the yacht only high class specialists, and they show how not to take care of safety. Congratulations and I hope that no young sailors are watching you. You are doing a bad job...
We are sorry, but we have problem to understand what you mean. Specially if there is something that you do not like, may be it is better to be clear. Thank you
I finally get things I never got before!
Maurizio, you're freaking awesome at explaining stuff.
That was crystal clear, my friend!
This is so damn interesting!
Longtime sailor of 63 years. Outstanding video.
With 40 years sailing experience, I can say this is hands down about the best explanation about heel and counter acting forces I've ever seen. I'm gonna use this in training.
Hey, dude, you're freaking awesome!
So, it's not just about the weight of the keel, but also its surface, right?
No. It's just the force from the sails v the weight of the keel.
The surface counteracts the sideways movement of the boat. The depth of the keel together with the weight is what keeps the boat upright.
@@SuperDirk1965 it's not just the surface that counteracts leeway. The lift produced by the keel, rudder and hull are very much a product of shape, and modern shapes are much more efficient at doing that with less surface, so less drag.

@@deerfootnz This is about the heeling of the boat, not leeway.

Why would you? The speed of the boat is limited by it's waterline length.
Now I get why my boat's rudder became so hard to move.
I thought having the gunwale in the water was the real sailor's way to sail.
That's beginner's misconception. If you experiment you'll find the boat will be faster with less heal, so reef early with no loss of speed and ease the traveler to avoid being over-powered and you'll sail faster!
When was the last time you greased it?

Sardinia it is the best place in Mediteraneen sea
In June I will go to Cala dei Sardi, I hope to meet you there.
Thank you

We agree with you 100%.
Totally correct! Here we use to say: if you think about reefing it's too late.
Very good video, my friend
I checked out your digital magazine. Don't you have an English or French version, by any chance?
Really great explanation - graci

Thank you for showing and explaining this practically.
Thanks! A fine and practical explanation of the basics on sailing.
Is it possible to make a video in the use of the traveler.
The idea is good, we will try to make it happen.
This was very informative and answered many questions.
I preferred trimarans because of the almas on each side for stability, but I see it’s a matter of how much sail is out and needing to reef in the sail.
well done Sir , thank you very much
It seems that the wider stern design gives the boat more heel and still maintain speed v weather helm.
Great Video!! I am just getting into sailing this year and found this very helpful!

If I pay, can I come along and do these things with you?

I also watched the other English video. Sorry, I don't speak Italian.
Excellent advice
Damn pops, you’re savage. 😂
When the boat heels I get scared
Could you please introduce us to the boat, what boat make was that etc. Thanks?

nice information a tad on the vague side but worth a viewing .
Bravo!
Too many, especially here some sharing there experience on youtube, forget to act first before it's absolutely needed.
Curious.
20 - 25 degrees of heel is very little? I am obviously not a racer. That's a lot to me.
We didn't mean to say that 25° heel is not much. We ment that, even when the boat appears to be extremely heeled, so that you might feel it is 40°-45° with the toe rail is in the water, it is actually heeling by only 20°-25°.
Most racers will sail with much less heel than this. 10⁰-15⁰ would be the most heel, or something like that.
Clear as mud
When thinking about reefing it´s time to reef.
Exactly
If you are that good ,why are you not wearing life jackets ?
As you will have seen in all the videos of sailing in the Mediterranean, unless the wind is very strong and the sea very rough, people do not wear life jackets as they do in the northern seas.

@@solovelanetno! You have to wear jacket , but I don’t too. That’s wrong.
"When the boat heels", sounds like a soap-opera..., anyway.....
How about you show people how to wear PFDs by setting an example?
