"an *angle* inward of the tangent"? Wow, do you know what a "tangent"
to a curve means?

Yes.

Let's hear it, what does it mean?

No need.

Guess your little knowledge just cannot answer it.

Do you? It certainly doesn't seem you do.

No tangent cuts inside/into the curve/circle.

And I never said it did. means
exactly what it says.

That's your pathetic little knowledge. "an *angle* inward of the
tangent" does not make mathematical sense.

Tangent is defined as a straight line intercepts a curve/circle at
only one point, so a tangent is always outside of the curve/circle.

If it didn't, there would be no centripetal force and the boat
would [missing not] turn.

Not really, forces are vectors, what angle do you think that the keel
and the centripetal force form?

And now we enter your obfuscation phase; where you attempt to make
your ignorance disappear by discussing irrelevancies.

Or your pathetic preposterousness.

Nope. Your irrelevancies.

"your pathetic preposterousness."

The keel is essentially a symmetrical underwater *wing*. For a
symmetrical wing to generate a force to the side (as the centripetal
force on the sailboat must be) it must operate at an *angle* to the
flow of fluid around it. If the boat is turning to the right, then the
keel must have a small angle to the right of the boats instantaneous
direction of travel and it is the direction of travel which is tangent
to the curve the boat is making.

According to Newton's Mechanism, the centripetal force is always
perpendicular to the path that the object is traveling on. Remember
the analogy that "the skis are the keel"? As in skiing, if you are
carving, the skis stead right on the track, point neither out nor in.
So is the keel traveling through water.

What prevents a sailboat from not *pointing* where it is *moving*?

Inertia.

Thank you for exposing your ignorance so plainly.

Your little knowledge doesn't shed the light.

Just to help you out a little, I've been sailing since I was 7 years
old and have competed at the world championship level.

Wow, sounds like our mighty Hungarian warrior has a serious
competitor. What did you win?

I didn't win. But I was good enough to be there. :-)

I was surprised that you didn't joint their conversation on sailing
earlier on between Walt and the mighty Hungarian Warrior.

No need.

Why not? Given that you argue with any body shows signs of "better
than you."

But go right on displaying your ignorance if you prefer.

And we have heard the story of the 9 yo boy in a skateboard park
bragging about doing "9."

More irrelevancies...

Not if you were bragging the 7 yo's achievements, it does.

Not English. Try again.
