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

It balances the rig to relieve pressure on the tiller, adds sail area, and
provides an aerodynamic "slot" in front of the main to accelerate the
airflow and increase efficiency of the main.

Adjust the jib similar to the main -- the luff should be pointing into the
relative wind except when running before the wind.
