The green, ditch, banks and rinks
The World Bowls Laws of the Sport state that:
46.2 The length of the green in the direction of play must be between 31 metres and
40 metres
47.1 The green must be surrounded by a ditch.
48.1 The ditch must have a bank against its outer edge.
Ours meets all requirements, and should a bowl go into the ditch or hit the bank it won’t damage the bowl.
Here are a few illustrations (from the latest World Bowls Laws of the Sport) to show how the green divided, and also the minimum distances when playing:
