Default How Does A Jib Work?

Thank you.

How does it relieve the pressure on the tiller? I do notice a strong force
on the tiller when there is some wind. I don't remember this on the Topper
that I used to sail earlier.


Very simply, the jib is set forward of the centre of lateral resistance
(the point about which all the lateral resistance of the hull and
underwater appendages combine to act) and the main is set aft of that
centre. If there's a large force on the tiller caused by the boat
wanting to turn up into the wind, then ease the main a little and trim
the jib a little tighter. If the force is caused by the boat wanting to
turn away from the wind, reverse it: main in, jib eased.

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.
