modern bowls are made from plastic in black or brown - in earlier years they have been made from stone, wood - including lignum vitae, a very hard wood from the West Indies, and even rubber.
bowls are made in various weights and sizes. Diameter is 117/133mm - maximum weight is 1.59Kgs.
the running surface or crown of the bowl is slightly higher one side to create the "bias", causing the bowl to curve or "draw"
the jack is the round white or yellow plastic ball at which players aim their bowl
the jack is 63/64mm in diameter and weights 227/283 grams
the bowlers must get as many bowls as possible closer to the jack than the nearest of the opponent's bowls
the club green is divided into rinks on which seperate games are played
maximum green size is 40m - minimum 37m
maximum rink width is 5.8m -minimum 5.5m
the faster the green, the longer the bowls take to reach the other end
the speed is determined by the length and density of grass and the preparation in terms of rolling and grooming the grass
A slow green (heavy) means there is less arc with the biased bowl which doesn't travel as far and therefore takes less time to reach the jack
slow green is 11-13 seconds
fast green is 16-18 seconds
