THEORY OF ALIGNMENT
by Macka Jensen
Theory does not mean teaching bowlers to know what they
do not know; it means teaching them to behave as they do not behave
1. THEORY
This is the department of science which deals with the principles or methods of the delivery technique as distinguished from the practice or system of rules and the principles in performing the delivery action. These subjects are as follows;

2. THE AIMING LINE
a. Definition: This is the sighting angle used to offset the bias of the bowl from 0 to approximately 30 degrees right or left of the jack or target (See Diagram 1.)
b. When delivering a bowl:
(1) Draw shot; when playing the draw shot the width of the aiming line whether it is right or left of the jack or target can be anything from approximately 10 to 30 degrees. The width depends on the make, shape, weighting of the bowl and speed of the rink. These combining factors are explained briefly as follows; the older type make of bowls have a wider bias and the newer type bowls have a narrower bias. If the rink speed is slow the angle is narrow, if it is fast it is wide,
(2) Advanced shots; when playing advanced shots e.g. on-shots, running or drive shot, the offset angle can be anything from 0 to approximately 25 degrees right or left of the jack or target. Additional; see Angles of the Green. National Bowls Coaching Manual 1999
(3) When delivering a jack: It is the direct line of sight to the where the jack is required to be delivered.
