Sheeted In: The end of the
Mainboom should be over the
inner edge of the cockpit
Sheeted In: The end of
the Jib Boom should be
just inside the inner edge
of the Gunwhale
Sheeted Out: The Mainboom
should sheet out to around 80º
to the Hull’s centreline
Sheeted Out: The Jib Boom
should sheet out to around 85º
to the Hull’s centreline
Good illustration of the Boom angles and
sail twist when sailing downwind (running)
Perfect angle to view the twist in both the
Jib and Mainsail leeches (back edges).
The Boom sheeting angles are perfectly
set up here and the sail leeches are
twisting open nicely to allow a smooth
airflow over both sails, without loosing
power through excessive twist.
Nice shape in foot of both sails. Adjust
position of the Clew Hook and silicone
rings to achieve this set up on your boat.
Note that the Jib foot has been set slightly
flatter than the Mainsail foot.
