To curl a curling stone, turn it to either the 10:00 position for a clockwise turn (curling to the right) or the 2:00 position for a counter-clockwise turn (curling to the left) upon release.
The curl of a curling stone is determined by the rotation imparted to it during delivery. This rotation, combined with the interaction of the stone's running surface (the "running band") with the ice, causes the stone to curve in its path.
Here's a breakdown:
-
Clockwise Turn (Curl to the Right): When releasing the stone, rotate the handle so it points towards approximately 10:00 (as viewed from above). This imparts a clockwise spin. As the stone travels, this spin causes it to curl towards the right for a right-handed curler.
-
Counter-Clockwise Turn (Curl to the Left): When releasing the stone, rotate the handle so it points towards approximately 2:00 (as viewed from above). This imparts a counter-clockwise spin. This causes it to curl towards the left for a right-handed curler.
The amount of curl can be affected by:
- Ice conditions: The texture and cleanliness of the ice significantly influence the amount of curl.
- Delivery speed: A slower stone will typically curl more than a faster stone.
- Amount of rotation: More rotation translates to more curl.
- Stone Condition: Nicks and imperfections on the running band of the stone can impact its trajectory and curl.
In summary, the curl is achieved by imparting a controlled rotation to the stone during release, using the 10:00 or 2:00 position as a general guide for clockwise and counter-clockwise rotations, respectively.
