GETTING THE GREEN (MAT
UP)

When
the mast has been placed well up the green it is very easy to find your new
aiming line.

(1)
You
know your bank point which will give you the correct green on that side

*(2) *Go to a normal mat position
one to two metres from the tee (*in most games of bowls most
ends are played with the mat one to two metres from the tee. Unless the mat
goes up more than four metres the difference in aiming point is not worth
considering)*

(3)
Sight
the line to your bank point

(4)
Observe
how far away from the middle of the back of the new mat position this line
passes

(5)
This
is **exactly** how far your bank point
moves in for the new mat position

.

GETTING THE GREEN (JACK
OFF CENTRE)

This
is not as precise as the change for mat up

(1)
You
know your bank point which will give you the correct green on that side

(2)
Sight
a line through the new jack position to the bank and get the point this line
hits the bank

(3)
Picture
the distance x this point is from the rink number post

(4)
Add
or subtract this distance x from your bank point to get your new bank point

Geometrical
explanation (for those who liked geometry at school). The angles a must be
equal, hence the angles b must be equal, hence the lengths x must be almost
equal and Y is almost equal to x
