Another 'goodonya' for Alex.
Wonderful contribution.
Thanks.

Awesome job Giu!!!!

Cam,
Why is Giu capped out on reps??? "Spread it around"? Does that mean I have to give SD a rep point?

[camaraderie]

HE is not capped...YOU are capped...you can't give more than one negative or positive rep to a person until you've given a lot more +/- rep to others. So YES...you have to give rep to SD first...but it does not have to be positive!

Sd look out man, we have to spread it around just like manure. You could be in trouble.

I just saw "The Boom Jack" video. Once again, congratulations! You really made it, Giu!

What is most impresive to me is that the first time I watch on of the videos I see a bit of information that I already know together with plenty of new concepts that overwhelm me a little. And I think "Oh my God! I'll have to see it 10 times, taking notes. I'll have to download the video so I can see it in the boat while practicing... and see if one day I can learn all those concepts and know thenm by heart". Then I see it again, using the pause and going back once in a while and I understand everything and I keep going "... ahaaaa, logical, ... ok, that makes sense,..., yeah, ... ahaaa". And then if I see it a third time it all looks like obvious information that I always knew. And I must say: teaching things in such a way is really an acomplishment.

The graphics are phenomenal, the sequence of concepts is perfect to be understood. If you were a teacher your students would be happy.

In this video there is a part that I don't understand, though. You say that in order tha change the twist "you can use the traveller, if you have one, you can use the main sheet, or a combinaition of both". Well, moving the traveller doesn't add nor release any vertical tension to the boom, does it? Therefore, it would equally change the angle of incidence all along the mainsail, without affecting the twis. Wouldn't it?

Then, going further, if I don't understand that I can't undertand what you say "changing mainsail twist by changing the traveller depends on wind velocity, heel and boat balance".

Could you please explain a bit these two concepts? Thanks

Moving the traveller will impart some tension if the deck (and the traveller track) is cambered (curved to match the curve of the deck) and if the change in traveller position changes the angle at which the wind encounters the sail, thereby changing the forces on the sail.

"Spilling the traveller" (which may just be my term) is something I do in variable winds when racing, because the best sail angle is constantly changing in respect to the course, but the wind itself may be steady. In other words, my helming is all about sailing to the mark, but my mainsail manipulation is about playing the winds that will take me there.

Would recommend both a vang, to improve sail shape and a boom brake, to help reduce the risk of getting whacked in an unplanned gybe. Boom brake hardware has come down quite a bit in price and is pretty easy to install.

The Scott BoomLock, the Dutchman BoomBrake, and the Wichard BoomBrake are all pretty good and can help prevent bad things from happening. The Wichard is the smallest, lightest, but least versatile of the three. The Scott is a bit more versatile but the most expensive of the lot. I have the Dutchman, which is a the largest, but most versatile IMHO, and reasonably priced.

Dog,

Looks like Cam's out to get you. Watch your rep points Cam has the magic button.
