Measuring the "size" of a lawn bowl can refer to two main things: its physical dimensions (like diameter and weight, which are set by regulations) or its position relative to the jack during a game to determine scoring. Based on the provided reference, the primary measurement discussed involves using a Tape Measure to determine the distance from the jack to a bowl during play.
Measuring Distance During Play
In the game of lawn bowls, the crucial measurement is the distance from the jack (the target ball) to each bowl. This determines which player's or team's bowls are closest and therefore score points.
- Tool Used: A Tape Measure is a fundamental tool for this purpose. Other specialized measuring instruments like calipers or string measures may also be used depending on the situation and local rules, but a tape measure is standard.
- The Process: To measure which bowl is closer to the jack, a tape measure is extended from the nearest point of the jack to the nearest point of the bowl. The shorter distance indicates the closer bowl. This is done for all bowls that are potential scorers (typically those within the confines of the rink and not "dead").
Special Cases: Bowls in the Ditch
Measuring becomes slightly more specific when a bowl ends up in the ditch surrounding the green. The provided reference clarifies this:
"When a bowl in the ditch is being measured against a bowl on the surface of the green and the jack is on the green, the measure should be conducted as normal for the bowl on the green. For the bowl in the ditch the measure shall be from the jack to the bowl."
This means:
- For a bowl still on the main green surface, the measurement is done from the jack to the bowl as usual.
- For a bowl that has gone into the ditch but is still 'alive' (e.g., it wasn't a delivery that went straight into the ditch, or it hit the jack before entering), its distance is measured directly from the jack to the bowl in the ditch.
Essentially, the tape measure is used to compare distances directly from the jack to the nearest edge of each bowl being considered, irrespective of whether they are on the green or in the ditch (provided they are live).
Measuring Physical Dimensions
While the provided reference focuses on measuring distance during a game, "measuring the size of a lawn bowl" can also refer to its physical specifications. Bowls used in competitive play must conform to strict regulations regarding their:
- Diameter: The bowl must fit through a standard ring gauge. Specific minimum and maximum diameters apply based on the bowl's weight.
- Weight: Bowls have regulated weights, typically ranging from about 2 lbs 8 oz to 3 lbs 8 oz (approx 1.13 kg to 1.59 kg).
- Bias: The bowl's bias (how it curves) is also tested using specialized equipment.
These physical measurements are typically done by manufacturers or regulatory bodies using specialized tools (like scales, gauges, and bias testing ramps) and are not something players typically measure during a game.
Why is Measurement Important?
Accurate measurement is fundamental to lawn bowls:
- Scoring: Determines which team/player scores points in an end.
- Fair Play: Ensures consistency and settles disputes over which bowl is closer.
- Regulation: Ensures equipment meets standards for competitive play.
In summary, while physical size (diameter, weight) is measured for regulatory compliance, the most common measurement involving a lawn bowl using a Tape Measure during a game is the distance from the jack, crucial for determining the score.
