Fella, if you want to learn about the physics of sailing, maybe a better bet
than usenet, is your local library, or even Google.

That way, you can save people bashing their heads against a brick wall
trying to understand what your level of knowledge is.

I recommend "Sailing theory & practice - Marchaj" if you know anything about
physics, and something with "for dummies" in the title if you dont.

Thank you, but it raises more questions.

Won't the jib interfere with the main sail as it sits right in front of
the
mail sail albeit of smaller size?

When running, doesn't the mail sail block the jib, almost completely?

What is heeling?

When you say "above the center of buoyancy" do you mean in front of the
center of buoyancy or are you talking height?

Thanks

The main reason for a jib to exist is that its profile combines with
that
of
the mainsail when going upwind in a way that increase considerably the
overall lift. The reason is very aerodynamical and not very easy to
visualise, it has to do with the combination of the fluid flow
circuitations.

On the other courses it's more square metres of sail there to push more
without adding extra heeling on the boat, since they are at low height
above
the center of buoyancy.

At the beginning of your career you'll find very easy to steer the boat
upwind just on how the little red and green lines fly near the luff.

I am a newbie on a Laser Pico. Can someone explain to me what the jib
sail
does and how it works?
